What I'm looking for

I’m looking to build backend and serverless, event-driven systems on AWS—owning production-readiness, migrations, and scalable APIs—while using AI-assisted tooling to improve dev/ops workflows and deliver measurable reliability and performance.

I’m a backend engineer with 10 years of experience building and evolving Node.js/TypeScript services on AWS at scale. At Nike, I owned privacy and consent APIs serving ~1.4B monthly requests, delivering 99.9999% availability with ~30ms average latency while driving architecture migrations that removed a ~1.2M-invocation/month dual-write pipeline—validated in one week with zero incidents.

I also built event-driven audit-log and data-lake delivery pipelines using DynamoDB Streams, SNS/SQS, S3, Kinesis, Lambda, and Glue (processing ~30.5M monthly messages with zero failure-queue events) and led production-readiness for consent and permissions updates across global marketplaces. I bring cross-functional delivery experience across product, legal, and mobile teams, mentored 2 engineers, and apply AI-assisted engineering with Cursor-based agentic workflows and LLM tool integration to automate dev and ops—plus hands-on exposure to Web Developer work delivering WordPress sites and API integrations.
