Hi, I'm Sifat Hasan
Senior Flutter Developer with 5+ years crafting high-performance, beautifully designed mobile apps — blending innovation, scalability, and precision in every line of code.
About Me
Engineering mobile products that scale.
I'm a Senior Flutter Developer with 5+ years of experience building production-grade mobile applications for enterprises, fintechs, and high-growth startups across Bangladesh and beyond.
My focus is on shipping cross-platform apps for Android and iOS that feel native, perform flawlessly, and scale gracefully — backed by clean architecture, robust state management, and thoughtful API design.
From HR platforms and sales-force automation for Samsung and Unilever, to fintech and edtech products serving thousands of users, I bring a product-building mindset: I care about the business outcome, not just the code.
