Services

Most of what I do falls into a few recognisable shapes. Here's what each one looks like in practice, so you can tell quickly whether it's the conversation you wanted to have.

What I build with

The tools I reach for, by discipline.

Full-stack JavaScript development

One language from the browser to the server, so the contract between them is written once instead of maintained twice. What I leave behind is the component and API foundation a team keeps shipping on — not just the screens they asked for this quarter.

Frontend
  • React.js
  • Next.js
  • Vue.js
  • Tailwind CSS
  • Material UI

Styling libraries picked for the use case rather than by habit.

Backend
  • Node.js
  • Express.js
  • Nest.js

Agentic Python development

A service that hosts agents, not a notebook that calls a model. A router and domain specialists behind a real API, retrieval that grounds answers in your own data, and a trace on every exchange — so when a run does something surprising you can see why rather than guess.

API
  • FastAPI
  • Flask
Orchestration
  • LangChain
  • LangGraph
Retrieval
  • Advanced RAG
  • ChromaDB
Tracing & evals
  • LangSmith

Database management

Schema design that survives the features nobody has written yet. Relational where the shape is known, document where it genuinely isn't, and field-level encryption where the data is sensitive enough to earn it.

  • PostgreSQL
  • MongoDB

Engagement shapes

The same stack, in the arrangements it usually gets used in.

Architect and build a platform

Taking something from an idea and a deadline to a running system — the serverless backend, the frontends against it, and the release cadence that keeps it moving.

  • Serverless AWS backend — GraphQL edge, single-resolver compute, Postgres with per-request encryption where the data warrants it
  • React and React Native surfaces built against the same contract
  • Auth, roles and audit trails designed in rather than bolted on
  • CI/CD and the component foundations the team keeps shipping on
2–3 months to a production release, enterprise scopeDetail

Put AI features into production

The gap between a working prompt and a feature you can put in front of regulated users — routing, guardrails, audit trails, and a cost you can predict.

  • Amazon Bedrock and SageMaker in multi-agent workflows
  • Router plus domain specialists rather than one prompt doing everything
  • Guardrails and full audit trails on every exchange
  • Durable sessions humans can join and review
Weeks, usually alongside an existing platformDetail

Own a product surface end to end

Longer-running work where I hold the architecture, the release cadence and the roadmap conversation — not a set of tickets, a system.

  • Architecture and technical roadmap held over quarters, not sprints
  • Multiple product surfaces on one shared codebase
  • Direct work with your team under my own name
  • Mentoring — code review, architecture guidance, onboarding onto shared foundations
Ongoing — the longest of these has run 2+ yearsDetail

Review an architecture

A second pair of eyes on a system before it's expensive to change: where the trust boundaries actually sit, which paths to data bypass the ones you meant, what scales and what only looks like it does.

  • System, component and data-flow walkthrough
  • Trust boundaries and authorisation paths mapped against the real code
  • Bottlenecks identified with the reasoning, not just a verdict
  • Written findings you can hand to the team

What an engagement looks like

  1. 01

    A call, then a written shape

    Half an hour on what you're building and what's in the way. You get back a written scope — what I'd build, in what order, and what I'd deliberately leave out.

  2. 02

    Ship the smallest true thing

    A live slice teaches more than another month of planning. The first release is small, real and in production, and the plan adjusts around what it tells us.

  3. 03

    Cadence you can see

    Regular releases against the roadmap, and the roadmap revisited as we go rather than once at the start. Nothing about progress should be a surprise.

  4. 04

    Handover that holds

    The team ends up on foundations they can keep building on — documented, reviewed, and with the reasoning behind each decision written down.
