Backend Developer Intern at FPT Software Academy (2025-09 – 2025-12)

Co-designed and implemented backend microservices (5+ services) for a laboratory and blood-collection management system, covering sample collection, lab processing, and result management workflows.
Implemented an API Gateway using YARP as the single entry point, handling JWT authentication and routing requests to backend services — decoupling clients from internal service topology.
Built a dual-protocol communication layer — gRPC for latency-sensitive synchronous calls (e.g., fetching patient data to complete test orders) and RabbitMQ for asynchronous event broadcasting (e.g., publishing HL7 results to multiple services) — preventing cascade failures across the distributed system.
Implemented fault-tolerant messaging allowing the Instrument Service to keep processing blood samples when downstream services were unavailable, with queued messages reprocessed on recovery to ensure no loss of medical test data.
Applied CQRS with MediatR to separate read/write concerns, reducing handler complexity and making each operation independently testable.
