About YashLab
YashLab (yashlab.me) is an independent engineering laboratory and tech publication founded by Yash. It serves as a living notebook for exploring distributed systems design, database connection pooling, high-throughput caching, and cloud cost optimization.
Every paper and guide is code-first, rooted in real production debugging, and backed by measurable benchmarks. No marketing hype, no corporate fluff — just honest engineering notes for builders.
