Projects

Here’s some stuff I’ve worked on in the past!

Crowdtest

AB test viral tweets with social simulation

Features:

  • Prediction tool to help creators know how their audience will respond to tweets before they post
  • Genetic algorithm refines tweets based off of the user’s tone, diction, and style in past tweets
  • OpenAI Agents SDK simulates hundreds of user reactions in parallel, reducing runtime to ~1 minute from 10 minutes

Social Stockfish

Real-time consequence reasoning engine for conversations

Features:

  • Tri-agent system to predict the best responses to the most likely replies and evaluate conversation in the context of a goal
  • Parallel processing enables the simulation hundreds of conversations through 6 layers of conversation depth using Llama 3.3 70B, in ~10 seconds
  • Monte Carlo simulation uses probability-weighted simulations to optimize responses
  • iMessage integration in a live chat editor, showing branching conversation trees with analysis in real-time
  • Best overall hack @ Columbia DevFest

SATA for Segmentation

Applying spatial autocorrelation token analysis to improve robustness of segmentation models

Features:

  • SATA [Nikzad et al.] improves vision transformer robustness on classification tasks by grouping tokens based on spatial autocorrelation
  • Compared five SATA variants, testing token-position restoration, cosine similarity versus attention scores, and exclusion of register tokens, finding an improvement on mIoU from 2.5% to 23.8%
  • Built custom ADE20K-C robustness benchmark of 15,000 corrupted images across 15 corruption types and 5 severity levels to evaluate segmentation degradation under distribution shift

Arrr-gumentor

Debate engine that knows exactly what your opponent is going to say before they say it

Features:

  • Turned the real-time consequence reasoning engine into the best debate prep tool
  • View debate trees in a interactive graph to study the best counters to hundreds of claims
  • Practice debating against the reasoning engine in a voice agent, and see how it would respond to your arguments
  • Runner up for best UI/UX @ the piratey HopperHacks X
