Skills

Four skills, with the evidence in the code

01

LLM integration

Putting a language model to work inside an application, without handing it what has to stay exact.

  • Claude API on the server, tools and web search
  • Structured answers validated by a schema (Zod)
  • Spending cap, call log, a mode without AI
02

Agent-driven development

Developing with Claude Code the way you lead a team: written instructions, checked work, human decisions.

  • Code review and security review sub-agents
  • Hooks, project memory and MCP servers
  • Specifications, tests and CI before every merge
03

Full stack .NET and TypeScript

Complete applications, from the database to the interface.

  • C# / .NET 10, ASP.NET Core, EF Core, PostgreSQL
  • TypeScript, Node.js (Fastify), React, Next.js, Blazor
  • xUnit, Vitest and Playwright tests; GitHub Actions
04

Application security and NIS2

Security built into the code, and a tool for SME NIS2 compliance.

  • JWT, two-factor authentication, secrets out of the code
  • Security headers and CSP, as on this site
  • ClawkWerk: CyFun 2025 self-assessment, public source code
Understand NIS2 and CyFun
Frequently asked questions

Questions I get asked

The questions I get asked most often.

Are you looking for a job?

Yes. I am looking for a full stack developer role focused on AI, in Wallonia, Brussels or remote. My CV can be downloaded from the CV page.

Does AI write your code?

Largely, yes, and I do not hide it: many commits are co-authored by Claude. I write the specifications, have sub-agents review the work, and nothing is merged without green tests and my own review.

Do you still do cybersecurity?

It is part of my work as a developer: authentication, secrets, security headers. I also wrote ClawkWerk, a CyFun / NIS2 self-assessment tool for SMEs (public source code, non-commercial use). I do not perform penetration tests.

Hiring?

Write to me to talk about it: a simple, direct first conversation.
