Software engineer writing about systems, security, and the code behind them.

I write about backend architecture and the practical decisions behind shipping production systems — authentication and security patterns in NestJS, AI model integration, and lately Solana-based fintech infrastructure. More to come. Mostly notes from things I've actually built and broken, not theory for its own sake.
