I build reliable backend logistics systems for high-volume inventory and orders.

What I'm looking for

I'm open to remote backend opportunities where I can build reliable systems that handle data consistency, concurrency, performance, inventory, and order-flow challenges.

At CenterSport, I build and evolve the WMS/OMS that replaced spreadsheet-based control across two distribution centers. It supports 50+ operators processing 2,000+ orders daily across 20,000 SKUs.

I'm responsible from data modeling through performance optimization, working with PostgreSQL under real concurrency and focusing on data consistency, inventory accuracy, and order flows.

I designed a multi-tenant architecture with isolated databases per unit and build asynchronous, event-driven integrations with RabbitMQ to decouple services and reduce processing failures. I use DDD to keep inventory rules clear and TDD with Jest to keep them reliable.

I prefer the unglamorous fix that eliminates phantom inventory and picking errors over a clever solution nobody asked for. I'm open to remote backend opportunities.
