Vetted A/B Testing Professionals

“Built a production voice-first fitness coaching/logging system ("Hey Coach") that routes headphone audio, transcribes speech, and uses LLMs to parse workouts into structured data with human-in-the-loop QA and A/B-tested improvements. Also brings a commercial background: led capital markets at a Series A fintech securing $250M+ in commitments and drove early GTM at WorkHQ.com, landing its first Fortune 500 customer.”

“Lifecycle/CRM marketer from Churchome who led a mobile app onboarding and re-engagement program using behavior-based segmentation, in-app/push messaging, and AI-assisted chat. Drove ~20% lift in early-stage engagement, improved 30-day retention, and reduced support load through automated chat flows and rapid A/B-driven iteration.”

“AI/ML engineer who led Impacter AI’s production deployment of a specialized outreach LLM (CharmedLLM) fine-tuned on GPT-4.1, cutting API costs ~40% while boosting outreach effectiveness ~60%. Built the supporting MLOps and data infrastructure (MLflow, Kubernetes, PySpark, Kafka) and has agentic AI experience from University of Dayton, using LangChain + RAG and vector search (Pinecone) to improve reliability and reduce hallucinations.”

“GenAI/LLM engineer with production experience at Allstate building an end-to-end document intelligence workflow for insurance operations—automating document intake, classification, and risk signal extraction. Emphasizes high-reliability design for regulated/high-stakes outputs using schema enforcement, confidence thresholds, validation rules, and human-in-the-loop routing, with metric-driven offline evaluation and production monitoring.”

“Unity game developer who shipped a major core-mechanic change (“bowler quality”) for a bowling-sim game, using Firebase A/B testing and analytics to find the right difficulty/monetization balance and adding targeted onboarding to address player confusion. Also refactored a Photon-based multiplayer matchmaking/initialization “waterfall,” fixing a long-standing async host-selection bug that caused infinite loading.”

“Performance marketer who built and scaled digital acquisition for GovVacationRewards.com from limited performance marketing to a multi-channel system across Google/MS/Facebook, using geo-fencing, video + search remarketing, and funnel optimization. Delivered major efficiency gains (sub-$8 CPA) and growth to 10K+ monthly enrollments on $75–80K spend, while also improving brand reputation and tying results to subscription-driven ROAS (reported up to ~16x). Prefers contract/freelance roles with an option to convert full-time.”

“Built production automations and LLM/RAG prototypes spanning enterprise and personal use cases: cleaned a 5TB Akamai storage estate via n8n + legacy REST APIs (20–25% deletion, cost savings) and developed an internal Qdrant-backed RAG chatbot evaluated with automated scoring plus user feedback. Also prototypes latency-sensitive agentic tools (e.g., automated hotline calling) and designs guardrails against prompt injection for email/PDF processing workflows.”
