What I'm looking for

I’m looking to build production AI agent systems end-to-end—design through deployment—in a startup-paced, async remote environment, with hands-on ownership and measurable impact on real users.

I’m a full-stack AI engineer who builds AI-powered products end-to-end—from intelligent agent pipelines to production-ready web interfaces. At Forest AI, I develop AI agents using Mastra, owning everything from agent testing infrastructure to shipping AI capabilities to real users in async remote environments.

My work focuses on hands-on AI agent development beyond simple GPT wrappers, including a simulated customer AI (Mastra + ElevenLabs) to test claim pipelines, and a retrieval-augmented AI gateway using Pinecone plus Langfuse tracing to improve LLM accuracy across benchmark workflows. I also optimized low-latency vector retrieval pipelines (about 60ms p50, near 100% benchmark success), and previously improved campaign creation efficiency by 30%, reduced re-renders by 40% with Zustand, and boosted LLM-based session accuracy by 95% by fixing session recording/transcript alignment bugs.
