Emma Choudhary

About

Backend/data engineer with hands-on production experience building partner-facing Python APIs (FastAPI, Celery, Postgres/Redis) and AWS serverless data platforms (Lambda, SQS, Step Functions, Glue). Emphasizes reliability and governance—JWT tenant-scoped auth, secrets/config hygiene, data-quality quarantine, and incident ownership—plus measurable SQL tuning that eliminated timeouts and stabilized reporting workloads.

Experience

Key Strengths

• Designed stateless FastAPI services behind an API gateway with PostgreSQL/Redis and Celery async processing for bursty partner traffic
• Implemented JWT-based auth with tenant scoping via claims, key rotation, and auditing for sensitive endpoints
• Built AWS serverless/event-driven workflows (API Gateway + Lambda + SQS + Step Functions + EventBridge) with Terraform and GitHub Actions CI/CD
• Strong secrets/config management across environments using SSM Parameter Store, Secrets Manager, and least-privilege IAM
• AWS Glue ETL design with partitioned S3 Parquet lake, Glue Catalog, Athena/Redshift Spectrum, schema enforcement, and data-quality quarantine patterns
• Production SQL performance tuning (indexes, partitioning, keyset pagination) reducing timeouts to near-zero and improving endpoint latency to ~300–900ms
• Owned data pipeline incident response: detected via CloudWatch/freshness checks, triaged schema change, paused publishing, hot-fixed mapping, backfilled, and added completeness/schema contract gates
