What I'm looking for

I'm looking for remote product engineering work where I can own meaningful problems across backend systems, integrations, AI workflows, and production reliability, while partnering closely with product and customers.

I build product-critical backend systems at Husk, from card issuing and expense management to accounting integrations, pricing decisions, and customer-facing metric integrity. I take product problems from domain research and vendor API validation through scope, implementation, and production ownership.

Across a multi-tenant AI SaaS product, Monite, and large-scale data-collection platforms, I've delivered AI pipelines, integrations, reliable APIs, and 250+ collection pipelines while leading engineers and working directly with customers. I use AI tools throughout engineering work while keeping product judgment, architecture, and production accountability with the engineer.
