About

The entity behind the contract.

I'm Piyush Mehta — senior software engineer based in Kitchener, Ontario. Prexa & Co Ltd. is my Canadian federal corporation, incorporated inMay 2025. It exists so procurement teams can contract with a verifiable Canadian entity instead of an individual — and so the work has a proper legal home.

I build systems that have to work in production, not just in demos. Enterprise AI workflows that respect compliance boundaries. Architecture that holds up under real load. Code reviewed for security before it ships. Six-plus years across energy, insurance, and professional services — measurable outcomes, honest communication.

Available on C2C contracts, remote or hybrid around Toronto.Available for new engagements — contact for a quote.

Contact

Bring me your hard problem.

If you have a concrete engineering question — an AI workflow that needs to pass compliance, an architecture decision, a codebase that needs securing — send it. You'll hear back with a real answer, not a sales funnel.
