I build production AI automation systems for businesses that need more than a demo. My focus is making AI useful inside real operations: connecting systems, controlling what AI is allowed to do, handling failures properly, keeping state consistent, and making sure workflows remain maintainable as they grow. I come from a background in large-scale infrastructure, data systems, backend development, and operations: • Solo-managed infrastructure supporting 3,500+ active VPS instances • Architected data pipelines processing 250M+ records • Built automation that removed around 70% of repetitive management work in a large operations environment • Delivered production AI automation, workflow orchestration, LLM evaluation, messaging integrations, and secure self-hosted systems for clients Recent work has included AI-assisted real estate and legal workflows, secure production AI infrastructure, email and messaging automation, multi-model evaluation systems, and business process automation. I do not treat the AI model as the whole system. The difficult part is everything around it: integrations, permissions, state, validation, recovery, observability, and deciding where human approval belongs. I work with Python, Node.js, PHP, APIs, Linux, databases, LLMs, retrieval systems, MCP integrations, and custom orchestration. I am comfortable using an existing platform where it makes sense, or building the required components directly when a framework creates unnecessary limitations. If you need AI integrated into a real business process, especially where reliability and control matter, I can help design the architecture and build it.
