What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my skills in mobile development to create impactful applications while continuing to grow professionally.

I am a dedicated Software Engineer with a strong passion for iOS and Android development, boasting extensive experience in the native apps ecosystem. My focus lies in delivering excellent, accessible user experiences (UI/UX), guided by SOLID principles and clean code architecture. I am driven to get things done and deliver high-quality solutions without compromising the integrity of the code base, project architecture, or app performance.

Throughout my career, I have successfully designed and implemented system architectures that integrate mobile applications with cloud backends, enabling seamless communication with peripherals through BLE technology. I take pride in mentoring junior developers and leading teams to exceed user and stakeholder expectations through end-to-end testing, accessibility, and impeccable code quality. My ability to coordinate design, development, and QA tasks has consistently resulted in the timely delivery of projects.
