Control
Product Engineer
November 2024 - Today (1 year and 9 months)
Built Control's iOS app from 0 to 1 and scaled it into a full product used in production. Took full ownership of the mobile codebase from day one — architecture, CI/CD, App Store releases, and feature development.

Over time, expanded scope beyond mobile to contribute across backend and frontend, acting as a generalist engineer wherever the product needed it.

Also played a product engineer role, bridging product and engineering — translating business requirements into technical specs, coordinating across teams, and making sure what got built actually matched what users needed.

Stack: Swift, SwiftUI, Node.js, React, Fireblocks integration.

Bitstack
Mobile Lead
BANKING AND INSURANCE
May 2023 - October 2024 (1 year and 5 months)
París, France
Led mobile at Bitstack (YC S22), a Bitcoin savings app. Owned the full mobile roadmap — made the call to migrate from a legacy codebase to a new Flutter app from scratch, and drove that rewrite while keeping the existing app stable in production.

Took end-to-end ownership of architecture, Apple Pay and Google Pay integrations, real-time data via Firebase, and App Store releases. Worked closely with the CEO and product team to prioritize what got built and when.

Stack: Flutter, Dart, Firebase, CircleCI.

iOS Engineer
November 2021 - May 2023 (1 year and 6 months)
Austin, United States
Built the iOS app from scratch for Hoseki, a platform helping users verify and custody their Bitcoin. Owned the full mobile codebase while also contributing to the web platform and backend API integrations.

Worked across the stack — Swift on mobile, Node.js on the backend — in a small team where everyone wore multiple hats and shipped fast.

Stack: Swift, Node.js, blockchain exchange APIs.
