Design, building, and deployment of backend systems engineered for high concurrency, low latency, and reliability. Whether migrating existing services, scaling database layers, or building automated cloud deployment pipelines, I focus on system correctness, strict data invariants, and efficient resource utilization.

Asynchronous APIs: High-throughput REST services built with FastAPI, Pydantic v2, and async ORMs.

Cloud Infrastructure: Multi-environment deployments on AWS (EC2, RDS, S3, ECS) and Microsoft Azure using Docker and Terraform.

Database & Storage Engineering: PostgreSQL connection pool optimization, indexing, Alembic migrations, and distributed caching with Redis.

Security & Hardening: Rate limiting, IP filtering, API gateway configuration, encrypted data transit, and security audits.
