Cover image for I built and shipped end‑to‑end

I built and shipped end‑to‑end product features across web and mobile using React and React Native, supported by Scala backend services and APIs. I developed responsive, reusable UI components in React and implemented cross‑platform mobile screens in React Native with a focus on performance and usability. I designed and integrated Scala API endpoints and business logic to power client workflows, including validation, error handling, and data processing. I improved application performance by optimizing rendering, state management, and network requests across React and React Native clients. I collaborated with product, design, and QA to deliver production releases, write tests, review code, and troubleshoot issues in production.

At Mynd, I worked on building and scaling a property management platform focused on rental operations and investor services. I developed backend services using Python and Java to support leasing workflows, payments processing, owner reporting, and tenant management. On the frontend, I built responsive user interfaces using React, enabling property owners and residents to manage accounts, view financial data, and interact with the platform seamlessly.
