Over mij
Hi, I'm Chamath, a full-stack software engineer from Sri Lanka. I build production web apps with Next.js, TypeScript, Node.js and Supabase, and I work daily on a live SaaS platform handling 30,000+ messages a day.
I can help you with SaaS MVPs, client portals and dashboards, WhatsApp Business API integrations, AI chatbots trained on your own documents, and fixing apps built with Lovable, Bolt or Cursor.
You get clean code you own, clear daily updates and support after delivery. Message me with your idea and I'll reply with a plan.
