About Me

Hi, I'm Hanushka 👋

I'm a mobile engineer specialising in iOS and Flutter development, focused on building scalable, high-performance mobile applications with clean architecture and intuitive user experiences. I enjoy working at the intersection of engineering, product thinking, and user experience, where well-crafted interfaces meet robust, maintainable code.

Currently, I'm a Senior iOS Engineer at TMC, where I work on Mileage+, a platform designed to simplify mileage tracking and expense management. One of my key contributions has been engineering the Auto-Track algorithm, which processes 10k+ trips per month with 95% accuracy, while also helping reduce API response times by 40%.

Over the years, I've worked across different organisations and product environments, building native iOS and cross-platform mobile applications. Along the way, I've also had the opportunity to mentor developers, lead code reviews, act as Scrum Master, and help define engineering standards, experiences that have shaped how I approach building scalable and maintainable mobile products.

Outside of engineering, I enjoy photography, exploring new places, and keeping up with emerging technologies in the mobile ecosystem.
