Notes fromthe build.
Lessons, experiments, and useful mistakes from building software, understanding systems, and learning one layer at a time.
Featured note
How to integrate the Spotify Web API with Next.js
A practical Spotify Web API and Next.js guide covering OAuth, refresh tokens, currently playing data, secure Route Handlers, polling, rate limits, and compliant UI.
What a telemetry dashboard taught me about resilient interfaces
Building live coding, GitHub, and Spotify signals into one portfolio changed how I think about loading states, partial failure, and honest interface design.
Design tenant boundaries before automation writes data
What DayBoard taught me about identity-derived scope, defence in depth, and why multi-tenant safety has to precede booking automation.
Real-time software changes when physics joins the system
Lessons from an ESP32 flight controller about task rates, coordinate frames, saturation, failsafes, and debugging software attached to hardware.
Enterprise software is a problem of state and ownership
Building EITAMS showed me why custody, financial rules, concurrency, and audit history matter more than the number of forms in an internal platform.
