I am a highly skilled Flutter mobile developer with over 5 years of experience, adept at building high-performing, scalable, and secure applications for startups and enterprises alike. My work spans multiple industries, including fintech, retail, logistics, and energy, where I tackle some of the most challenging and technically demanding projects to deliver innovative, business-critical solutions.

At Gap Inc., I was responsible for building mobile application for —GAP— a major global brand under aggressive deadlines and high-performance expectations. I handled end-to-end project architecture, designing complex, scalable features like multi-language localization, which led to a 25% increase in user engagement. Additionally, I led a comprehensive overhaul of the app's security infrastructure, implementing protocols like PKCE and jailbreak detection, ensuring zero security breaches. Managing a team of engineers, I integrated Contentful, enabling dynamic content updates without the need for app releases, which improved user personalization and boosted session times by 20%. The high demand for feature rollouts and scalability forced me to optimize both the development pipeline and app architecture, ensuring timely delivery without compromising quality.

At Pfund Mobile, I faced one of the most technically challenging projects of my career. I was tasked with developing an offline peer-to-peer transaction system, requiring both speed and airtight security. I engineered an offline authentication mechanism using Elliptic Curve Digital Signature Algorithm (ECDSA), enabling seamless transactions without internet access. The process required deep cryptographic knowledge and understanding of secure key exchange protocols. I also developed a robust security mechanism to prevent unauthorized wallet spending by implementing Profile Image Bound Identity Verification (PIBIV), an image hashing technology used for fraud prevention. The project demanded overcoming significant hurdles related to offline synchronization and secure transaction flows, which I successfully addressed while maintaining system integrity.

At RouteLift, I led the development of a next-generation logistics application that pushed the limits of mobile solutions. I built complex features like real-time tracking, OAuth authentication, and asynchronous messaging in a highly distributed architecture. I architected the app to support multi-point delivery routes, solving critical challenges around scalability, data synchronization, and low-latency performance. By implementing GitLab CI/CD pipelines, I automated daily production deployments, reducing the time-to-market by 20% and significantly improving operational efficiency.

In all my roles, I balance rapid feature development with maintaining high-quality, testable, and scalable code, delivering mobile solutions that excel under real-world pressures.
