Food Discovery Platform
Live · Play / App Store Personal Product

Savordex is a location-based food discovery app I built from the ground up, fully ideated, designed, developed, launched, and grown by our Team. It lets users discover restaurants and food spots nearby with rich multimedia reviews, geolocation-powered listings, and real-time content.

I wasn't just the developer, I was the product owner, team lead, and growth driver. I assembled and led a lean team, coordinated digital marketing campaigns, and kept the platform live with zero compromise on data security for all users.

Built, launched and scaled from idea → production → 5,000+ users while leading product, engineering and growth.
