Software Engineer with 13 years of experience building distributed systems at scale.

Currently at Amazon, designing multi-region services and driving large-scale system migrations. Previously at IBM Labs, building CI/CD infrastructure for enterprise platforms.

• Distributed Systems — Multi-region services with sub-second latency, state-machine workflows, cross-partition data delivery
• Large-Scale Migrations — Migrated 8 major versions of a search engine (50+ components) while maintaining zero-downtime capability
• Infrastructure as Code — CDK/CloudFormation for multi-region ECS deployments, cross-account IAM, DNS delegation
• Developer Tooling — Release automation, operational dashboards, AI-powered oncall tooling

Languages:    Java · Python · TypeScript · Shell
Cloud:        AWS (ECS, DynamoDB, SQS, S3, Lambda, IAM, CDK, CloudWatch)
Systems:      Elasticsearch/OpenSearch · Multi-region architecture · State machines
Infra:        CDK · CI/CD pipelines · Containerization · Multi-arch builds (x86/ARM)

Merged fixes to widely-used projects:

• uutils/coreutils (Rust reimplementation of GNU coreutils):
  • #14574 — ln: fixed a data-loss bug where ln -f deleted the destination when the link failed
  • #14076 — cp: honor --reflink=never on macOS
  • #14075 — printf: plain-text help headings
• OpenSearch — DiskThresholdMonitor read-block auto-release (#22610)
• is-it-fixable — a CLI I built and published to npm that scores whether an open GitHub issue is worth working on (deterministic rubric, TypeScript)

Interested in: distributed-systems reliability, the OpenSearch/coreutils ecosystems, and developer tooling.

• System design for real-time computation at global scale
• Shadow testing frameworks for safe production migrations
• AI-powered developer experience tooling
