What I'm looking for

I'm looking to build web or iOS products where I can work on frontend or full-stack development, collaborate closely with UX and accessibility teams, and ship reliable user-facing features.

I led frontend development for WellsTrade’s retirement investment platform at Wells Fargo via Sibatel Communications, replacing legacy jQuery with React, Redux, and Redux-Saga across three retirement products.

I managed more than two developers within an Agile Scrum team, partnered with UX and Accessibility teams on WCAG 2.1 AA compliance, and collaborated with Java Spring teams to define REST API contracts. I also delegated sprint work and delivered biweekly demos to product and project stakeholders.

At eBay, I built a React analytics dashboard for high-volume sellers to visualize sales transactions, loans, and earnings. Earlier at Intekglobal, I designed a full-stack real-time messaging application with React, Node.js, Express, MongoDB, JWT authentication, Socket.IO notifications, and Dockerized microservices.

I’m currently building Sudoku: Daily & Offline, a SwiftUI iOS app with SwiftData, iCloud sync, OpenCV and CoreML grid recognition, localization, subscriptions, daily challenges, and an in-app coin economy.
