Senior full-stack engineer. I build products end to end: the interface, the services behind it, and the infrastructure underneath. Backend and distributed systems are where my depth is. Payments ledgers, event-driven architecture, Kubernetes platforms. Frontend isn't a side skill. I've rebuilt a storefront from jQuery to React, shipped a merchant dashboard used daily by 12,000 businesses, and rewritten a booking interface in Vue 3 for users on cheap Android phones over bad connections. Owning a feature from database to browser beats negotiating an API boundary with another team. More recently I've moved into AI/ML engineering. That has meant building LLM-powered features end to end (retrieval pipelines over pgvector, agent workflows, streaming interfaces) as well as the infrastructure underneath them: model serving with vLLM, GPU scheduling on Kubernetes, and evaluation harnesses that catch the failures automated tests score as passing. Before the LLM era I built and shipped a fraud scoring model in production, so the ML side isn't new. Only the scale of the models is.
