About Me
I'm a software engineer who builds systems that scale and work in production. I work across the full stack—from backend services in TypeScript, NestJS, Python, and FastAPI to frontend applications in React and Next.js. Whether you're a startup or scaling to 150+ employees, I help build platforms that are reliable, automated, and easy to manage as your business grows.
I specialize in AI systems—building agents, implementing retrieval pipelines, and integrating LLMs into real products. I design secure AI tools for regulated environments where everything needs to be traceable, compliant, and production-grade. I work with vector databases, prompt engineering, and Azure infrastructure to build systems that are both intelligent and safe for enterprise use.
What I bring to teams is efficiency. I automate repetitive tasks, improve CI/CD workflows, introduce better debugging tools, and help engineers solve problems faster. I mentor developers, set up monitoring systems, and build features that reduce operational friction. Good engineering is about removing bottlenecks—both technical and human.
I deliver end-to-end solutions for FinTech and InsurTech companies—from authentication and payment systems to compliance automation and third-party integrations. I write maintainable code, build scalable infrastructure, and create systems that teams can understand and evolve. My goal is to help your business grow without getting stuck on technical debt or fragile architecture.

Professional Experience
AI Systems Engineer
Belfius
At Belfius, I'm building AI systems that work within the strict constraints of a regulated bank. This means taking experimental AI technology and making it production-ready, secure, and compliant. I work closely with InfoSec and Architecture teams to ensure everything we build meets banking standards.
- Built AI agents that help with internal operations—automating tasks that previously required manual work
- Designed retrieval systems that let LLMs access bank knowledge safely, using vector databases and hybrid search
- Set up Azure infrastructure with proper security controls—managed identities, encryption, zero-trust policies
- Created FastAPI services that connect AI models to enterprise data while maintaining strict access controls
- Worked with security teams to ensure AI systems are auditable, traceable, and compliant with regulations
- Took AI prototypes from concept to production with monitoring, versioning, and proper deployment pipelines
- Contributed to AI governance discussions—helping define how the bank evaluates and uses AI responsibly
