Focus & Philosophy
I approach engineering as a balance between building things well and keeping them running well—design, performance, and production reliability all matter.
Product-Minded Engineering
Contributed to evaluating and selecting Next.js for a legacy ASP.NET migration at CDI Credit, then implemented the frontend components and owned the responsive-testing pass before release.
Systems & Architecture
From a bitmask-based Tic-Tac-Toe engine to a modular Next.js portfolio built on App Router, I default to structures that make the next change cheap, not just the current one work.
Production Reliability & Support
Production incidents don't get resolved by luck — they get resolved through structured root-cause analysis and escalation workflows I designed and standardized, plus documentation written so the next person didn't have to solve it from scratch.
Skills
A toolkit split the same way the work is: building things, and keeping them running.
