At b_labs, I build microservices for a large-scale e-commerce platform and contribute to architectural decisions across retail services.
I developed a notification service sending over 150K messages daily and a secure user identity service supporting service-to-service authentication, phone-number login, OAuth, and OTP integrations. I also designed an event-driven internal service orchestrator that replaced legacy endpoint-based flows to improve scalability, fault tolerance, observability, and reliability.
I led the architecture and implementation of a financial user balance service for sales, returns, compensations, and penalties, with retry and consistency mechanisms for financial accuracy and auditability.
Previously, I developed Python and Django RESTful APIs at Orange Business and led internal portal and freelancing-platform development at WeCodeForYou using Node.js, Express, MongoDB, Docker, and AWS.
