Frameworks: PyTorch, TensorFlow, scikit-learn, LightGBM

Software & Systems: Python, C++, TypeScript, JavaScript, Node.js, React/Vite, REST APIs, OAuth 2.0, GCP/Firebase, Cloud Functions, Firestore, Cloud Storage, testing, CI/CD

Selected Technical Projects

Mendmark | Mutation Testing for Agent Evals

GitHub · PyPI · 2026

  • Built an open-source Python tool that plants controlled failures in passing agent traces, reruns a team’s DeepEval metrics, and fails CI when those evals miss wrong tool arguments, repeated side effects, hidden tool errors, or damaged responses.
  • Published a versioned golden set with 24 cases, 13 tool contracts, and 263 pinned mutations across ten domains. A response-only evaluator missed 176 faults while a complete trace-and-outcome evaluator caught all 263.

lgbm-to-code — Cross-Runtime ML Inference

GitHub · PyPI

  • Built a code generator that turns trained, one-output LightGBM models into dependency-free Python, C++17, or JavaScript raw-score inference.
  • Added executed and compiled parity tests across all three runtimes at 1e-12 tolerances, including missing-value routing and explicit rejection of unsupported model types.

Professional Experience

SyncABill — Founder & Applied AI Engineer

2025–Present

  • Built and deployed a React/Vite invoice application with TypeScript and Node.js services on Google Cloud/Firebase, using Firestore for workflow state and Cloud Storage for source documents.
  • Connected structured document extraction to deterministic checks, controller-configured review rules, and QuickBooks Online or Xero.
  • Completed Google’s CASA Tier 2 security assessment and brought the product to SOC 2 readiness.

Casabauhaus — Founder & Operator

2022–Present

  • Operate a vintage-furniture business spanning sourcing, pricing, merchandising, sales, and delivery, supported by agent and API workflows for reporting, social media, seasonality analysis, and Shopify.
  • Developed furniture-valuation and mid-century classification models used in sourcing decisions, including a fine-tuned CLIP model built before modern vision-language models were widely practical.

Perfsy — Founder & Machine Learning Engineer

2021–2022

  • Built a computer-vision pipeline to extract structured fields from scanned DMV vehicle titles.
  • Normalized scan orientation with OpenCV and experimented with character primitives, autoencoders, convolutional features, and DNN classifiers.
  • Created data and evaluation workflows to inspect recognition failures and improve the pipeline.
