Most developers write code. I help startup founders build products they can actually launch, grow, and show to investors. I have shipped 15+ products for international clients across the US and Europe, including Ambiently (real-time Flutter and Supabase MVP, live on TestFlight in 6 weeks), Hayakom (cross-platform tourist booking app), and JobDriver ai (AI SaaS platform with OpenAI, Stripe, and user dashboards). My fastest MVP went from brief to TestFlight in under 6 weeks. I maintain a 100% Job Success Score because I treat every project as a long-term partnership, not a one-time task. If you have been burned by developers who disappear mid-project, deliver sloppy code, or go quiet when things get complicated, that is exactly what I have built my reputation against.

Most mobile apps fail not because of development but because they lack scalability, performance, or real user value. I develop cross-platform mobile applications using Flutter and React Native, building for both iOS and Android from a shared codebase while integrating native modules whenever required. The projects industries I've worked on include healthcare, productivity, fintech, edtech, wellness, and real estate. Over the past few years, AI has naturally become a major part of the products I build.

Hi! I am Saurav. Most of my projects cover the full stack development - a Flutter mobile app, a React web app and dashboard, and a Node.js/Python-based backend, a complete one-stop solution for end to end delivery. Clients find it easier than coordinating three separate developers. 𝟵𝟲% 𝗝𝗼𝗯 𝗦𝘂𝗰𝗰𝗲𝘀𝘀. 𝗧𝗼𝗽 𝗥𝗮𝘁𝗲𝗱 𝗣𝗹𝘂𝘀. $𝟯𝟬𝟬𝗞+ 𝗲𝗮𝗿𝗻𝗲𝗱. 𝟴𝟬+ 𝗽𝗿𝗼𝗷𝗲𝗰𝘁𝘀 𝗱𝗼𝗻𝗲.
