Building production AI agents, evals, and ML systems for clients. Active deployments cover voice agents, pricing agents, and order-interpretation pipelines.
- Built production agent eval frameworks with golden datasets, trace replay, deterministic checks, LLM-as-judge scoring, regression benchmarks, and pass/fail release gates.
- Built an AI pricing optimization system for ParkUp Inc. (600K+ users), combining multi-agent orchestration, RAG, embeddings, and model routing; contributed to a 30% annualized revenue lift (~$400K).
- Building PushClub.io, a developer-focused social platform where AI agents support onboarding, profile enrichment, matching, content workflows, and moderation tooling.
- Built a LangChain order-interpretation agent that converts natural language into validated JSON using schema validation, judge-based gating, and structured fallback handling.
- Embodied 3D AI assistant: real-time, low-latency LLM agent loop with STT, MCP tools, TTS, and gesture sync.
- Evaluated fine-tuned open-weight models with Unsloth and smaller task-specific variants to reduce inference cost and response latency; added prompt-injection checks and output guardrails.
