Seevali Rathnayake

Software Architect · Colombo, Sri Lanka · 16+ years in enterprise systems

I architect software in environments where it cannot fail — leading the modernisation of a large-scale enterprise platform across hundreds of .NET projects in a regulated industry.

Architecture is constraint management, not technology selection. Every system exists inside a web of pressures — business goals, team capacity, legacy debt, compliance, time. The job is navigating those constraints toward something that actually ships.

Building

Project What Stack
seevali.dev Signal feed — decisions, engineering notes, thoughts that earned their way out Astro 6, Cloudflare Pages
Nyx GPU-accelerated, privacy-first terminal with local AI Rust, wgpu, tokio
Kleos Voice-first web dashboard for a personal AI agent React 19, TypeScript, IndexedDB
Lyra Personal AI agent on NanoClaw — KB-aware, multi-channel Node.js, Claude Agent SDK

Three interfaces to the same brain.

Where I go deep

Brownfield modernisation — Nx monorepos, Strangler Fig, zero-downtime migration paths for large .NET codebases.

Performance engineering — Surgical bottleneck methodology. Fix only what blocks business outcomes, not everything.

AI-assisted architecture — Custom agents that encode architectural patterns into developer workflows. Make the tooling consistent, not the humans.

Regulated industries — Aviation MRO. Software where zero margin for error is not a figure of speech.

By the numbers

160+ .NET projects unified · 22 performance bottlenecks catalogued · 100+ Claude commands · 150+ Copilot agent definitions · 196+ knowledge base notes

The work speaks. Everything else is context.
