I build automation and AI systems that turn manual, unscalable business processes into reliable, running infrastructure. I'm currently building an AI-powered customer outreach system for a B2B software company — the core engine pulls account context and drafts personalized emails for human approval before send, and is now in integration and testing to get it running reliably end-to-end. I'm also building browser automation (Playwright) to eliminate repetitive manual data entry in an internal system. Earlier, at a global CPG manufacturing plant, I revived a dormant industrial IoT system that was collecting data but driving zero decisions. I rebuilt the dashboards from floor-team input, added real-time threshold alerting, and built the alert-routing pipeline into the plant's existing tools — then quantified and presented the case for scaled predictive maintenance: a projected $40M/year in savings from reduced downtime and scrap, validated with plant leadership. I work primarily in Python, n8n, Microsoft Power Automate, and LLM APIs (Claude, GPT), with a growing focus on workflow automation and AI-assisted operations tooling. If you need someone to look at a manual process and come back with a working system — not just a recommendation — that's the work I want.

With a PhD in Machine Learning and over 16 years of experience in both research and industry, I bring a wealth of knowledge and expertise to my work.
