Experience
SunoStudios
https://sunostudios.com/SunoStudios connects musicians with recording studios and helps them book recording time. I developed and managed the website powering the platform. One of the biggest things I learned while building a product-based company was how to navigate SEO challenges and become the top-ranking website on Google. I optimized the site's content for keywords and phrases like "best-recording studios in Bangalore" and "best-recording studios near me." The website still ranks high on the first page for such search terms.
Mobile Satyagraha Application
An Android application for the volunteers living in cities to connect to CGNet Swara and help them in their mission. Users can view the problems posted by people living in rural areas and adopt them to work on them. The application allows multiple volunteers to assume the problem and comment in a forum-like structure on the progress of the solution.
Yatra Application
An application for the Yatra team of CGNet Swara to use when working in remote areas with no internet connection. The application stores the information about the people the team trains offline and then syncs it with the central database when they get the network coverage. The synced details are verified against the data collected by CGNet Swara on their public-facing channels, which helps track user acquisition and employee performance.
