- Jeffrey G. Wang

dcHiC: Co-writer and maintainer this open-source scientific computing package. Wrote routines for memory-efficient low-rank PCA, genome wide hypothesis testing, and large-scale visualization.
Quidio: Co-founded marketplace for technical knowledge and bounties—basically replit bounties but one year earlier. Led eng/product; scaled to hundreds of users.
Teambooth: Federated fine-tuning of Dreambooth diffusion models. Built as a fault-tolerant distributed system with Raft and gRPC that runs 18x more cost effectively than a centralized server.
Stochastic team selection: Optimal team assignment is an NP-complete combinatorial optimization problem. This simulated annealing algorithm does well and is used by several Harvard clubs.
Misc: I helped develop and currently maintain classes.wtf, a course search tool built on Redis/Go/Svelte that is 100x faster than MyHarvard. I’ve also enjoyed speaking art to life, visualizing my social network with Obsidian, and speeding up LLMs with speculative sampling.

Co-led the largest student-run venture competition at Harvard, with over 75 entrants, $100k in prizes, and sponsors ranging from AWS University to Z Fellows.
Conducted policy research on telecommunications in the US and China @ the HKS Mossavar-Rahmani Center for Business and Government
