Long-form technical writing on software architecture, infrastructure, AI, mobility and the operational questions behind technology.
A first-person field note on my merged NautilusTrader correctness contribution, an open Aroon performance RFC awaiting maintainer feedback, three SignrrGPT backend PRs, and the engineering lessons across both systems.
A first-person field note on why an overly rigid third-party verification journey became a product problem, and how I built document recognition around OCR, MRZ parsing, guided capture and address intelligence instead.
A production field note on tracing a receipt failure across different thermal printers, isolating the transport boundary and deploying one compatibility fix across a multi-branch operation.
