Built and owned backend microservices for biometric authentication and digital identity workflows in .NET and ASP.NET Core for government and enterprise use cases. Migrated inter-service communication from REST to gRPC and Protocol Buffers, reducing internal response time by roughly 40–60% and cutting network overhead by about 33% through binary serialization instead of text/base64 payloads. Developed face and fingerprint authentication services for 1:1 and 1:N matching using Neurotechnology SDKs and Milvus Vector DB for nearest-neighbor search and deduplication. Implemented asynchronous event-driven workflows with Kafka, RabbitMQ, Redis, multithreading, and task-based async processing for scalable backend execution. Designed and maintained internal PKI services supporting RSA/ECC certificate issuance, digital signatures, API validation, authentication middleware, rate limiting, and exception handling. Applied Clean Architecture, CQRS, MediatR, and Entity Framework Core; handled database schema design, indexing, Docker Compose, Nginx, Linux VMs, caching, queueing, and deployment. Wrote NUnit tests for core services and refactored PAdES PDF signing workflows from Java to .NET, reducing signing latency by roughly 20–30% while making the flow local to the service.
