I ship working systems inside other people's constraints — usually faster than the meeting that scoped them.
- Shipped an AI code-review pipeline into daily use by 19 developers on self-hosted GitLab
- Built and run MCP servers in production against real internal systems
- Owned delivery of 17 concurrent projects across EU/national tenders
Tech Lead at an environmental-technology company. Founder of two products. Integrated MSc in Computer Science and Engineering. MBA (in progress).
Case studies
- AI-assisted code review on self-hosted GitLab
- The constraint

- Time to first value
- First useful review comments within the first sprint
- MCP servers over real internal systems
- The constraint
- Live internal systems, an evolving protocol, no established playbook
- Outcome
- Agents working against real internal state, daily
- Time to first value
- First useful output within the first sprint
- careerexplorer.ai: a solo-built AI career coach
- The constraint
- One person end to end — product, code, infrastructure, content
- Outcome
- 2,350 users, 12,000+ coaching conversations
- Time to first value
- First useful output within the first sprint
- A volunteer management system on a zero budget
- The constraint
- Zero budget, non-technical operators, built in spare time
- Outcome
