Hi, I'm Jun Chen — a senior backend engineer with 10+ years building distributed systems, data platforms, and cloud infrastructure. Most recently shipped Go REST APIs for an IoT smart-lock platform at Janus International (Noke), with deep experience in functional programming (Go, Scala), real-time streaming at 300K events/sec, and cloud tooling (AWS, Terraform, Kubernetes). The projects below are what I build outside of that: real, running software, not case studies.
$ ls /usr/lib/skills/*
Languages/ Python, Rust, Go, Scala, Java, TypeScript, SQL, Shell
Backend/ REST APIs, microservices, Spring Boot, Akka
Cloud & Infra/ AWS, Terraform, Docker, Kubernetes
Data/ MySQL, PostgreSQL, MongoDB, Redis, Spark

A modal editor proved correct against Emacs, 2,000+ differential cases.
A magit-style TUI for git — one status buffer, folded from sections to hunks.
A magit-style TUI for system ops — a healthy machine produces a nearly empty screen.
