How I Build Products and Systems
Technical, product-focused principles I use when designing and shipping features and systems.
UI principles
- Usability — Tasks should be obvious and low-friction. I prioritize clear hierarchy, consistent patterns, and predictable behavior over novelty. If a power user can stay in flow and a new user can succeed without a manual, the bar is met.
- Performance — Interfaces should feel instant. I care about load time, interaction latency, and perceived speed (skeletons, streaming, optimistic updates). I use budgets and metrics so “fast enough” is measurable.
- Accessibility — UIs should work for everyone. Semantic HTML, keyboard and screen reader support, and sufficient contrast are non-negotiable. I treat a11y as part of the design system, not a post-launch patch.
System principles
- Scalability — Design for growth in data, traffic, and team size. I think in terms of bottlenecks, sharding, caching, and async boundaries so we can scale horizontally instead of rewriting.
- Reliability — Systems should degrade gracefully and recover quickly. Retries, timeouts, circuit breakers, idempotency, and clear error handling reduce surprise. I optimize for MTTR and mean time to detect as much as uptime.
- Observability — Logs, metrics, and traces are first-class. I instrument so we can see what’s happening in production, debug without guessing, and plan capacity. Good observability makes every other principle actionable.
Tradeoffs and design decisions
I treat every non-trivial choice as a tradeoff: consistency vs. flexibility, speed to ship vs. long-term maintainability, build vs. buy, and so on. I document the decision, the alternatives considered, and what would make us revisit it. That keeps the “why” visible and makes it easier to change course when constraints change.
I prefer boring tech where it fits—proven patterns, well-understood stacks—and reach for newer tools only when the problem clearly benefits. I’d rather ship a simple, readable solution and iterate than over-engineer up front.
