What I'm looking for

I’m looking for a role where I can lead backend/API development and build cross-platform apps, delivering secure, resilient systems while mentoring teams and contributing to a strong engineering culture.

I’m a results-driven software developer with 5+ years designing and building scalable, high-performance backend systems, APIs, and cross-platform mobile applications. I’ve delivered 3+ production mobile apps and 5+ backend services, with a focus on secure, efficient, resilient solutions.

In my recent role as Team Lead at Softon Digital Limited, I led development of scalable, modular codebases using clean architecture and reusable components, improving development efficiency by 100%. I guided implementation of design patterns and API integrations across frontend and backend teams, mentored developers, and helped ensure pixel-perfect UI delivery from Figma designs across devices.

I’ve also built fintech-focused products, including salary advance and payment workflows, and strengthened mobile experiences through reusable Flutter components and real-time systems. From improving workplace focus by 50% in a salary advance solution to increasing user conversion by 15% and delivering real-time notifications, I bring a practical, team-oriented engineering mindset rooted in problem solving and continuous improvement.
