📐 Principles
Requirements first, architecture second, implementation third. Skip steps at your peril. Every architecture tells a story about the problem it solves.
There is no perfect architecture. I document trade-offs explicitly so future teams understand why decisions were made.
The best architecture is the one that can change. Loose coupling, high cohesion, clear boundaries, well-defined interfaces, feature flags.
If it isn't documented, it didn't happen. ADRs capture context and rationale. RFCs gather feedback before commitment.
The best tech stack is the one your team knows, your ops team can run, and will still be maintained in 5 years.
🧠 Mindset
I think in time horizons: what works today, what scales next quarter, what evolves next year, and what gets replaced in five years. I lead with questions, not answers. The best architects enable teams to make good decisions without them.
My methodology: C4 Model ? ADRs ? RFCs ? Sprint Planning ? Retrospectives. Every phase has a deliverable.
