About
EconomiCS: The Economics of Computing. I view backend systems as resource-allocation problems and optimize them for latency, throughput, and cost. I focus on diagnosing bottlenecks in databases, caching layers, and service design, and making design decisions under real production constraints and load. Built production systems handling 5K+ RPS with sub-150ms p99 latency.
