I share practical software engineering lessons from real work—and document building software products and startups as a solo founder.

The channel covers backend and product engineering: APIs, Go, Rust, TypeScript, frontend/full-stack systems, databases, architecture, infrastructure, AI-assisted development, performance, reliability, and the trade-offs behind shipping real products.

Expect concrete comparisons, implementation details, benchmarks, debugging lessons, architecture decisions, product experiments, validation results, launch lessons, and founder decisions grounded in real work.

Backend remains the technical depth anchor, but the goal is broader: use the right tools to build, launch, and operate real software products.
