Experiencia laboral

Senior Full-Stack App Developer

SwiftRank Solutions • Tiempo completo

Jan 2021 - Present • 5 yrs 4 mos

As a Senior Developer, I lead the end-to-end lifecycle of mobile applications for both iOS and Android platforms. My role involves translating complex business requirements into scalable technical architecture, managing API integrations, and ensuring high-performance user interfaces. - Designed and implemented robust app architectures using Flutter and React Native to ensure 99.9% uptime. - Developed and maintained secure RESTful APIs and WebSocket connections for real-time data synchronization. - Worked closely with design teams to implement pixel-perfect, responsive layouts that follow Material Design and Apple Human Interface Guidelines. - Conducted rigorous code reviews and implemented automated testing suites (unit, widget, and integration tests) to reduce post-release bugs. Key Achievements - Refactored the core rendering engine of the company’s flagship e-commerce app, resulting in a 40% increase in screen load speeds and a 25% reduction in battery consumption for end-users. - Successfully migrated a legacy monolithic backend to a serverless microservices architecture using AWS Lambda, allowing the application to scale from 10,000 to 500,000 active monthly users without service interruptions. - Developed and integrated a custom multi-tier subscription and in-app purchase system that led to a 15% growth in monthly recurring revenue (MRR) within the first quarter of deployment. - Introduced an AI-driven personalized notification system that increased daily user engagement by 35% based on behavioral data analytics. - Overhauled the application's authentication flow by implementing OAuth 2.0 and biometric encryption, which eliminated 100% of reported unauthorized access attempts over a 12-month period.
