Self-Hosted PostgreSQL 18 for Railway
A production-ready Postgres 18 template published when Railway had no official option, adopted by enough deployments to fully cover my own Railway usage.
notable work
Project notes, experiments, and engineering background.
A collection of software, embedded systems, and hardware projects that shaped how I think about practical engineering work.
Current works
What I've been building lately, from public templates to full-stack apps to problems I ran into around the house.
ATtiny85EmbeddedAutomotive
Factory-Style Cargo Bed Lights
An ATtiny85 controller that retrofits factory-look cargo bed lighting onto a truck that never shipped with it, down to the smooth fades and battery-saving timeout.
Next.jsSupabasePWA
Workout Tracker PWA
An installable, offline-capable web app that replaced the pencil and notepad I kept carrying around the gym, with proper development and production environments.
Earlier works
Past projects that have rotated out of the spotlight, kept here as the engineering background that still shapes how I work.
Addressable High-Power RGB LEDs
A hardware experiment scaling addressable LED behavior to higher-power RGB lighting with MOSFET control.
EmbeddedPWMHardware
Front-End Development Experiments
Earlier web work that marked the transition from simple interfaces into dynamic frontend systems.
