How engagements work

One senior engineer, end to end

You work with the person scoping, building, and explaining the system — no agency handoff or junior layer.

12 years shipping web & mobile products

The program

From your idea to a working product, with me beside you the whole way.

You build it with your own hands, and I sit next to you the whole time: helping you scope, unblocking you when you're stuck, and stepping in where real engineering judgment is needed. By the end, the focused first version is live and completely yours.

S1Session 1 · 90 min

Validate & first build

We pressure-test your idea, keep only the features that matter, set up your AI tools, and you ship your first working screen before the session ends.

S2Session 2 · 90 min

Core feature, real data

You build the one feature your idea lives or dies on, connected to real data instead of a mockup.

S3Session 3 · 90 min

Polish & launch

We polish the rough edges, make it fast, and put it live. You leave with a link you can proudly send to anyone.

Expectations

What's realistic in 3 sessions

Realistic

  • A working web product with one core feature, connected to real data
  • Sign-up, forms, email notifications, payments through a hosted checkout
  • A version 1.0 deployed on your own domain, ready for first users
  • AI tooling set up on your accounts so you can keep building after we finish

Not in 3 sessions

  • A native mobile app published in the app stores
  • Deep integrations with legacy or enterprise systems
  • A large product with many roles and features: that's a custom MVP engagement
  • Formal security audits and production-scale load testing

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

typically 2–4 weeks

Discuss the opportunity

02 · Process Automation

Turn manual workflows into pipelines

Agents and integrations that handle repeatable steps across tools, with human review where it matters.

Good for

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

typically 1–3 weeks

Map this workflow

03 · Performance & Optimisation

Make your product feel instant

Profiling, Core Web Vitals, query and infra cost cuts. Everything measured before and after, no guesswork.

Good for

  • Apps that got slow as they grew
  • Cloud bills growing faster than revenue

typically 1–2 weeks

Discuss the bottleneck
Rocket launching from building blocks

04 · Done-for-you MVP

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

typically 3–6 weeks

Discuss your MVP

  • A clear MVP plan: what it does, who it's for, which features make the cut
  • User flow and wireframes

The Blueprint fee is fully deducted from the project price if I build the product after the plan. It doesn't apply to Build With Me: those are separate paths.

Why direct delivery

Why work with me

I'm a Senior Full-Stack Engineer with 12 years of 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.

Whether you want an AI feature, an automated workflow, or to learn to build things 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 is never a constraint.
