Talks I've given.
Conference talks on architecture and engineering — patterns, pitfalls, and what actually works in production.
Modularize before you migrate: maximizing ROI on a monolith-to-microservices move.
A personal story of leading a backend migration — why most teams start the migration too early, and how to de-risk it by modularizing the monolith first.
