building edge-first systems, security tooling, and oddly useful open-source things
I'm Yasoga, based in Colombo, Sri Lanka. I like the part of software where product engineering, infrastructure, and security all meet: clean APIs, boring deploys, useful logs, and systems that do not panic the moment they touch production.
At the moment, most of my work sits around Cloudflare Workers, TypeScript, Hono, serverless storage, CI/CD, and security-minded architecture. I also build open-source tools when I hit a problem that feels annoying enough to deserve a package, CLI, or tiny protocol-shaped thing.
├─ role: Independent Technical Contributor @ BitByBit
├─ study: BEng Computer Networking & Cloud Security
├─ default runtime: Cloudflare edge
├─ comfort zone: TypeScript, Rust, APIs, infra, security tooling
└─ weakness: turning "small scripts" into published packages
| lane | current stack | why it stays |
|---|---|---|
| 🟧 edge runtime | Cloudflare Workers, Hono, Wrangler | low-latency APIs, deploys without ceremony |
| 🟦 data plane | D1, R2, KV, PostgreSQL, MinIO | SQL when it matters, object storage when it scales |
| 🟪 application layer | TypeScript, Next.js, React, Tailwind, Astro | typed product work without losing velocity |
| 🟩 delivery layer | GitHub Actions, Docker, BetterStack | repeatable deploys, visible failures |
| ⬛ systems languages | Rust, Python, C#, JavaScript | CLIs, audits, automation, and legacy rescue work |
