II Experience bearings taken
01 research assistant · gisense lab mar 2026 —
gisense lab · austin, tx · fix nº 01
  • Reproduced and fine-tuned baseline models to generate landscapes from sound.
  • Developing and evaluated raw video datasets.
  • Currently engineering multimodal EEG models for human-centered applications.
02 backend/ml engineer · tx luminescence sep 2025 —
tx luminescence · austin, tx · fix nº 02
  • Developed back-end architecture for an AI-powered educational app for K–12 learning.
  • Integrated AI model with RAG to enhance app functionality and learning outcomes.
  • Flask, Supabase.
III Projects soundings, in order taken
01 ecoscan mar 2026
python · yolov11 · sounding nº 01
  • On-device waste detection app with FastAPI backend.
  • Fine-tuned YOLOv11 for waste classification — 24 recyclable and hazardous waste classes.
  • Placed top 30 out of 500+ teams at Woz Hackathon.
02 contextosolver apr 2026
word2vec · glove · fasttext · svd · sounding nº 02
  • Compared Word2Vec, GloVe, FastText, and SVD under the same training setup to test whether algorithm choice alone changes embedding geometry.
  • GloVe and SVD are strongest for Contexto-style navigation; Word2Vec performs best on word-similarity benchmarks.
  • Reproducible and controlled study; conclusions limited to one English corpus, fixed dimensions, and a capped vocabulary.
03 takemeter jun 2026
python · distilbert · huggingface · groq · sounding nº 03
  • Fine-tuned distilbert-base-uncased on 202 hand-labeled UT Austin Discord posts across four discourse categories.
  • Found a zero-shot llama-3.3-70b baseline beat it 90.3% vs 71.0% — diagnosed the gap as a topical-keyword shortcut that collapses on function-defined labels.
  • Validated with Cohen's κ=0.869 inter-annotator agreement and confidence calibration (100% accuracy above 0.5 softmax).
04 mypersona mar 2026
python · asyncio · discord.py · sounding nº 04
  • Real-time Discord bot generating persona-based replies.
  • Few-shot prompting engineered from real user message corpora.
  • Groq and Kagi APIs — 250+ languages and styles supported.
05 utfoods jun 2026
python · sentence-transformers · groq · gradio · sounding nº 05
  • RAG QA over 60 review-level chunks scraped from Reddit, Yelp, Discord, and local news on UT Austin dining.
  • MiniLM embeddings with cosine retrieval, grounded llama-3.3-70b generation at temp 0.2 with out-of-scope refusal.
  • Inline source-file citations suppressed on refusals, served through a Gradio query interface.
