Build · Hands-on senior engineering
Shipping code from day one.
Your team knows what's slowing it down and has no time to fix it. I join hands-on, AI-first, and take those problems on. When I leave, your codebase and your team are faster than before.

Is this for you?
- 01
A critical part of your system keeps breaking, and your team has no time to fix it properly.
- 02
Your codebase has grown faster than its structure, and every new feature takes longer.
- 03
You need senior capacity now, not after a three-month hiring process.
- 04
You want your team to get more out of AI by seeing it work in your own codebase.
What I take on
- Fixing what's broken:
- data pipelines, integrations, performance and reliability.
- Architecture and refactoring:
- untangling the codebase so the team can move fast again.
- Features end to end:
- from idea to production, across frontend, backend and infrastructure.
- Setting the bar:
- code reviews, tests, observability and CI/CD, so quality is the default.
- Agentic engineering:
- your codebase and workflows set up so AI agents can build features and fix bugs in them.
Ways to work together
- 01
Embedded
a few days a week as part of your team, over several months.
- 02
Focused mission
one clearly scoped challenge, with my full focus for a set period.
Tech I work with
- Languages & frameworks
- JavaScript / TypeScript, Node.js, React, REST APIs
- Databases & storage
- MongoDB, Redis (incl. RedisTimeSeries), SQL, time-series databases (Prometheus, VictoriaMetrics)
- Infrastructure & DevOps
- AWS, Docker, Kubernetes, Linux, CI/CD
- Observability & tooling
- Grafana, Kibana, Git
- AI & agentic engineering
- coding agents (Claude Code and others), AI code review (CodeRabbit, Greptile), agent frameworks (LangChain, Mastra), AI observability (Langfuse), context engineering
I pick up new stacks quickly, and with AI faster than ever.
Why me
From developer to Head of Software, I stayed hands-on and kept shipping to production. As Head of Software Development at Amperecloud, I built products from scratch and drove AI adoption across the company. I still ship, as your fractional CTO or embedded in your team. I think in products: code matters when it solves a problem for the people who use it. I work in short iterations and tell everyone involved where things stand.
How we work together
We talk.
A free 30-minute call. You tell me where you are and where you want to go. I'll tell you whether I can help, and how.
We shape it.
Together we define the scope and the way of working: two days a week as your fractional CTO, a focused mission on one specific challenge, or a workshop series for your team.
We get to it.
I work with you and your team, hands-on from day one.
Where does your tech need to be a year from now?
Let's work it out in a free 30-minute call: what it would take, and whether I'm the right person for it.
