David is the engineering team’s performance specialist. If there’s a slow query, a memory leak, or an API endpoint that underperforms under load, he will find it and fix it. With a background in distributed systems from Carnegie Mellon University, he specialises in high-throughput API architecture, database query optimisation, and intelligent caching strategies.
In his time at AppsInfoway, David has reduced backend response times by 70%+ on three separate client projects — not by throwing hardware at the problem, but by understanding exactly what the system was doing and why. He is a core contributor to two open-source libraries used by thousands of developers: a PostgreSQL query analyser and a Node.js circuit-breaker implementation.
