I build full-stack web applications and MVPs end-to-end. React/Next.js frontends, Express, Python (Django/FastAPI) or ASP.NET Core backends, deployed and production-ready. My work includes Dealsbuzz.lk, a live e-commerce store I built and run (Next.js, Express, PostgreSQL) with product catalog, pre-orders, order tracking, and payment flow, serving real customers in production, not a demo. What I deliver: MVP development for startups, from idea to a deployed, working product E-commerce platforms and multi-vendor marketplaces (see ezBuy in my portfolio) Full-stack web apps, dashboards, and admin panels REST APIs, backend systems, and third-party integrations Bug fixes, performance improvements, and refactoring of existing codebases Stack: React, Next.js, TypeScript, Tailwind • Node.js/Express, Python (Django/FastAPI), ASP.NET Core, C# • PostgreSQL, MySQL, MongoDB • Docker, Git. You get clean architecture, version control, realistic timelines, and code your next developer won't have to rewrite. Send me what you're trying to build, even a rough idea, and I'll give you an honest read on scope and timeline.

I'm a web developer and data scientist with a BSc in Information Technology (SLIIT) and a BSc in Physical Science (Statistics). I build reliable, well-structured web applications and enjoy solving complex technical problems. Technical skills: ✅ Backend: C#, ASP.NET Core MVC, Node.js, Java, PHP ✅ Frontend: React.js, Next.js, Angular, jQuery ✅ Databases: SQL Server, MySQL ✅ Mobile: Android ✅ Data & Analytics: Python, R (data handling, analysis) ✅ API design & integration, MVC architecture I have hands-on experience across the full development lifecycle — from database design to backend logic to frontend implementation — and I'm comfortable working across both the .NET and JavaScript ecosystems depending on what a project needs. When I start a new project, I make it a priority to talk directly with the client first. Understanding your goals and vision clearly upfront helps me deliver work that actually fits what you need, not just what was written in a task list. Thank you for considering my profile — I look forward to working with you. Kavinda Piyumal
