builds AI systems and ships them to the cloud.
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.
01About
Engineer, builder, storyteller.
Read my storyMost 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.
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.

Courses
- 30 Oct 2026Zero-Cost Hosting for InFocus SLUG 2025 — and 25 Hosting & Domain Options ComparedWhy the university games results site runs for nothing on free hosting, what 'free' really costs, and a 25-option comparison including Oracle Cloud Always Free, Cloud Run, Vercel and .lk domains.
- 29 Oct 2026Cloud Run Problems I Actually Hit — and the Morning My Demo Was GoneMissing service accounts, region-locked models, disks that vanish, one-writer SQLite, schedulers that stop — and the build-time check that found Nora Labs returning Google's 404.
- 27 Oct 2026The $67.88 Lesson: What Two Trading Bots Taught Me About Automation61 real trades, a profitable_trades.csv full of test rows, and a bot that bought 182 times but sold 6 — why logs aren't outcomes, and the guardrails that replaced them.
- 25 Oct 2026Automation Did the Typing. Humans Did the Work.What automation genuinely saved across 23 projects — and the drawings, verification, font checks, hand calibration and Sinhala writing that only people could do.
- 23 Oct 2026Paying for Cloud as a Student: Budgets, Static Sites and a $10 PaaSBudget alerts first, static by default, the minimums that quietly bill you, load balancers vs Ingress, and running a dozen apps on one Coolify VM.
- 20 Oct 2026How I Ship 23 Projects: Cloud Build, GitHub Actions, Keyless Auth and CoolifyThe deployment map behind my portfolio — which project runs where, the real Cloud Build and GitHub Actions files, Workload Identity Federation, what tokenless PyPI publishing looks like, and five rules I now follow.
