LAHIRU PATHIRAGE , COLOMBO, SRI LANKA, 2026

I build systems that think and scale. AI agents, serverless architecture, and the unglamorous infrastructure that holds them together.

What I build.

01

AI Agents

Building software that can plan, use tools, and finish multi-step work on its own. Not chatbots – systems that actually get things done, with very little hand-holding.

02

Serverless Architecture

Backends that scale from zero to millions, and only cost money when they’re actually working. Managed services where they save time, custom infrastructure where they get in the way.

03

Developer Tooling

The boring stuff that makes the interesting work possible – logging, deployments, and the day-to-day tooling that lets a team ship without breaking things.

Open to interesting problems.

I'm open to senior and lead engineering roles, and selective consulting on AI-agent architecture. The fastest way to reach me is by email.
