I’m a Backend Software Engineer with 6+ years of experience building high-scale, mission-critical APIs and cloud-native microservices in production. I focus on pragmatic design that supports real-world performance, security, and long-term maintainability.

I’ve owned services end-to-end—from technical design through deployment, observability, and incident response. In production, I built RESTful APIs using FastAPI and Async IO handling 100K+ concurrent requests with consistently low latency, and I implemented OAuth 2.0 and JWT-based authentication to protect sensitive data.

My work often improves reliability and speed: I migrated legacy Java Spring services to Python FastAPI microservices, improving API response times by 40% and simplifying maintainability. I also optimized PostgreSQL using partitioning, indexing, and SQLAlchemy ORM—boosting database throughput by 60%—and reduced deployment time by 75% with CI/CD pipelines.

I’m equally comfortable with event-driven systems and data pipelines. On AWS, I designed and deployed event-driven architectures using Lambda, S3, SNS, SQS, RDS, and DynamoDB, and scaled ETL pipelines with PySpark, cutting processing time by 40%. I bring strong testing discipline (Pytest, SQLAlchemy) and proactive observability (CloudWatch, Splunk, Dynatrace) to reduce incident resolution time by 35%.
