At SmartBet / ABC Lab, I architect and deploy an iGaming platform serving 100k+ concurrent players with 99.9% uptime during peak hours. I built Dockerized microservices and GitLab CI/CD pipelines that cut deployment time by 50%.

I also optimized API response times by 30% through database query optimization and Redis caching, and integrated payment gateways handling $2M+ in monthly transactions. I mentor junior developers on Laravel best practices and scalable architecture.

Previously, at Ardshinbank, I led backend development for core banking modules serving 500k+ users and modernized a legacy Yii2 codebase. At Globbing, I developed an e-commerce platform processing 50k+ daily orders; earlier, I built Node.js cryptocurrency trading bots at World of Duty and delivered full-stack web projects at Blessed Solutions.
