Abhinav Tiwari

Database Consultant

The person behind your databases

I'm Abhinav — a database consultant with 12+ years of experience keeping production databases fast, available, and out of trouble. I've spent my career deep inside SQL Server and PostgreSQL, solving the kinds of problems that wake teams up at 2 AM.

Before going independent, I worked in enterprise environments managing databases for healthcare, logistics, and financial services companies. I've tuned queries on 45TB+ databases, migrated legacy systems across platforms, and built high-availability architectures that actually hold up under pressure.

I went independent because I kept seeing the same pattern — companies paying for large teams and expensive tools when what they really needed was one experienced person who could diagnose the root cause and fix it. That's what I do. No layers, no handoffs. You talk to me, I fix it.

When I'm not troubleshooting production fires, I write about database internals on this blog and explore new technologies like TimescaleDB. I believe the best DBAs never stop learning — the engine changes, the cloud changes, the problems evolve, and you need to evolve with them.

Outside of work, I'm a father to a curious one-year-old who has her own ideas about what my keyboard is for, and a husband to a wife who makes everything else possible. We love exploring new places together — weekend trips, hidden cafes, wherever the road takes us. It keeps the mind fresh and the perspective wide.

I'm also a reader. Ikigai taught me that purpose lives at the intersection of what you love, what you're good at, and what the world needs — and that's exactly how I think about my work. Deep Work by Cal Newport shaped how I approach complex performance problems — distraction-free, focused blocks where the real breakthroughs happen. Atomic Habits by James Clear reminded me that consistency beats intensity, whether it's blogging, learning PostgreSQL, or building a consulting practice. And The Almanack of Naval Ravikant gave me the conviction to bet on specific knowledge and leverage rather than trading time for money.

Performance Tuning

Migrations

What people say

Don't take my word for it — here's what my clients have to say.

Abhinav is one of the most talented SQL Server optimization people I have encountered in my career. He has a genuine drive to continually seek knowledge and improve his understanding of not just SQL Server but other RDBMS platforms as well as cloud native DB PaaS solutions.
