Engineering @ BrowserStack | Helping companies test applications across devices at scale

About

Software engineer, with a penchant to dive deep and explore systems. Currently working on Test Observability at Browserstack, to help provide customers better insights around thousands of test cases they run on Browserstack every day. Prior to Test Observability, I worked on Percy at Browserstack, which provided visual testing support for websites across desktop and mobile browsers. In an earlier life, I worked as a contract employee at Morgan Stanley, helping optimise their data pipelines to provide daily reports. During my college days, participated and conducted quite a few hackathons, which piqued my interest in software and led me on this fascinating journey. I enjoy working on open ended problems, exploring, analysing and tweaking codebases to help solve real world problems.
