Atsushi Oka (Ats) — Full-Stack Engineer | Developer Tooling | TypeScript/Node/PostgreSQL
I build systems that last: web application frameworks, automation tooling, and documentation/publishing pipelines. I care about explicit design, readable code, and architectures that remain maintainable after years.
English is my second language; some wording may be AI-assisted.
What I do
- Build full-stack web applications (API + DB + UI) with TypeScript/Node.js/PostgreSQL
- Design internal platforms (routing, auth, job pipelines, config/deploy, tooling)
- Ship practical frontend features in React, including performance-oriented UI patterns (e.g., infinite scrolling)
Proof (projects)

Technical strengths
- Backend / Data: Node.js, TypeScript/JavaScript, PostgreSQL, Linux/systemd
- Frontend: React (incl. infinite scrolling), TypeScript
- Tooling / Writing: GitHub Actions, Quarto + Obsidian workflow, automation scripts
- Languages: TypeScript/JavaScript, Java, Scheme (Guile/Kawa), Perl, Delphi (Object Pascal)
- Legacy / Migration: experience porting host/legacy systems to Unix server environments
- Dev environment: Neovim, tmux; daily Linux user (Ubuntu since 9.04)
AI-augmented development (how I use AI)
- Use AI as a pair programmer with explicit constraints and review-first workflow
- Prefer interactive, inspectable workflows (often via web UI) over blind code generation
- Verify outputs with tests, small patches, and security-conscious checks (no copy/paste execution of untrusted code)
