I help businesses design and launch reliable Android apps that work anywhere — even on low-end devices and in low-connectivity environments. With 5+ years in software engineering and 4+ years building and publishing Android apps, I’ve worked with companies serving 1.5M+ daily active users and with startups bringing their first product to market. I focus on translating complex requirements into clean, scalable code for sectors including fintech, insurance, supply chain, energy (oil and gas), and e-commerce. From offline-first workflows to multi-language support and data-driven product improvements, I deliver solutions that drive adoption and measurable results.
Over the past five years, I’ve worked on Android projects that have increased operational efficiency, improved user engagement, and boosted conversion rates — in some cases by up to 30% within eight months. These results came from focusing on the right features for the right users, using insights from user interaction data and in-app analytics to guide decisions. By identifying friction points in the user journey and adapting the UX — such as refining onboarding flows, optimizing call-to-action placement, and testing different layouts — I’ve been able to align product design with actual user behavior.
My approach blends A/B testing, dynamic UI experimentation, and analytics-driven decision-making to uncover the root challenges behind a business goal. I then design practical, scalable Android solutions optimized for performance, reliability, and long-term maintainability. I’m at my best when solving complex problems, simplifying user experiences, and collaborating with teams to deliver results that last.
