Experience
ATP Fitness
http://www.atpfitness.appAs the owner of ATP Fitness, I was responsible for all aspects of the application, bringing the project from conception to launch on both the iOS and Android platforms. It is built with an offline-first approach, leveraging SQLite to allow users to run the entire app without a network connection. Custom native modules were developed using Swift and Kotlin. The design is entirely custom and implemented using themes that can be altered by the user. The application allows users to target certain muscle groups and select the equipment they have access to, and the application will generate a workout based on their selections.
Puttshack
https://www.puttshack.com/At Puttshack, in my capacity as a full-stack developer with a primary focus on back-end technologies, I was integral in architecting and implementing a back-end system using NestJS. My role involved extensive work on building APIs that were performant and integrated with several other back-end systems and microservices. This included connecting with Puttshack's internal booking systems and handling interactions with third-party APIs for loyalty programs, marketing tools, and point of sale (POS) systems. One of my notable contributions was the development of an API that managed and streamlined payment processes, significantly enhancing the booking experience for customers.
Lungo (Acuity Scheduling; via Toptal)
https://www.acuityscheduling.comDuring my tenure as a full-stack engineer on the Lungo project, a sophisticated scheduling platform, I played a pivotal role in developing and managing the back-end infrastructure. My responsibilities included developing a scalable GraphQL server, which served as the singular entry point for the platform's single-page application. This involved not only the creation but also the optimization and management of the server, ensuring seamless handling of a wide range of GraphQL queries, mutations, and subscriptions. To improve the integrity and efficiency of the GraphQL server, I developed a custom test suite as well as an integration with Apollo Engine. This integration was crucial for monitoring key metrics and performance, ensuring the back end operated at optimal levels.
Ingage Corporate Health and Wellness

Walmart Mobile Developer
I built a React Native SDK with native iOS and Android modules to power an AI Vision camera system deployed across Walmart store locations, enabling associates to perform real-time inventory and pricing verification through custom computer vision models. I bridged complex native camera functionality into JavaScript APIs while maintaining thread safety and memory efficiency across both platforms to support high-throughput scanning sessions. I partnered with product and data engineering teams to align technical capabilities with store operations requirements, iterating on feedback from floor associates to refine the user experience. I also established comprehensive performance benchmarks with QA, profiling native modules to eliminate frame drops and optimize memory usage during continuous camera operation.
McGraw-Hill: Full-stack Developer
https://studysharpen.com/I developed a Next.js administrative portal with real-time content management capabilities backed by GraphQL subscriptions, enabling educators to dynamically update curriculum materials and learning paths without deployment cycles. I engineered a complementary native iOS application focused on personalized learning optimization, implementing adaptive algorithms that adjusted content difficulty based on student performance metrics and engagement patterns. I architected a video streaming infrastructure with adaptive bitrate handling and offline caching capabilities to support multimedia learning resources across variable network conditions. I also synchronized user profiles, progress data, and assessment results across web and mobile platforms to ensure continuous, seamless learning experiences regardless of device switching.
Wellth
https://www.wellthapp.comAs a mobile engineer on the Wellth React Native application, I led the multi-factor authentication (MFA) initiative, designing and implementing the full authentication flow across iOS and Android. I integrated Statsig feature gating to enable controlled feature rollouts and A/B experimentation, and spearheaded the migration from React Native 0.74 to 0.83, resolving breaking changes and improving build stability. Day-to-day responsibilities included building new features, improving app stability, and enhancing the overall user experience for Wellth's health and wellness platform.
Anthem BCBS Principle Engineer
I led full-stack development on a HIPAA-compliant telehealth platform supporting secure, real-time patient and provider video interactions, owning both front-end architecture and back-end integration layers across engagement. I also built and owned a front-end UI system approved for user-facing products, working with the digital platform team to establish standards adopted across teams, and integrated Qualtrics APIs to capture user experience data with feedback routing based on user personas.
