Start with the operational problem

AI should improve a real workflow—not become another disconnected tool.

Look for repeated work, delayed responses, missing context and fragile handoffs before choosing a model or platform.

Customer enquiries arrive through several channels and some are missed.

Employees repeatedly copy information between email, spreadsheets and a CRM.

Customers wait too long for an initial response.

Proposals, summaries or routine documents are recreated from scratch.

Company knowledge is scattered across files, inboxes and individual employees.

AI tools produce inconsistent results and remain disconnected from daily work.

An automation fails when an API, prompt or business rule changes.

Systems we can design and build

One complete process, not a collection of AI features

Each system starts with an operational outcome and makes the human-control boundary explicit.

Customer communication

Turn incoming email, website forms or messages into a structured, reviewable workflow.

  • Classify and route enquiries.
  • Extract dates, locations, requirements and missing details.
  • Prepare a response in the customer’s language.
  • Create a consistent follow-up task.

Human control: Sensitive, unusual or high-impact cases are escalated to a person.

Sales and lead management

Connect the first customer message to the next useful commercial action.

  • Create or update CRM records.
  • Qualify leads using agreed business rules.
  • Prepare proposal drafts.
  • Schedule reminders and summarise history before a conversation.

Human control: Pricing, commitments and important commercial decisions remain under human control.

Internal AI assistants

Help employees find and use trusted company knowledge.

  • Search policies, procedures and product information.
  • Answer internal questions with source references.
  • Prepare onboarding guidance.
  • Identify when the available information is incomplete.

Human control: The assistant shows sources, respects access rules and says when it does not know.

Documents and operations

Reduce repetitive document handling without hiding the underlying process.

  • Extract structured data from incoming documents.
  • Validate required fields.
  • Prepare routine reports, summaries or forms.
  • Route exceptions for manual review.

Human control: Important steps remain auditable and exceptions follow a documented review path.

Reporting and management

Turn operational data into a clearer management view.

  • Produce recurring operational summaries.
  • Identify delayed or incomplete work.
  • Group recurring customer issues.
  • Prepare a brief with links to the underlying data.

Human control: Managers verify context and make decisions; the system organises evidence.

How I can help

Solve the bottleneck. Build the system. Keep control.

Lost enquiries, slow replies, manual coordination, scattered data and content that never gets published are business problems first. I find the bottleneck and build the smallest reliable system that changes the result.

The goal: recover time and opportunities, improve the customer experience and give the owner a clearer operating view.

Built on fundamentals, not fashion

  • Process and service design
  • Systems and data architecture
  • Software engineering and security
  • Measurement and operational reliability
  • AI governance and human decision rights

Travel operations and client experience

Madeira Private Rides

Business example

When this is the problem

Enquiries, route details, customer messages, photos and follow-ups live in separate places. Each trip guide takes manual effort, the client experience varies and valuable first-party content is difficult to reuse.

What changes

One connected client journey—from the first enquiry and route design to a polished trip guide, faster follow-up and reusable destination content that supports organic discovery.

What I can build

  • Structure pickup, route, timing, inclusions, price and driver information.
  • Prepare consistent mobile-friendly, print-ready guides and multilingual messages.
  • Turn approved, geotagged trip photos into ordered route stories and reusable content.
  • Connect service operations with useful website and search content.
Built on
Customer journey mapping, service design, content modelling and multilingual UX.
Human control
The owner confirms availability, price, route safety, client promises and publication.

Live operations and data

Portugal Flight Data Monitor

Engineering example

When this is the problem

Flight data grows while operators still need fast screens, current alerts and predictable provider costs. Deep lists, duplicate synchronisation and dashboard-wide scans turn a useful monitor into an operational risk.

What changes

A responsive operational view with reliable background synchronisation, clear failure states and capacity controls—so the team can act on current information without waiting for the system.

What I can build

  • Serve the monitor from PostgreSQL through a Fastify API, with REST for reads and SSE for controlled updates.
  • Use cursor pagination, compact payloads and precomputed daily aggregates instead of loading complete datasets.
  • Run synchronisation as bounded, idempotent jobs with locks, retries, progress and provider-budget controls.
  • Measure latency, database pressure, queue health and failure rates with reproducible load tests.

Example design target: 250,000 active flight records, 5 million historical events and 20 concurrent operators; stress profile up to 1 million flights and 100 users.

Built on
Data modelling, concurrency control, performance engineering, fault tolerance and observability.
Human control
Paid provider calls, retries and manual synchronisation stay inside explicit cost and authority limits.
Discuss a monitoring or data system

Content operations and promotion

Social media management and growth

Service capability

When this is the problem

Strong expertise stays in drafts, publishing is sporadic and the same post is copied between platforms. Without a calendar, approval path or learning loop, promotion consumes time without building momentum.

What changes

A consistent content engine that turns verified expertise into discoverable, platform-native publishing and more qualified conversations with the right audience.

What I can build

  • Research and verify topics before they enter the content calendar.
  • Adapt one strong source into distinct posts for LinkedIn, X and other relevant channels.
  • Coordinate drafts, assets, approvals, publishing slots and final status in one workflow.
  • Review qualified engagement and improve themes, formats and distribution without chasing vanity metrics.
Built on
Positioning, editorial strategy, audience research, experimentation and measurement.
Human control
Final claims, sensitive replies, account access and publication policy remain under owner approval.
Discuss social media operations

Product and software delivery

Custom web and mobile applications

Service capability

When this is the problem

Spreadsheets, chats and fragile no-code connections can no longer hold the workflow safely. Information is duplicated, permissions are unclear and the team works around the tools instead of through them.

What changes

A purpose-built web or mobile application with a clearer interface, dependable data and less manual coordination—using AI only where it creates a real advantage.

What I can build

  • Turn the problem into user journeys, requirements and a testable product scope.
  • Design the interface, data model, APIs, integrations and access rules as one system.
  • Build prototypes and production applications with tests, deployment and monitoring.
  • Document ownership, recovery and the next improvements after launch.
Built on
Product discovery, interaction design, full-stack architecture, security and quality engineering.
Human control
Business rules, permissions and release decisions are agreed before the application receives real authority.
Discuss a custom application

Decisions before development

AI, automation and architecture consulting

Advisory capability

When this is the problem

The team has several AI ideas but no agreed priority, business case or safe authority boundary. Vendor proposals add tools before anyone has defined the process, evidence or success measure.

What changes

A defensible written decision: what to change, what to build or buy, where AI belongs, what must stay human and which small experiment should happen next.

What I can build

  • Map the current process, bottlenecks, exceptions, decision rights and available evidence.
  • Choose between rules, conventional automation, an AI assistant, a bounded agent or no automation.
  • Compare build, buy and integration options across cost, risk, privacy and maintainability.
  • Produce a written architecture, priority roadmap, acceptance criteria and next experiment.
Built on
Systems thinking, operations management, decision science, AI governance and economics.
Human control
Assumptions and trade-offs are made explicit; the final business decision remains yours.

Workflow example

From customer enquiry to controlled follow-up

This example architecture changes with the company’s rules, systems, data and risk level.

  1. 01

    Customer inquiry received

  2. 02

    Requirements extracted

  3. 03

    Missing details identified

  4. 04

    CRM record created or updated

  5. 05

    Response draft prepared

  6. 06

    Employee reviews and sends

  7. 07

    Follow-up scheduled

  8. 08

    Workflow logged and measured

Prices, promises and exceptions are reviewed by an employee before a response is sent. The workflow remains logged so response time, exceptions and outcomes can be measured.

Who this is for

Small service businesses where speed and context matter

The best first project is usually a frequent, rules-based workflow with a clear owner and a measurable starting point.

Tourism and transport operators

Hospitality and property services

Local service companies

Agencies

Small B2B teams

Businesses serving customers in more than one language

How we work

Reduce uncertainty before expanding the system

Each stage has a concrete output, a review point and a clear owner.

  1. 1

    Workflow review

    Map how the process works today, where time is lost, which exceptions occur and what should not be automated.

    Output: Current-state workflow, opportunity map and initial success measures.

  2. 2

    Solution design

    Define the system boundary, integrations, business rules, human approvals, fallback behaviour and expected operating cost.

    Output: Proposed workflow and implementation scope.

  3. 3

    Working prototype

    Test the highest-risk assumptions with representative examples before building the complete system.

    Output: A working prototype and evidence about what needs to change.

  4. 4

    Development and integration

    Connect the agreed tools, implement the workflow, add validation and prepare the operational interface.

    Output: A tested system in the target environment.

  5. 5

    Launch and documentation

    Introduce the system to its users, document ownership and define what happens when something fails.

    Output: Production launch, operating guide and support plan.

  6. 6

    Monitoring and improvement

    Review quality, exceptions, operating cost and business results as the process changes.

    Output: Prioritised improvements based on real usage.

Ways to work with us

Choose the smallest engagement that reduces the next risk

Projects are scoped after a workflow review. We do not recommend automation before understanding the process and its exceptions.

AI Workflow Review

A focused review of one business process to determine whether automation is useful, feasible and measurable.

Best when the friction is known but the right system is not.

Rapid Prototype

A small working system that tests one valuable workflow on representative data.

A well-defined prototype can often be tested within one to two weeks after scope and access are agreed.

Custom AI System

Design, development and integration of a complete workflow with validation, human review, logging and documentation.

Best for a frequent process with a clear owner and a measurable outcome.

Continuous Support

Ongoing monitoring, maintenance and improvement after launch.

Covers quality evaluation, integration maintenance, cost monitoring and prioritised improvements.

Reliable by design

Automation where it helps. Human control where it matters.

AI output is not treated as automatically correct. Reliability, ownership and fallback behaviour are part of the design.

  • Critical actions require the right level of human approval.
  • Important steps are logged and traceable.
  • Errors and uncertain results have an explicit path.
  • Only necessary data is shared with each service.
  • AI and API costs are monitored.
  • Quality is evaluated on representative examples.
  • Essential workflows have a fallback when an AI provider is unavailable.
  • Ownership is documented after launch.

What we measure

Define the baseline before claiming improvement

Measures are chosen before implementation and tied to the workflow being changed.

No unsupported results or generic transformation claims.

Frequently asked questions

Practical questions before a workflow review

Is every repetitive process a good candidate for AI?

No. Some processes should use simple rules, conventional automation or no automation at all. We recommend AI only when it adds useful flexibility or understanding.

Can you work with our existing software?

Often, yes. We start by reviewing the systems already in use and the integration options they provide. Replacing the entire stack is rarely the first recommendation.

Will the system make decisions without our team?

That depends on the risk of the action. Critical prices, commitments, payments, legal decisions and sensitive customer situations should have appropriate human approval.

How quickly can we test an idea?

A focused prototype can often be tested within one to two weeks after the workflow, data access and success criteria are agreed. Larger integrations require a separate scope.

What happens after launch?

We can provide ongoing monitoring and support. AI models, APIs, prompts, integrations and business rules change, so a production system needs a clear owner and maintenance plan.

How much does an AI system cost?

Cost depends on the workflow, integrations, data quality, risk level and required support. We begin with a workflow review so the estimate is based on the real process rather than a generic package.

Do we need to prepare our data first?

Not always. The review identifies which information is available, what is missing and whether the current data is sufficient for a safe prototype.

Do you provide an AI tool or a complete workflow?

The focus is the complete working process: inputs, rules, integrations, AI assistance, human approvals, logs, fallback and ongoing ownership.
