I’m Mridul Halder, a Full-Stack Software Developer with 3+ years of hands-on experience building production applications using Flutter and a modern backend stack. I started as a Flutter intern at Supernova Techno Limited in July 2023 and became a permanent team member in January 2024, where I’ve delivered healthcare, HRM, and POS solutions end-to-end—from REST APIs and authentication to admin/web interfaces and mobile features. I’m especially interested in building reliable, database-driven systems and integrating real-world capabilities like real-time video consultation with Agora RTC and background location tracking on Android.
