• Led incremental decomposition of Rails monoliths into Go-based services, improving scalability without downtime.
• Achieved 99.95% availability in production systems handling millions of monthly requests.
• Improved p95 API latency by ~33–40% through Go concurrency, Redis caching, and SQL optimization.
• Built API-first architectures with clear contracts, versioning, validation, and idempotency.
• Delivered high-throughput REST APIs consumed by external partners (fintech / SaaS / internal platforms).
• Designed event-driven workflows using async workers, retries, and message-based orchestration.
• Established observability-first systems with metrics, structured logs, and tracing.
• Supported incident response and on-call workflows, resolving production issues under pressure.
• Reduced manual operations by 30–40% through automation and backend tooling.
• Built TypeScript dashboards and internal tools tightly coupled to backend APIs.
• Worked comfortably across Ruby, Go, TypeScript, Python, and Elixir, learning fast where needed.
