Software Engineer | Python & TypeScript | Web, Data & System-Oriented Applications
🇧🇪 Belgium • FR / EN / NL • Open to backend, full-stack, frontend, and data-oriented roles

I build structured web and data-driven systems with a focus on reliability, clarity, and maintainability.
Comfortable moving between backend logic, API design, data workflows, and user-facing interfaces—especially when the product needs predictable behavior under real constraints (performance, state consistency, offline usage, integration limits).

• Backend & APIs: Python services, REST APIs, authentication flows, business rules, predictable state handling
• Web applications: React / Next.js interfaces, clean UI integration, performance-minded implementation
• Data workflows: SQL + Pandas pipelines, reproducible processing, monitoring/inspection views
• System thinking: workflow-driven design, consistency guarantees, auditability, long-term maintainability

Languages: Python • TypeScript
Backend: Django • FastAPI • Flask • REST APIs • JWT Auth
Frontend: React • Next.js (PWA-ready)
Data: SQL (PostgreSQL, MySQL) • Pandas • Streamlit
AI integration: OpenAI API • Hugging Face
Infra & tooling: Docker • Git/GitHub • CI/CD • (basic)
Design: Figma

• IBM AI Developer Certificate (Coursera) — Generative AI & integration (OpenAI/Hugging Face)
• Full-Stack Web Development Bootcamp (MolenGeek, Brussels) — 34 weeks (2023–2024)
• Business Informatics (2 years completed) — ISFCE Brussels

Opportunities where structured thinking, clean implementation, and long-term maintainability are valued—across: backend, full-stack, frontend, or data-oriented work.
