AI INTEGRATIONPROCESS AUTOMATIONPERFORMANCEOPTIMISATIONLLM PIPELINESEVALSCORE WEB VITALSSHIP IN 3 SESSIONS

01 — The program

From idea to a working v1 — with me beside you the whole way.

You build. I sit next to you — scoping, unblocking, and stepping in where real engineering judgment is needed. You leave with a deployed product you own completely.

S1

Foundations & first build

Set up the AI tooling, scope v1 down to what matters, and ship your first working screen — in session one.

S2

Core feature, real data

Build the one feature your idea lives or dies on — connected to real data, not a mockup.

S3

Polish & ship

Fix the rough edges, run a performance pass, deploy — and leave with a link you can send to anyone.

02 — Services

Already have a product? I make it smarter, faster, and less manual.

Plug connecting to circuit nodes

01 · AI Integration

Add AI to the product you already have

LLM features that survive production: retrieval, structured output, evals — not a chat widget bolted on.

Good for

  • SaaS teams adding their first AI feature
  • Products with data an LLM could leverage
Gear inside cycle arrows

02 · Process Automation

Turn manual workflows into pipelines

Agents and integrations that take a 14-step routine down to one — with human review where it matters.

Good for

  • Teams drowning in copy-paste operations
  • Back-office work: invoices, reports, intake
Speedometer with lightning bolt

03 · Performance & Optimisation

Make your product feel instant

Profiling, Core Web Vitals, query and infra cost cuts — measured before and after, not vibes.

Good for

  • Apps that got slow as they grew
  • Cloud bills growing faster than revenue
Rocket launching from building blocks

04 · MVP Build

Or I build the first version for you

When you'd rather not build it yourself: a scoped v1, shipped fast with the same AI-assisted workflow.

Good for

  • Founders with budget but no time
  • Validating before hiring a team

03 — Why me

Why work with me

I'm a Senior Full-Stack Engineer with 10+ years building web and mobile products for teams across Europe and the US. AI tools like Claude Code and Codex are part of how I ship real features — in production, for paying users, not in demos.

Whatever your goal — an AI feature, an automated workflow, or learning to build yourself — you work directly with the person doing the engineering. No agency layer, no juniors.

Every engagement is shaped around your goal and your starting point — not a fixed curriculum. Building for the web, a mobile app, or a tablet experience? I work across React, React Native, and responsive web, so the platform your users are on isn't a constraint.
