Systems over features: I design for long‑term maintainability and scale (clean boundaries, modular architecture, clear ownership).
Ship fast, ship right: I optimize for high iteration speed with CI/CD, automated checks, and strong monitoring.
Measure everything: I care about performance budgets, error rates, and deployment frequency — and use data to drive decisions.
