- AmrapFounder, Tech LeadHEALTH AND WELLNESSNovember 2024 - February 2026 (1 year and 3 months)New York, NY, USACofounded Amrap, a real-time AI personal trainer that builds personalized strength routines and coaches users live on the gym floor through voice and video.- Designed and built the end-to-end product: voice-first iOS app and a multi-agent backend that generates high-personalization routines and coaches workouts in real time, calling out weights and reps, teaching technique, and answering exercise questions on the spot.- Architected an agent orchestration layer combining LLM reasoning with deterministic and LLM-based validators, cutting hallucinations by 95% and engineered patterns so the remaining 5% wouldn’t degrade the UX.- Tuned the system for in-gym latency: sub-2-second voice responses during coaching and full routine generation in 30 to 60 seconds, with on-the-fly adaptation to the exact equipment available and to user feedback mid-session.- Built the platform on clean-architecture principles using a microservice setup on GKE (Kubernetes), with Swift on the client, LiveKit for low-latency voice, PydanticAI for agent adapters, React for web, and SQL plus Firestore for persistence.- Took the product from zero to a few paying users. We didn’t figure out distribution before I left.
