Over nearly 3 years on Fiverr, Upwork, and Freelancer.com, I delivered web solutions for international clients while growing from frontend implementation to full-stack development & Graphic Design. I managed 50+ projects end-to-end — spanning responsive websites, React interfaces, WordPress and Shopify stores, and custom PHP/MySQL applications.

Full Stack Developer

PLAYGround Digital • Full-time

Jan 2023 - Dec 2025 • 2 yrs 11 mos

Promoted to lead full-stack development, I took ownership of scaling the backend infrastructure and driving the platform's transition from a monolith to a modern microservices architecture. I built complex business logic and high-performance APIs using PHP and Laravel, containerized services with Docker, and implemented Kafka for event-driven messaging alongside Redis for caching. I also worked across polyglot services involving Java Spring Boot and Python, while continuing to oversee the React/Next.js and React Native frontend to ensure seamless integration with the evolving backend.
