At Fantasy Space, I built and maintained backend services, APIs, and real-time functionality for SaaS and other products. I also designed microservices and event-driven workflows, and built product features with React, Next.js, Vue.js, and Nuxt.js.

At Teamwork.com, I developed backend services and business logic for production SaaS applications, improving reliability with caching, retries, and monitoring. Earlier, at YOLO, I built services and APIs for web and mobile applications and contributed to frontend features and production support.
