I've built and owned Rola Competition Platform's admin console, backend APIs, payment stack, voting engine, and analytics at Crystal Vision. As the sole developer of the 34-module Next.js admin console and primary NestJS backend developer, I enabled operations teams to manage competitions without engineering support.
I also built a Laravel affiliate and payout portal with automated approval workflows and reusable data masking, plus AI-assisted logistics and full-stack fitness platforms. I work across TypeScript, React, Next.js, NestJS, Laravel, payments, role-based access, testing, and production guardrails.
