About me

Building at the edge of AI & infrastructure

I'm a Software Engineer at Amazon Web Services, where I've spent 4+ years owning distributed backend systems at global scale — across the Athena query engine and Aurora MySQL teams.

My recent work sits at the intersection of backend infrastructure and AI: I architected a production RAG system using Amazon Bedrock and OpenSearch, and built LLM-powered pipelines that cut investigation time from 2 hours to 5 minutes.

I thrive in environments where ownership is real — I've led cross-functional migrations, shipped compliance region deployments, and debugged production JVM memory leaks impacting 10K+ queries across 3 regions.

If you're building something interesting in backend or AI infrastructure, I'm always happy to connect and swap ideas.

Where I've worked

Software Development Engineer
Feb 2024 – Present
Amazon Web Services — Athena
  • AI-Powered RAG Assistant: Architected an enterprise AI assistant using AWS Q Business with a RAG architecture, integrating Amazon Bedrock and OpenSearch vector databases — delivering responses from 100+ internal sources at sub-15s latency.
  • LLM Orchestration Pipeline: Built an automated ticket validation system using Lambda, SQS, and LLM prompt orchestration — reducing investigation time from ~2 hours to ~5 minutes.
  • JVM Memory Leak RCA: Led multi-day root cause analysis for a production memory leak (classloader leak in Trino aggregation path) impacting 10K+ queries across 3 regions; validated a 4-line fix through pre-production testing.
  • Compliance Region Launch: Led first-ever deployment of Athena query infrastructure into 3 air-gapped government compliance regions, coordinating across 8+ teams.
  • API Security Migration (88K accounts): Owned end-to-end deprecation of 18 legacy APIs across 29 AWS regions — 95% migration rate, zero customer impact.
  • Large-Scale Data Platform: Built a 600+ GB cross-account data pipeline using DynamoDB PITR exports to S3 and Athena for intelligent query routing across 3 regions.
Software Development Engineer
Sep 2021 – Feb 2024
Amazon Web Services — Aurora MySQL
  • Scalable Test Framework: Designed and owned a backend test framework for Aurora MySQL (5.7 & 8.0), validating engine releases across multiple AWS regions at global scale.
  • Infrastructure Optimization (25%): Reduced infra utilization by 25% via dynamic resource scaling; decreased testing turnaround by ~10% through intelligent capacity management.
  • Internal API Design: Designed REST APIs for automated RDS cluster provisioning using AWS Fargate and DynamoDB.
  • CI/CD & Observability: Built CI/CD pipelines and CloudWatch dashboards across all test environments; led cross-region MySQL RDS cluster migration.
Software Developer
Mar 2021 – Jul 2021
Value Exchange
  • Built Django/Python backend services on AWS; designed MySQL data models supporting 20K+ records with automated CI/CD and S3 storage.
