01Profile
I turn real constraints into systems that keep working.
Physical Science undergraduate in the Faculty of Applied Sciences at Rajarata University of Sri Lanka and engineer at Nora Software. I design multi-agent systems on Google ADK and Gemini, computer-vision pipelines, and production websites for Sri Lankan businesses — and I deploy them myself on Cloud Run, Compute Engine and self-hosted Coolify.
Most of my work starts with a real constraint: a tourism competition brief, a CCTV storage bill, a Sinhala font that breaks in a video renderer, a client who loses leads because nobody answers email. I like turning those constraints into small, well-documented systems that keep working after the demo.
On the infrastructure side I work container-first. Every project in this portfolio ships with a Dockerfile, most with docker-compose, and the larger ones with Cloud Build or GitHub Actions pipelines using keyless Workload Identity Federation. I self-host a Coolify PaaS on a Google Cloud VM for side projects and keep a public handbook of the Linux, Docker, Kubernetes, AWS and GCP labs behind it.
Outside code I'm Social Media Head at InFocus Media, Rajarata University's official media unit, an AIESEC member and a photographer — and I'd rather explain a concept in Sinhala than leave a classmate behind, which is why several projects here are bilingual learning hubs.
02Capabilities
What I can build for you
All case studiesSix disciplines, each backed by shipped work — 23 case studies in total.
AI agents & LLM systems
Multi-agent systems on Google ADK and Gemini, MCP tool integrations, and deterministic fallbacks so a model is never the only path.
DevOps, cloud & SRE
Container-first delivery with Dockerfiles, Compose, Cloud Build and GitHub Actions — keyless Workload Identity Federation, Cloud Run, Compute Engine and self-hosted Coolify.
Machine learning & vision
Computer-vision pipelines, deep-learning labs and analytics, carried from a notebook to a deployed API.
Full-stack products
Marketplaces, HR and inventory systems with real business rules, and production websites for Sri Lankan businesses.
Network engineering
Campus design with VLSM, VLANs and multi-area OSPF, built and verified in Packet Tracer with AI tooling around cisco-pt-mcp.
Design, media & tooling
Brand systems, programmatic video and Sinhala-first creator tools — plus developer tools that make other software easier to build.

06Principles
Decisions I stand by
How I thinkNora Labs, Tourthon 2026
Make the AI optional
Every agent endpoint falls back to a deterministic engine, so an outage degrades quality, never availability.
Quintrix ITSO
Keep a 72-hour grace period before deleting evidence
LOW-tier degradation is irreversible, so segments wait in a review queue where an operator can restore them.
InFocus SLUG 2025
Host the event site for zero cost
A results site that matters for one season doesn't need a monthly bill — free hosting with a sensible fallback plan.
