Need 8+ years experienced full stack engineer
Vivek has delivered an exceptional performance working within the team. He was tasked with a highly complex charter: to reverse-engineer architectural sprawl, standardize reliability parameters, and create an operational baseline for the 55 setups serving some of our critical customer projects. Vivek not only executed these objectives to an excellent standard but also did so with great technical velocity by strategically leveraging AI tools. His work has successfully laid the groundwork to transition our engineering ecosystem from isolated, customized code forks into a scalable, productized framework.
