At Flexport, I build backend systems for the Warehouse Receiving and Inbound platform: Node.js/TypeScript services on AWS, React/Next.js on the frontend. I own design through production support. Highlights: • Led development of the Receiving and Putaway flow for Flexport's native WMS, replacing third-party tooling with an in-house event-driven pipeline • Designed ExecuteAsync, a generic async job execution framework (SQS + Lambda) that converts long-running synchronous API calls into queue-based jobs with idempotent retries and dead-letter handling, built to work around API Gateway's 30s timeout without the overhead of Step Functions • Built an AI-powered incident investigation assistant (LLM + RAG + MCP integrations) that automates first-pass triage against Datadog and internal systems • Designed a deterministic, idempotent event-based attribution flow that eliminated a recurring class of support tickets • Shipped merchant-provided ASN/PO receiving using composite database indexing, and an OCR-based receiving pipeline for barcode-less shipments • Delivered International DTC, integrating Flexport's core systems with omni-channel platforms Stack: Node.js, TypeScript, React, Next.js, Java, PostgreSQL, AWS (Lambda, SQS, RDS)

About

I'm a software engineer who designs and owns backend systems that carry real business risk in production. At Flexport, I build event-driven backend systems for the Warehouse Receiving and Inbound platform using Node.js, TypeScript, React, and AWS. Recent work includes leading the Receiving and Putaway flow for our native WMS, designing an async job execution framework (SQS + Lambda) to work around API Gateway timeouts, and building an AI-powered incident investigation assistant (LLM, RAG, MCP) that speeds up on-call triage. I've also shipped merchant-provided receiving, OCR-based label-less receiving, and an International DTC integration. I stay on-call for mission-critical logistics infrastructure. Before this, I worked at Amazon on the Product Detail Page, a Tier-1 surface serving hundreds of millions of users. I focused on performance, UX, and personalization, including Prime-specific filtering, latency reductions, and early LLM-driven personalization experiments. I care about clear system design, correctness, and long-term maintainability. I prefer roles with real ownership, where I'm responsible for decisions and outcomes, not just implementation.
