Summary
I’m a passionate and detail-oriented software engineer with over four years of hands-on experience building user-centric, high-performance applications across both web and mobile platforms. With a strong foundation in full-stack development and a natural curiosity for solving real-world problems through technology, I focus on crafting digital experiences that are intuitive, scalable, and impact-driven.
My approach combines clean architecture with thoughtful design, and I enjoy diving into complex business logic just as much as I do polishing user interfaces. I thrive in fast-paced product environments where innovation, performance, and maintainability go hand in hand. Whether it's working on complex transactional systems, improving developer workflows, or exploring new technologies in AI, I’m always looking to push boundaries and evolve alongside the tech I work with.
