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.

01

Retail B2B Platform Suite

2025 — Present

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.

Care CRM

CRM surface built as part of the broader platform evolution, with focus on reusable foundations, consistent operator flows, and room to scale.

Commerce App

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.

Seller CRM

2024 — 2025

Built and maintained a seller-facing CRM handling 100+ orders/day and over $1M/month in operations. Improved the system from both sides: product behavior for operators and backend foundations that cut infrastructure costs by 30% and made complex pricing logic possible.

B2B Management Suite

2021 — 2023

Built an app that consolidated 60+ management tools into one experience for 200+ B2B clients. Used no-code MVPs to validate new workflows before moving the best ones into the product roadmap, and supported adoption by training consultants on the rollout.
