# Mahesh Singh Sawant > Software Engineer at Meta Location: San Francisco, California, United States Profile: https://flows.cv/maheshsinghsawant As a frontend software engineer with over 7 years of experience, I specialize in collaborating with cross-functional teams to develop and deploy web product features, run A/B UI experiments for user growth, and design scalable frontend architectures and systems. I have expertise in using Javascript, Typescript, React, React-Native, Node.js, CSS, Scala, and other front-end/full-stack technologies to create responsive, performant, and accessible user interfaces on web, desktop and mobile applications. I've had an exceptionally well-rounded professional experience so far, beginning at a start-up (Upthere) that was eventually acquired by a major corporation (Western Digital) and then transitioning to a high-growth, fast-paced company in Twilio. More recently, at Grammarly, I collaborated with product and marketing teams to run multiple A/B experiments to test new features, designs, and strategies which helped greatly with new user acquisition and retention. Along with implementing a complete brand refresh for the entire website. Throughout my career so far, I've had the pleasure of working on some great products with incredibly talented individuals. ## Work Experience ### Software Engineer @ Meta Jan 2025 – Present | San Francisco Bay Area ### Founding engineer @ Grepr Jan 2024 – Jan 2025 | San Francisco Bay Area ### Software Engineer @ Grammarly Jan 2022 – Jan 2024 | San Francisco Bay Area ### Senior Software Engineer @ Twilio Jan 2022 – Jan 2022 | San Francisco Bay Area Led the entire front-end development cycle, from technical system design to product beta-launch, of a project to enable voice-calling in the Twilio Frontline app. The app was developed using React-Native with Twilio Voice SDK integration and featured at Signal, Twilio's annual conference.
