002About

I like building products where the architecture, the user experience, and the business outcome all matter at the same time.

Five years shipping across e-commerce, logistics, and B2B. My work spans Flutter, TypeScript, and Node.js, but the common thread is ownership — I care about the whole system: the architecture, the user experience, the rollout, and the metrics after it ships.

I'm drawn to product surfaces that cut across platforms, where mobile, web, backend, and operational reality all have to line up for the experience to work.

Product work across multiple surfaces inside the same company, spanning campaign tooling, commerce experiences, and newer care flows — with shared responsibility for the systems that made them reliable to ship and evolve.

SmartCare

Newer product surface in the suite, shaped as part of the broader platform evolution with the same concern for reusable foundations, consistent flows, and room to scale.

Abastece Shop

Commerce-facing app work tied to the wider retail operation, with focus on dependable customer flows and product structure that could keep pace with business growth.
