Key Strengths
Designed and maintained production Python backend services with Flask, PostgreSQL/SQLAlchemy, Redis caching, and Celery background jobs
Implemented API reliability patterns: JWT + RBAC auth, explicit HTTP timeouts, retries with exponential backoff, and circuit breakers
Delivered serverless AWS architectures (Lambda + API Gateway + DynamoDB/S3/SNS) with CloudFormation IaC and GitHub Actions CI/CD
Built AWS Glue ETL pipelines (S3/RDS sources) using PySpark, DynamicFrames for schema evolution, and data quality validation with CloudWatch/SNS alerting
Modernized a monolithic CRM into domain-based REST services with parity validation via parallel runs, stakeholder demos/UAT, and feature toggles
Improved a large-scale SQL reporting query from ~10 minutes to ~30 seconds (~95% reduction) using indexing, date partitioning, join changes, and window functions
Owned and remediated a batch/data pipeline incident by diagnosing API timeouts via CloudWatch metrics/logs, mitigating via manual retries/timeouts, and preventing recurrence with better monitoring and retry/circuit-breaker controls
