Led selection and implementation of front-end tech stack for a greenfield SMB billing/owner-management app.

• Built and maintained the React + Tailwind + TypeScript codebase, and shipped on schedule.
• Owned UX polish—created a shared component library and design system, implemented various missing UI flows, icons, edge-state, and error-handling, to deliver a production-grade experience.
• Used Zustand and Zod to address complex state management requirements, and to improve code quality and maintainability.
• Collaborated with backend and deployment pipelines to streamline releases.

Also maintained and improved a React + Material-UI + JavaScript web app from the sister business, which had been built for similar purposes.

Successfully transitioned to mobile app development; using React Native and Expo, contributed significantly to re-launch of iOS/Android app for clients’ customers.

Played a key role in modernizing the UI and improving performance:

• Designed and launched The 11:23AM Daily Deal Drop — this new feature achieved user engagement rates over 50%.
• Updated the mobile app from Expo Go to Expo development builds.
• Replaced traditional email/password sign-in with a mobile-first SMS OTP authentication flow using AWS Cognito.

Responsible for design of software applications, internal and external web sites, and web applications.

• Improved the previously-engineer-designed interface of main web application, resulting in a good-looking UI loved by managers, customers, and even engineers.
• Built and maintained main external site.
• Built and maintained employees-only intranet. With a high design concept, this Adobe AIR site was finicky, but lovely.
• Coached new employees in using company’s software.

Responsible for workload and personal growth of programmers.

• Managed group of 5 programmers.
• Hired 1 full-time and 6 freelance programmers.
• Worked across disciplines: Coordinated with 6 project managers, 4 design directors, technologists at other offices and many client representatives.

Partial client list: Schlumberger, Newsweek, HBO Screening Room, AOL @ School, Goldman Sachs intranet, NetMarket, IBM intranet, Datek, Univision, Gateway.

Responsible for design of power supply for a new color copier product, prototype electronics, design of copy-controlling functionality and mechanical interface for sensors and heater.

• Created performance and regulatory specification and defined technical criteria to evaluate vendor qualifications, resulting in selection and implementation of a power supply used world-wide.
• Redesigned analog circuit and edited reference specification for clarity, achieving proper execution of copy-controlling function on a color copier with no field failures and no customer complaints.
• Redesigned paper sensor circuit, thus ensuring a smooth production ramp with no shutdowns for this sensor.

Responsible for main electronics boards for three printer and copier products, seeing to design quality, cost and reliability improvements, warranty performance and support issues; also responsible for production-line issues.

• Improved functional test of electronics board at contract manufacturer through improvements to test software, eliminating 2 failure modes of the board at top-level factory.
• Reprogrammed DOS end-of-line testing for copier product, which resulted in an assembly-time reduction of 2 minutes per unit.
• Reduced high servo subsystem failure rate by over 90%.

Open-source React project from Hack For LA

• Brought cohesion to team’s use of Material-UI
• Wrote Cypress tests, expanding code coverage from 50% to 91%
• Wrote and edited documentation
• Within a month, became main contributor

React + GraphQL SPA, large side project

• Built with Vulcan, which uses Meteor
• Wrote 71 React components
• Used Redux, Apollo, Twilio, and many npm libraries
