Built and shipped 3 production Web3 applications with a frontend focus, using React, Next.js, and TypeScript to deliver scalable, user-centric interfaces. Designed and maintained end-to-end testing workflows reaching ~85% test coverage, catching bugs earlier in the cycle and reducing manual QA time before handoff to the QA team. Collaborated on blockchain, smart contract, and DevOps tasks through pair programming and technical discussions, broadening delivery across the stack. Integrated AI-assisted development tools (Claude Code, GitHub Copilot) into daily workflow for research, debugging, and code generation, improving development efficiency and turnaround. Participated in client meetings, project planning, and status reporting within a fully remote, asynchronous international environment.

Developed a white-label web platform for purchasing and managing bonds, stocks, and CEDEARs, owning frontend delivery and contributing across the stack. Built and configured an internal Material UI component library (~8 foundational and ~20 high-level components) plus its Storybook integration, adopted by 2 teams and ~7 developers to improve UI consistency and developer efficiency. Collaborated with the UX/UI team to align design decisions with technical constraints, applying SOLID principles for maintainable code.

Led the migration of a legacy Odoo web system to a cross-platform Flutter mobile app, fully restructuring the frontend UI/UX and re-wiring backend logic in Python and Dart for responsive functionality across Android and iOS. Developed custom modules for the ERP health-insurance system on the Odoo framework, applying an MVC architecture and optimizing performance for high-data-volume operations serving a client with 48,000+ members.
