Jason Ray Acido

I'm a full-stack software engineer with 7+ years of experience shipping production SaaS as a primary developer. I specialize in React, TypeScript, and offline-first architectures, and I've spent the last 4+ years building two EdTech platforms end-to-end for a long-term contract client. My most technically demanding work has been architecting a React 19 monorepo (13 internal packages) powering a publishing platform for educators. It features Canva-like drag/resize/rotate canvas manipulation running at 60fps, a plugin-based generative content engine for worksheets and puzzles, and WASM-compiled Zstandard compression with IndexedDB persistence for offline-first resilience. On the earlier version of the platform, I contributed 3,238 commits over 5 years as the primary developer (51.5%), building 55+ educational tools including a multi-variant Sudoku engine with parallel Web Worker generation. Beyond client work, I build ambitious personal projects: an offline-first finance PWA with event sourcing and vector clocks, a full-stack resort booking system with RBAC and 220 test files, and an MCP server extending Claude Desktop with local tool integrations. My stack centers on React 19, TypeScript, TanStack (Router/Query/Table/Virtual), Tailwind CSS, Supabase, and Node.js. I'm comfortable across the full stack, from PostgreSQL migrations and RLS policies to Cloudflare Workers and GitHub Actions CI/CD. I'm looking for a senior or lead remote role where I can own features end-to-end, ideally at a product company that values craftsmanship and async-first collaboration. I've been working remotely from the Philippines (GMT+8) since 2020 and thrive in autonomous, high-trust environments.
