I'm a software engineer and AI practitioner who thrives at the intersection of scalable product engineering and intelligent systems. Over 5+ years I've designed and delivered production-grade solutions across full-stack platforms, real-time data pipelines and AI-powered ecosystems — from global coworking platforms and telecom automation to enterprise sales tools and voice-enabled multi-agent AI.

I own delivery end-to-end — from React, Next.js & Angular frontends to Node.js (NestJS) & Java backends, with GraphQL, Apache Kafka and AWS underpinning the architecture. I design and integrate agentic AI using LLMs, RAG with Pinecone and tool-based retrieval workflows built on LangGraph, and I've led complex third-party integrations across payments, CRM and communications platforms to power real business workflows.

Beyond industry work I'm a published researcher with peer-reviewed contributions in deep learning and NLP — outbreak-related tweet detection for public-health surveillance, hate-speech detection in Sinhala (a low-resource language), and real-time traffic-flow estimation with YOLOv4 + SORT, presented at ISCRAM 2021 (Virginia Tech). Academically, I hold a First Class Honours BSc (Hons) in Management & IT — awarded the Gold Medal for best academic performance — and a Postgraduate Diploma in Data Science & AI.
