Why I Built United Techlab
Legacy modernization is not a tooling problem. It’s a responsibility problem.
I built United Techlab after spending years inside complex enterprise systems where legacy code wasn’t just old, it was mission-critical, undocumented, and tightly coupled to business reality.
During my time working with Goldman Sachs (Compliance Division), a significant part of my work involved migrating legacy systems to modern technology stacks. These were systems no one wanted to touch, written in proprietary or outdated technologies, with business logic accumulated over decades.
What became clear very quickly was this: The hardest part wasn’t rewriting code. The hardest part was understanding what the system actually does, and ensuring nothing breaks.
The Problem I Kept Seeing
Across enterprises, the pattern was always the same: Systems built long ago by vendors like IBM, proprietary languages with shrinking talent pools, and heavy license fees.
Modern AI tools don’t work on these stacks. And “AI platforms” that promise automated modernization rarely survive contact with real enterprise code.
What enterprises actually need is engineering judgment, ownership of outcomes, and a pragmatic, incremental path forward.
From Platforms to Responsibility
Before starting United Techlab, I delivered systems for large enterprises and growing startups across the US and India. I realized that enterprises don’t need another platform, they need someone to take responsibility.
Why United Techlab Exists
We exist for enterprises trapped in vendor-locked legacy systems who want to exit without breaking the business. We don’t promise miracles. We promise engineering rigor, clear communication, and accountability.
