Senior Software Engineer — Mobile (Flutter · React Native) + Backend (Node.js · TypeScript)

Durgesh Parekh

Senior Software Engineer | Flutter · React Native · Node.js

I design and build products from scratch. Over 8+ years I've been a founding engineer, led mobile teams, and delivered systems end to end for YC-backed startups and international clients across the US, UK, EU, UAE, and India — architecture, real-time systems (MQTT/IoT), backend services, and the mobile apps on top, through to App Store and Play Store release. I work with a product mindset — I've owned features from user discovery and workflow design through to release. I've also integrated AI APIs (OpenAI vision/OCR) into production features.

Currently open to senior mobile / full-stack remote roles & contracts.

Based in India (IST) — open to remote roles across US, UK, EU, and UAE; available immediately for remote, open to hybrid/onsite with sponsorship.
