Senior Audio Software Engineer specializing in real-time audio ML systems

Somerville, MA5y exp

“Startup backend engineer with unusually deep end-to-end ownership of real-time audio/ML systems. At Modulate, they rebuilt the core Audio Intelligence API used by enterprise customers like Activision, cutting latency 70% and eliminating session loss, and also independently created a data labeling platform that powered the company’s model training during a major product pivot.”

“Built and shipped a production RAG-based enterprise knowledge assistant to replace slow/inaccurate search across millions of documents, using LangChain orchestration with GPT-4/LLaMA and vector databases. Strong focus on production constraints—latency, hallucination control, and cost—using hybrid retrieval, guardrails, LLM-as-judge validation, and model routing, and has experience translating non-technical stakeholder pain points into measurable outcomes.”

“Full-stack engineer who built and owned an end-to-end real-time engineering dashboard for Medtronic robotic surgical systems, streaming high-frequency sensor/kinematic data via Python WebSockets to a React/TypeScript UI. Differentiates through performance/reliability practices (stable core vs experimental layer, observability, caching) and high-impact 3D visualization + session playback that became part of engineers' regular bench-testing workflows.”

“Software engineer with experience spanning high-scale backend systems and distributed consensus: led a 6-person team delivering a production data querying/visualization platform with major latency improvements via cursor-based pagination and streamed results. Built a RAFT-based distributed logging tool resilient to partitions and storage constraints, and at Nasuni developed FastAPI services processing multi-terabyte workloads for 500+ enterprise customers with secure API key management.”

“Full-stack engineer focused on productionizing LLM applications, including an Android privacy-policy risk summarization app (Kotlin/React Native + FastAPI + Ollama) that cut response times from ~10s to ~5–6s via batching, caching, async, and event-driven architecture. Currently at PRGX building an LLM-based legal contract clause extraction system, partnering closely with legal/procurement SMEs to create schemas, labeled datasets, and evaluation pipelines that improved accuracy from 70% to 85%. Also has experience architecting real-time voice/LLM systems with streaming microservices (Kafka, Kubernetes, gRPC/WebSockets) and an avatar chatbot pipeline (TalkingHead, Google TTS, AnythingLLM).”
