Jay Gajjar

Senior Software Engineer · Laravel, PHP and MySQL · WordPress and SEO

Summary

I build the back office: trading platforms, multi-company ERPs, and the integrations that connect them to the systems a business already runs on.

I joined Precise Developers in Ahmedabad as an intern in January 2023 and became a Senior Software Engineer in under three years. Most of my work is PHP 8, Laravel and MySQL.

What I care about most is data that stays correct under pressure: transactions and row-level locks so two people never get the same invoice number, and idempotent jobs so a retry never runs an operation twice.

Today I lead one or two junior developers, review their pull requests, and work with clients directly, from the first requirement to production support.
