Welcome to Kaushik’s Bits & Pieces
Who I Am & Why I’m Writing
I’m Kaushik Iska — software engineer, YC-founder, CTO of PeerDB (acquired by ClickHouse), ex-Flutter contributor, and parent to energetic twin toddlers. Over the years I’ve filled private notebooks with database oddities, GPU experiments, and performance war stories. Friends kept nudging me to put the interesting bits somewhere public.
Why now? Honestly—why not now? The infrastructure world feels especially exciting: lot of changes and lot more momentum in every area of software development. I have a backlog of side projects I want to talk and share about.
What to Expect
Architecture case notes from PeerDB, ClickHouse, and weekend side projects—including the dead ends and rollbacks.
Deep-tech essays on Postgres internals, golang oddities, GPU pipelines, distributed tracing, and the small algorithmic tricks that turn works into fast.
Reflections on balance: building systems while raising twins and staying (mostly) sane.
I’ll post roughly once a month. Rather than dumping raw code, I’ll focus on the thought process—trade-offs, mental models, and lessons learned.
See you in the next piece,
Kaushik
