• 🧭 Tech Lead at BinaryLab, leading delivery of a platform built with Next.js, NestJS and PostgreSQL
• 🧑‍💻 Previously frontend lead for two Mastodon-based social networks and engineer on products for Sheng Siong (Singapore) and Anicana, a Web3 platform (Japan)
• 🤖 All-in on LLM-assisted engineering, and building my own coding agent to understand the loop end to end

nexteditor.dev · source · TypeScript · 2,100+ commits

A browser-based recorder and replay engine for real, multi-file coding lessons. It captures the whole workspace — editor changes, live preview, terminal, HTTP calls, slides, captions, audio, even the instructor camera — and replays everything from a single timeline. Recordings stream as .ne files that start playing before they finish downloading, and Yjs-powered live rooms with voice chat make lessons collaborative. Built with React 19, XState, Monaco, WebContainers, a Rust→WebAssembly diff codec, and Cloudflare Workers.

🎬 Its Studio is an AI lesson-production pipeline inside the editor. A director compiles authored scripts into deterministic performances — typing the code in the real editor, highlighting exactly what the narration explains, running it live — with in-browser TTS narration reviewed by an editorial critic. Every render must pass mechanical QA and a two-render repeatability check before a human reviews and publishes it.

📝 Write-up: I Built an Interactive Code Recording Engine with XState Instead of Recording Videos

github.com/channyeintun/nami · Go

An agentic coding CLI powered by LLMs — think, plan, and execute code changes without leaving the terminal. A Go engine drives the agent loop, tool execution, and permission gating; a custom TUI (Silvery) streams the session; and plans, task lists, and walkthroughs persist as first-class, reviewable artifacts. Works with Anthropic, OpenAI, Google, DeepSeek, Groq, Mistral, Ollama, and GitHub Copilot.

source · Next.js 16

A fast Mastodon web client with real-time streaming, chat-style DMs, PWA push notifications, a Wrapstodon year-in-review and 10 languages including Burmese. Built with React 19, TanStack Query and deployed on Cloudflare via OpenNext.

kite-lang.dev · source · Rust

A statically compiled language for WebAssembly. Most of the work goes into keeping it small enough to read: few keywords, no hidden control flow, errors you can't ignore by accident. The compiler, kitec, is written in Rust.

35+ articles in English and Burmese on my GitBook. A few favourites:

• The Anatomy of an Agent Harness
• Harness Engineering: How to Build Software When Humans Steer, Agents Execute
• XState Under The Hood
• JS Closure Memory Leaks
• Memory Alignment in Go
• Web Accessibility

Most of my work now starts as a prompt, a plan, and a review. The agents I actually keep open:
