I study Computer Science and Statistics at UNC Chapel Hill and build software across distributed systems, data engineering and mobile. I lead software for a NASA-funded rover project, interned at IBM on an enterprise data migration, and build iOS and full-stack applications.
Experience
7 roles- Migrated 2M+ employee records from 14 legacy tables into an Oracle HCM schema using SQL and Python ETL scripts.
- Built a validation tool that caught ~3,000 data errors before migration, reducing failed load attempts from 5 to 1.
- Delivered a semantic-retrieval onboarding assistant that cut estimated time-to-productivity by ~30%.
- Building an EEG emotion-recognition platform.
- Consolidated three cross-validation strategies behind a single dispatch API, replacing ~150 lines of duplicated per-experiment code.
- Automated model tuning with an Optuna-compatible objective that sweeps 50+ configurations per run, reducing tuning time from ~11 hours to ~1 hour.
- Designing an H-class (160–320 N·s) solid-fuel rocket motor, sizing thrust, chamber pressure and mass flow from first principles.
- Rewrote the ballistics solver's inner loop in C++ with a pybind11 binding, reducing per-run time from 6.2 s to 85 ms and a 4,000-configuration sweep from ~7 hours to under 6 minutes.
- Lead the software team building an autonomy stack for four UGV Beast rovers.
- Built decentralized task allocation with a consensus-based auction algorithm (CBBA); the fleet converges in 10 ms without a central controller.
- Implemented a peer-to-peer gossip protocol that sustains 98% message reliability as rovers drop offline.
- Build and maintain the HackNC website, reducing load times by 40% for 500+ participants.
- Built ProjectLink with Node.js, TypeScript and Firebase Firestore, sustaining sub-second read/write latency across 50+ users.
- Built a route optimization model in Python, SQL and NetworkX, improving USPS delivery efficiency by 18% across 10K+ records.
Projects
6 selected- Orchestration engine coordinating four async LLM agents across a Research, Analysis, Decision and Execution pipeline, with each agent routed to a model tier by task.
- Executes live orders through a remote MCP broker over HTTP with OAuth, using client-generated UUIDs for idempotent submission and post-fill reconciliation.
- iOS app built for the 2026 AppTeam Apprenticeship Showcase, using MVVM with Swift's @Observable macro across 5 view models and 4 tab screens.
- Loads astronomy photos from 1, 5 and 10 years ago in a single render cycle using structured concurrency and withTaskGroup.
- Rebuild of TarHeel Eats. A nightly cron-triggered scraper parses UNC dining menus into Postgres, caching nutrition by date-stable recipe IDs.
- Warm runs fetch 0 of ~800 recipes and finish in 14 s instead of 553 s. Currently packaging for iOS with Capacitor and Apple Health write-back.
- Real-time browser game running a 60 FPS loop within a 16 ms frame budget for spawning, animation and collision detection.
- Combo-multiplier scoring engine with persistent high scores.
- Designed interactive tools (OrbitNotes, RoguePlanets, ExoplanetsVisualizer) to analyze exoplanet habitability across 36,000+ planets with a custom scoring algorithm.
- Platform for high school students to start, join and support real-world projects, with a Firestore backend supporting real-time collaboration for 50+ users.
