About

I'm Zero Kelvin — a senior software engineer with 8+ years of experience building production systems across blockchain, full-stack web, and cloud infrastructure.

My most significant work has been at Hawksight, where I spent four years as the Solana Blockchain & Backend Engineer. I authored two production smart contracts with a deliberate security-split architecture, built and maintained a TypeScript SDK for DeFi liquidity management, designed a custom Solana testing framework, and built the backend REST API serving 50+ endpoints with Redis caching and real-time position analytics.

Before that, I worked across the stack at Simplex Internet as a Software Engineer and SRE — Kubernetes, CI/CD pipelines, security audits, and multiple Laravel production apps. I also spent time at Optimy and Canow, contributing to grant management platforms and Cosmos/Tendermint blockchain infrastructure.

I build things that work. I care about correctness, clean architecture, and shipping.
