About

I'm Janasundar, a Senior Software Engineer at Cimpress. My career has been defined by a transition from foundational roles at Cognizant to leading technical initiatives in the e-commerce space, where I focus on building performant, user-centric web and mobile experiences. I'm deeply passionate about developer experience and open-source; I've built tools like Luzo for API debugging and DevWiz for code transformation to solve real-world pain points. Whether it's optimizing Core Web Vitals to drive revenue or experimenting with complex React Native animations, I thrive on technical challenges that bridge the gap between clean code and business value. I’m always looking to connect with fellow builders to share insights on front-end architecture or gather feedback on my latest projects.

Opinions

  • API tools should focus on the dependencies between requests and multi-step flows rather than individual requests.
  • Web experiences must be performant, user-focused, and accessible.
  • Developer tools should prioritize simplifying workflows for both developers and QA teams.
