I’m an Android engineer with 13+ years of experience building scalable, high-performance applications, primarily in fintech environments like Revolut and OakNorth Bank. What sets me apart is my focus on both system-level architecture and user experience—optimizing performance, improving reliability, and delivering smooth, real-time interactions at scale. I enjoy solving complex engineering problems and working in collaborative, fast-paced teams. I’m currently looking for remote opportunities where I can contribute to building impactful, high-quality mobile products while continuing to grow in performance and architecture-focused roles.
