Delivered an internal AWS TV video-processing platform using Step Functions/Lambda/S3/DynamoDB with strong reliability and cost controls, and built Glue-based ETL for compliance/risk events (Kafka to partitioned Parquet). Also modernized legacy compliance systems into Java/Node event-driven services and has demonstrated measurable SQL tuning impact (200s to 20s).

Key Strengths

  • Designed and operated a production serverless video-processing pipeline on AWS (S3, Step Functions, Lambda, DynamoDB)
  • Reliability engineering: idempotency, retries/backoff, timeouts, clear error categorization, and CloudWatch monitoring/alarms
  • Cost and scaling control in serverless workflows (concurrency limits, batching, tuning memory/timeouts, retry policy optimization)
  • Built ETL pipelines with AWS Glue from Kafka/API logs to partitioned Parquet on S3 with schema evolution and data quality handling
  • Modernized legacy compliance/risk batch logic into owned event-driven services with parallel-run parity validation and gradual rollout
  • SQL performance optimization with execution-plan-driven indexing and materialized views; reduced query runtime ~90% (200s to ~20s)
  • Owned production incident response for batch/data pipelines; mitigated SLA misses via partition re-runs and improved lag-based alerting

“ML/AI engineer with hands-on ownership of production systems spanning classical ML fraud detection and GenAI agent workflows. At Fidelity, they built an end-to-end fraud platform that improved review queue Precision@K by 15-20% while reducing false positives 10-15%, and they also shipped RAG-based agent systems that cut manual workflow effort by 30-40%.”

“LLM/agent engineer who has shipped multiple autonomous, multi-step agents to production (document-to-SOP conversion, test generation, code generation) using a custom Python DAG orchestrator with persistent state, tool-calling permissions, and structured outputs (Pydantic/JSON Schema). Demonstrates strong production hardening practices—semantic contracts, golden-dataset prompt regression tests, circuit breakers, and multi-level monitoring—and delivered large productivity wins (34 hours of manual writing reduced to ~20 minutes review; ~15–20 engineering hours/week saved).”
