I build AI solutions professionally at WEBINFORM — production LLM features, APIs, and automation for web applications and ERP-integrated systems — and, on my own time, local-first context infrastructure, agent orchestration tooling, and the integrated AgentSec security suite. I'm a BSc AI student at VU Amsterdam and I'm looking for full-time AI engineering, AI solutions, integration, automation, or agent-infrastructure roles.
- > Build internal AI tools and production LLM functionality for web applications and ERP-integrated systems: APIs, automation, backend logic, and user-facing AI interfaces.
- > Took over an inherited AI-first service with architecture, security, compliance, and prompt-injection problems — reverse-engineered its undocumented integrations, repaired it, and cut LLM API costs by roughly 40%.
- > Delivered 20+ websites/webshops, three internal systems, and a user-facing platform; two ERP/AI integration projects with direct involvement in discovery, solution design, client coordination, and pricing.
- > Coursework includes machine learning, computational linguistics, multi-agent systems, and the mathematics underneath them.
- > Taught programming fundamentals and game development to students aged 10–16.
- > Developed custom curricula and lessons for introductory Python and Scratch courses.
- > Supported project managers: ticket preparation and processing, incoming client communication, work coordination, and incident escalation.
- > Performed cross-system checks and Playwright-based pre-tests before releases.

Engineering notes from building the projects above — each links to the repository where the pattern is implemented
Fail-closed decision hooks for Claude Code and Codex: safe-command fast paths, chained-command bypass protection, and observe/prompt/enforce modes. Implemented and tested in the repo.
Allowed-roots path validation, destructive-command deny patterns, and regex credential redaction of subprocess output — the policy and redaction modules carry the unit tests.
I'm open to full-time engineering and AI roles. Based in Rotterdam, NL — remote / hybrid. No sponsorship required. Email is fastest.
