Architected a distributed event-driven backend using Apache Kafka and consumer groups enabling horizontally scalable, asynchronous processing with at-least-once delivery semantics and safe offset management. Engineered a concurrent Go worker engine with CPU-aware pools, bounded queues, structured retries, DLQ routing, and Redis-backed idempotency ensuring duplicate-safe execution. Implemented CQRS with PostgreSQL read models and exposed via GraphQL with structured logging and Prometheus-based observability.

Architected a cloud-native microservice backend using FastAPI with a decoupled gRPC-based analytics service to isolate traffic processing from user-facing APIs. Implemented JWT authentication with refresh token rotation, Redis-backed revocation, distributed rate limiting, and RBAC. Deployed PostgreSQL on Amazon RDS with Alembic migrations, containerized services via Docker, provisioned infrastructure using Terraform, and integrated Jenkins CI/CD pipelines.

Developed a real-time embedded monitoring system in C++ integrating piezoelectric sensors for structural fault detection. Built a low-level data acquisition pipeline with FFT-based spectral analysis and feature extraction under strict operating constraints. Architected a multithreaded on-device classification workflow achieving 96% accuracy with deterministic execution and controlled memory footprint.
