What I'm looking for

I'm looking to build scalable backend, platform, and AI systems where I can own architecture through production, automate complex workflows, and improve reliability and performance.

At MedImpact Healthcare Systems, I design, deploy, and operate business-critical backend services for enterprise Pharmacy Benefit Management platforms, translating complex healthcare and insurance workflows into scalable APIs, distributed processing, and automation.

Across MedImpact, ToXSL Technologies, and Illuminz, I’ve built multi-tenant SaaS platforms, high-performance web applications, REST APIs, and full-stack products with Go, Node.js, TypeScript, React, Redis, and SQL databases. More recently, I’ve built LARA, an AI assistant platform using LangChain, LangGraph, RAG, MCP, tool calling, semantic search, and OpenAI-compatible LLMs to automate engineering and business workflows.
