- Evaluate build vs. buy decisions with data
- Strong proficiency in TypeScript and Node.js
- Build high-throughput, low-latency microservices using frameworks like NestJS, Express, or Fastify

- Analyze production incidents: read logs, trace requests, identify root cause under pressure
- Think about failure modes before they happen (circuit breakers, retries, fallbacks, graceful degradation)
- Participate in on-call rotations and drive blameless post-mortems
- Proactively identify capacity risks and performance bottlenecks
- Identify risks, tech debt, and performance bottlenecks before they become incidents
- Propose and drive improvements - don't wait for a ticket
