Full-Stack Software Engineer

Open for work · Remote

I build full-stack web applications, developer tools, and distributed systems — from fintech platforms to real-time and on-chain products. 7+ years shipping production software across fintech, SaaS, and Web3.

About

A Software Engineer from the Philippines with 7+ years building full-stack web applications. I specialize in React, TypeScript, and Node.js — with deep fluency in Linux, self-hosted infrastructure, and DevOps.

Years of daily-driving Arch Linux shaped a love for working close to the metal — terminal workflows, Docker, CI/CD pipelines, and cloud deployments. I've shipped everything from serverless APIs and fintech platforms to real-time trading systems and live-streaming infrastructure.

Lately I've been building open-source developer tools — Neovim plugins, CLI formatters, and AI-agent extensions. Driven to own systems end-to-end — architecture, API design, deployment, and observability.
