What I'm looking for

I'm looking to lead and build scalable mobile and web applications, improve architecture and performance, and mentor developers while delivering user-focused products.

I've led Flutter teams at ByteSigmaTechnologies, improving project delivery efficiency by 30% through workflow optimization, code reviews, and structured development practices.

I architect scalable mobile and web applications across healthcare, e-commerce, and finance, with clean architecture, reusable modules, and performance-focused development. Previously at Dars Innovations, I improved application responsiveness and load times by approximately 25% and built the Filoo marketplace with Mangopay payments.

I've delivered more than 40 Android applications for international clients at BrainMobiTechnologies, including the Ideal Smart healthcare platform integrating Bluetooth devices, Google Fit, Firebase notifications, and real-time communication. I also enjoy mentoring developers and improving engineering quality.
