I’m a Senior Full Stack Web and Mobile Developer with 7+ years of experience building scalable SaaS platforms, enterprise systems, and real-time data-driven applications. I specialize in React, React Native, Node.js, and cloud-native architectures, with a strong track record of delivering high-performance systems used by over 1M users globally. I’ve led the architecture and development of large-scale platforms, improving performance by up to 45% and reducing infrastructure costs by 30%. My experience spans building microservices, optimizing APIs, designing robust database systems, and implementing reliable CI/CD pipelines with Docker and AWS. I’ve also developed cross-platform mobile apps and enterprise POS systems deployed across 1,000+ locations. Beyond core engineering, I focus on building systems that are scalable, maintainable, and aligned with business outcomes. I’ve integrated third-party services like Stripe and Twilio, improved API efficiency and database performance, and contributed to measurable business growth such as increased user retention and faster deployment cycles. I’m particularly interested in integrating AI-driven features and modern full-stack AI tooling into production systems, and I design architectures that are ready for real-time data processing and intelligent automation.
