What I'm looking for

I'm looking to build scalable backend systems in a fast-moving startup environment, where I can own open-ended technical challenges, design reliable integrations and microservices, and contribute to architecture while mentoring engineers.

At Skupreme, I built and maintained backend services for marketplace and WMS integrations, order processing, inventory synchronization, and third-party API workflows. My work reduced API response times by 40%, deployment times by 50%, and integration time by 25%.

I've designed multi-tenant, event-driven microservices that handle 10K+ daily orders, connect marketplaces including Amazon, Shopify, and eBay, and keep inventory synchronized in real time. I enjoy fast-moving startup environments, taking ownership of open-ended technical challenges while collaborating with clients and mentoring junior engineers.
