Experiences

Sonorus Labs

September 2025 - Present

Founder/Independent Developer

Madison, WI

  • Developing an AI-powered SaaS creative tool for musicians that transforms natural-language prompts into theory-validated chord progressions and playable MIDI output.
  • Architected a production-ready system using FastAPI, Next.js, and a modular Python engine for intent parsing, deterministic music generation, and MIDI rendering.
  • Implemented music-theory–driven generation, MIDI export, browser playback, and Supabase backed persistence to support user history and usage analytics.

73 Strings

June 2024 - August 2024

AI/ML Engineering Intern

New York, New York, United States

  • Built and deployed LLM-based financial document parsers end-to-end, reducing processing time by 30% and improving extraction accuracy for private-equity analytics.
  • Developed, trained, and productionized a chart detection and classification model, improving precision to 93% (+12%) and recall to 94.4% (+11%). Achieved 92.2% mAP, and performed hyper-parameter tuning to reduce false positives and improve model reliability in production.

United Nations (OICT)

May 2024 - June 2024

AI/ML and Full Stack Intern

Remote

  • Built and deployed a Retrieval-Augmented Generation (RAG) system for a UN research portal, enabling context-aware querying over large collections of unstructured documents.
  • Designed and implemented document ingestion, preprocessing, and embedding pipelines, supporting scalable retrieval and low-latency inference in production.
  • Implemented research repository file-handling and storage workflows to support AI-driven document processing, contributing beyond core ML responsibilities and learning production systems on the job.
