Hi there 👋 I'm David Jiang, check out my website!
I’m a Software Engineer at Uncountable, a YC-backed startup that builds a unified data platform for R&D organizations, chemists, materials scientists, formulation teams, and process engineers.
I recently graduated (May 2025) from the University of Wisconsin–Madison with a degree in Math and Computer Science, after spending several years pursuing chemistry and biochemistry. Some of my favorite courses were Arithmetic Algorithms, Programming Languages, Synthetic Organic Chemistry, Protein Motifs, Fractal Geometry, and Integer Partitions.
🧪 SciBowl.org — A full Science Bowl training & competition platform
A modern, web-based ecosystem designed for students, coaches, and tournament organizers.
I'm building SciBowl.org to address long-standing gaps in the Science Bowl community:
-
Massive Question Database
PDF → parsed → normalized → searchable, with category tags and difficulty metadata. -
Team & Individual Practice Modes
Short answer, multiple choice, and multi-select with clean UI and immediate feedback. -
Real-Time Buzzing System
Concurrency-safe scrimmaging. -
Player Analytics & Insights
Accuracy by category, speed distributions, long-term improvement tracking. -
Coach Tools
Rosters, custom practice sets, usage analytics.
(Fully bootstrapped. Hoping to turn this into a long-term edtech platform.)
- Advanced TypeScript + React patterns for scalable frontends
- Django & PostgreSQL optimization
- Methods in sports simulations
- Sonder — (Deprecated) ML-based dating-profile generator for songs using clustering + Spotify audio features
- DayTour — Travel itinerary builder using Google Maps API + traveling salesman heuristics
- Stavid — A Discord bot for apartment life: ledgering, restaurant recommendations, reminders, utilities
- Django, FastAPI, Python tricks, React
- Chess, poker, Rubik’s cubes, buzzing games, competition math, sports analytics, GeoGuessr
