Senior Engineer II @ Contentstack
Worked together on the same team • July 2022
I had the privilege of working with Hitesh for two years at Contentstack, where he was both a mentor to me and a leader for our team. During this time, he helped us grow from focusing on individual tasks to working together on bigger product goals. Hitesh is a natural leader with a strong sense of ownership. What makes him stand out is how he balances shipping new features with taking care of tech debt and engineering backlog—he knows both are equally important for long-term success. Throughout our work on multiple visual building products for the Contentstack CMS, Hitesh didn't just lead from the sidelines. He wrote code, pushed for good engineering practices, and ensured alignment across different teams. His hands-on approach combined with strategic thinking made him essential to our product's success. Any team would be lucky to have Hitesh's leadership, technical skills, and dedication to both people and product.
