Founding AI Engineer May 2026 — Present
Hyperspell · San Francisco
- I lead work on retrieval and answer synthesis, fusing frontier LLMs with traditional ML to find the right information quickly, get it into the model’s context window, and produce grounded, relevant responses.
Head of AI Apr 2025 — May 2026
HackerPulse · San Francisco
- Designed and built the AI service that powers the product — engineering leaders chat with an AI agent connected to live data from GitHub, Jira, Slack, Notion, etc. to get answers about their engineering org
- Built a self-reinforcing knowledge graph across all synced integrations — agents discover implicit relationships, each new connection helps surface the next, and the user-facing agent queries it via tool calls
Founding AI Engineer Apr 2023 — Dec 2024
Yuma AI (YC W23) · San Francisco
- Fine-tuned Mistral 7B to replace GPT-4 for ticket classification, cutting per-call inference costs by ~100x. Created an LLM-as-judge evaluation system to safely validate prompt changes and migrate between models
- Designed an active learning loop for ticket routing: embed tickets → SVM classifies known types → anomaly detector catches out-of-distribution tickets → LLM labels the unknowns → retrain
- Implemented the retrieval pipeline combining embedding search with BM25-style keyword matching
Machine Learning Engineer Apr 2019 — Mar 2023
Triplebyte · San Francisco
- Joined as the first ML hire; promoted to Tech Lead of Data & Infrastructure
- Migrated candidate search from a Postgres read replica (20s on a bad day) to Elasticsearch (60–300ms). Enabled hybrid search: BM25, metadata filters, and vector similarity in one index
- Trained a logistic regression to predict which candidates would respond to recruiter outreach — three features, doubled response rate from 20% to 40%
- Built a recommendation engine for a two-sided recruiting marketplace using neural collaborative filtering: content-based features handle cold start, collaborative filtering takes over as interaction data accumulates
Data Scientist Oct 2016 — Apr 2018
B23 · McLean, VA
- Built an ETL pipeline aggregating millions of points-of-interest from disparate sources for predictive foot-traffic analysis, sold to hedge funds
- Automated transfer of hundreds of terabytes of imagery between AWS and Snowball Edge devices for the US Navy, replacing a process that involved burning thousands of DVDs
Software Engineer Jun 2013 — Oct 2016
Agilex / Accenture Federal Services · Chantilly, VA
- Developed a semantic search application for matching intelligence reporting with collection requirements via latent semantic indexing, optimizing average query speed by 10x
