Senior full-stack engineer building software that ships and thinks.

With 5+ years of experience, I design and deliver production web applications end-to-end for clients across the US, Australia and Sri Lanka. I've led 12+ deliveries with React, Next.js, TypeScript and Node.js, backed by AWS serverless architecture, CI/CD automation and test-driven development.

Lately my focus is AI product development: LLM integration, RAG pipelines and prompt engineering across Claude, Gemini, OpenAI and Groq. I'm currently reading an MSc in Artificial Intelligence at SLIIT, and I shipped Sri Lanka's first AI-native expense tracker.

PaySutra

PaySutra

Sri Lanka's first AI-native expense tracker, built and shipped solo.

Users log expenses by texting casual Singlish or English messages, or by sending bank-SMS screenshots. LLM and vision pipelines (Groq, with model fallback and rate-limit handling) parse them into structured transactions with a preview-confirm step. Includes a Telegram bot client with daily reminders and budget alerts, dashboards, savings goals, net-worth trends, a bilingual English/Sinhala PWA, and row-level security on every table, all on a $0/month infrastructure footprint.
