About

I’m a second-year CS major translating raw race-car bytes into winning insights for UT Austin’s Formula SAE EV Team — and building the real-time systems that keep competition software reliable under pressure. At Longhorn Racing, I work on a distributed telemetry stack spanning on-car data ingest, real-time streaming, persistent storage, and live visualization, turning high-frequency vehicle data into actionable insight for engineers and drivers in the moment.

That same systems-first mindset carries beyond the car. I co-founded and lead the technical direction of Longhorn Sim Racing, where I’ve designed and shipped a production-grade web platform built with Next.js, React, and TypeScript. The platform supports member accounts, event registration, admin tooling, statistics dashboards, and the foundation for digital payments and notifications — all built for scale, reliability, and real organizational use.

Across both domains, I optimize for tight feedback loops, clear abstractions, and durable software that ships fast and performs under pressure. Iterate • Improve • Deploy. Open to Summer 2026 SWE internships — let’s connect.

  • Co-founded Longhorn Sim Racing and serve as Chief Technology Officer, owning the design, implementation, and evolution of the organization's core digital platform.
  • Architected and implemented a full-stack TypeScript application (Next.js / React) supporting member accounts, event registration, admin tooling, and statistics dashboards.
  • Built internal admin tools to manage events, registrations, and member data, prioritizing reliability, clarity, and low operational overhead for non-technical officers.
  • Implemented production-grade SEO and platform discoverability, including structured metadata, sitemaps, breadcrumbing, and Google Search Console integration.
  • Integrated third-party commerce infrastructure into the core platform, building a custom storefront UI while leveraging Shopify for checkout, payments, and fulfillment workflows.
  • Established the technical foundation for future digital payments and notification systems, enabling scalable growth without re-architecting core infrastructure.
  • Owned the platform end-to-end, from system design and implementation to deployment, iteration, and ongoing maintenance.

2024 — Present
1 yr 6 mos
  • Develop and maintain a distributed, real-time telemetry system for a Formula SAE EV race car, supporting live data ingest, streaming, storage, and visualization during testing and competition.
  • Designed the on-car telemetry dashboard, balancing real-time data density, clarity, and reliability for use in high-speed, safety-critical conditions.
  • Work across the full telemetry pipeline, from on-car data ingestion through real-time distribution and persistent storage, enabling engineers and drivers to make time-critical decisions trackside.
  • Build web-based visualization tools in TypeScript / React for live timing, deltas, vehicle state, driver inputs, and energy usage, used across mobile devices, laptops, and trackside systems.
  • Integrate real-time streaming with backend data stores and processing pipelines to support analytics such as energy prediction and performance modeling.
  • Contribute to a safety- and reliability-critical codebase where correctness, latency, and fault tolerance directly impact on-track decision-making.
