Shaun Geer
Grounded in research. Focused on delivery.
I started in research at Harvard, Los Alamos, and UC Davis, building patented genomics analysis pipelines for HIV vaccine work and mapping radicalization dynamics in online hate networks. I've worked in product and strategy across AI infrastructure, privacy-preserving computation, and frontier tech.
Most of my work happens at the handoffs between disciplines: research to product, engineering to regulation, technical to strategy. There is commonly friction in these transitions. That's where I've been most useful.

Independent Projects
Solo Project · Multi-Agent · Gemini · Lobster Trap
Federated AML Investigation
- ·The wedge: §314(b) authorizes cross-bank AML information sharing but banks rarely operationalize it. Built the privacy-preserving primitives — differential privacy, signed audit chains, role-typed agents — that make it usable.
- ·Architecture: 6 AI agents across 3 trust domains with differential-privacy budgeted aggregates, Ed25519-signed envelope chains, and a custom Lobster Trap policy pack.
- ·Market comp: Verafin → Nasdaq $2.75B (2020), for the non-private version of cross-institution AML.
Team Project · Python · OpenRouter
PatientPunk
- ·Patient signal: Self-reports on Reddit contain treatment signal absent from clinical literature, especially for long COVID and ME/CFS.
- ·AI extraction: Converts unstructured patient posts into structured, MeSH/SNOMED-mapped research data using sentiment analysis and LLM extraction.
- ·Research-ready: Patient-reported data organized into SQL databases for research use.
Personal Project · Next.js · Web Audio API
EMDR / ART Self-Guided Experience
- ·Privacy-first: EMDR, ART, meditation, and bilateral stimulation. No backend, no accounts, no data collection.
- ·Local state: All state is local and session-scoped.
- ·Safety-focused: Distress scores gate entry, pace processing rounds, and trigger a grounding protocol if distress spikes.
- ·Deployed: emdr-green.vercel.app
Personal Project · Python · Claude API
CRIT
- ·API normalization: Gathers game ownership and statistics across three different APIs and normalizes them into one unified dataset.
- ·LLM context: Unified library fed as context to Claude for a game recommendation.
- ·Responsive: Response streams in real-time, making reasoning visible as it arrives.
- ·UX pattern: Explores streaming LLM output as a decision-support pattern.
Open-Source Tool · Python · Gemini · Ollama
Local Gemini Code Review
- ·Multi-provider: Code-review runner that posts the same prompt to OpenRouter, the Gemini API, or a local Ollama server. No vendor lock-in; the same workflow runs offline against a local model when API access is unavailable.
- ·Empirical tuning: Default sampling temperature retuned after observing a confidently-wrong Gemini hallucination on the runner's own diff. Failure mode and decision documented in the runbook.
- ·Operational runbook: Codifies accept/decline heuristics for code-review findings and a decline contract that prevents the next iteration from re-surfacing the same false positive.

Contributor Onboarding Research
- ·Brief: Identify friction points in the contributor onboarding process and recommend improvements.
- ·Finding: Undocumented selection criteria, not onboarding design.
- ·Deliverable: Synthesis report with pathway redesign recommendations.
- ·Methods: Semi-structured interviews, thematic analysis.
Community Research · Interview Study
Artist Community: Interview Research
- ·Question: Retention in an art-focused community of 1,000+.
- ·Archetypes: Surfaced 3 distinct user archetypes with different motivations.
- ·Deliverable: Archetype classification, retention model, and scaling recommendations.
- ·Effect: Community grew from 1,000 to 10,000+ following these and other recommendations.
Methodology
Qualitative Research Guides
- ·Guides: Research question development, interview design, thematic analysis, and survey design.
- ·Framework: Based on Braun and Clarke; includes quantitative analysis for survey outputs.
- ·Audience: Cross-functional teams building a research practice without a dedicated researcher.
