I build high-performance Laravel and NestJS APIs for fintech, Web3, and streaming platforms.

I've built backend systems for SMARTSOFT's payment-terminal CRM, Holiverse's Polygon-based Web3 platform, and TREBEL Music's high-traffic streaming service. My work includes real-time device tracking, transaction processing, NFT and social-platform APIs, offline downloads, user libraries, and asynchronous processing with RabbitMQ.

I use PHP/Laravel and Node.js/NestJS to create clean, scalable services, with a strong focus on database optimization, distributed systems, and reliable API integrations. Across products including Loxala and Aloft AirControl, I've worked with MySQL, PostgreSQL, MongoDB, Redis, Docker, AWS, and RESTful APIs.
