Software modularization, reliability & cloud migration
Building software systems that stay modular, reliable and modernizable. I'm Tuba Kaya. I help engineering teams untangle complex systems — decomposing monoliths into clean modules, hardening reliability, and moving legacy workloads to the cloud without stopping the business. This is where I write down what I've learned.
What I focus on System Modularization Decomposing monoliths and tangled systems into modules with clear boundaries, ownership and contracts.
System Reliability Designing for failure: SLOs, resilience patterns, observability and operable systems that stay up under load.
Cloud Migrations Moving workloads to the cloud pragmatically — the strangler path, not the big-bang rewrite.
Legacy Modernization Turning legacy liabilities into evolvable assets without halting the business.
Software Principles The durable ideas — coupling, cohesion, boundaries — that outlive any framework.

Why incremental replacement beats the rewrite, and how to route traffic through a facade while you carve a monolith into modular services.

Modularity isn't about file counts or service boundaries — it's about how much you must know, and change, to make a change. A practical model.
