Back to original languageAbout Kjell
Full-stack developer (React, TypeScript, Node.js) with 3 years of hands-on experience. I build web applications and websites end-to-end: architecture, database design, front-end, security, and deployment.
My core stack: React, TypeScript, Node.js, and PostgreSQL (Supabase), deployed on Cloudflare. For fast content sites, I work with Astro.
Recent projects:
• Werfronde: multi-tenant planning PWA for construction companies, with Row Level Security, mandatory 2FA, and Google Maps integration (Routes API, Places).
• Klantenportaal: SaaS portal where website clients manage their own content, with roles and publish/rollback flow.
• Real-time dashboards and data pipelines on Cloudflare Workers (KV and R2).
What you can expect from me: measurably fast solutions, security by design, and independent delivery from initial analysis to go-live. Available 4 to 5 days a week, on-site in the Ghent, Kortrijk, and Bruges region, or remote. Immediately deployable.
