About Me

With 13+ years in production systems engineering and a deep focus on applied AI, I build the platforms that turn AI capabilities into enterprise reality. Multi-agent orchestration systems, RAG architectures for enterprise knowledge bases, and intelligent assistants that solve complex business problems at scale.

My background in enterprise environments—where reliability, security, and compliance are non-negotiable—shapes everything I build. I've led cross-functional investigations across engineering and product teams, run stakeholder syncs with senior executives, and translated complex technical work into clear business outcomes. I bring that same production mindset to AI: well-tested code, robust API integrations with OpenAI and Anthropic, and systems architected for real-world deployment.

What I Build

Portfolio & Case Studies

Enterprise AI Infrastructure

Python • OpenAI API • Anthropic API • CUDA • LM Studio

Designed and deployed production AI infrastructure supporting both local and cloud LLM providers. Custom Python bridges connect LM Studio, OpenAI, and Anthropic APIs with MCP servers, enabling advanced tool integration and enterprise-grade AI capabilities.

About Lex

Lex Gaines

AI Engineer & Solutions Architect

I spent seven years as a senior systems engineer at FreeWheel, a Comcast company, building and supporting enterprise-scale ad-tech infrastructure. I led cross-functional investigations coordinating across engineering, product, and client teams. I automated reporting workflows with Python and pandas, built diagnostic tooling that became go-to resources for the broader engineering team, and ran biweekly stakeholder syncs translating technical complexity into clear business language for senior leadership.

Now I apply that enterprise production mindset to AI full-time. I design multi-agent orchestration platforms, build RAG pipelines for enterprise knowledge bases, and develop intelligent assistants that solve real business problems. I work with LangChain, LangGraph, OpenAI, and Anthropic APIs, and I ship with the rigor that comes from 13 years in environments where systems have to work at scale. I believe great technology is measured not by its sophistication, but by how effectively it solves actual problems.
