I've built and architected mobile and web applications across Arogga, Circle FinTech Ltd., Advanced Apps Bangladesh, and Netexpro.
At Arogga, I architected the Android and iOS front end, reduced crash- and delay-related complaints by 30%, and used Redux to improve responsiveness and stability. I collaborated with a five-person team to launch three mobile applications in six months, helping achieve a 25% faster time-to-market.
At Circle FinTech, I worked on SaaS and financial-services software using React.js, React Native, TypeScript, NestJS, GraphQL, Docker, and clean coding practices.
Earlier, I increased user engagement by 30% at Advanced Apps Bangladesh through a new feature and integrated payment gateways including PayPal, Paytm, Razorpay, Molliepay, Paystack, and Byan Pay. At Netexpro, I optimized user interfaces to reduce page load times by 40%.
