Currently Building

Finance × Engineering × AI

Staff Accountant at Ortho Molecular Products by day, AI engineer and full-stack developer by craft. With a B.S. in Computer Science from Pitt and hands-on experience building LLM orchestration engines, RAG pipelines, and production cloud systems. I bridge the gap between business operations and cutting-edge technology. The rare hybrid who speaks both GAAP and GPU.

What I Do

Staff Accountant at Ortho Molecular Products in Barrington, where I prepare and maintain financial and business transactions grounded in accounting principles and theory. I support the Fast Close process through reconciliations, assist with internal audits to ensure accurate financial reporting, and maintain fixed asset schedules with depreciation tracking. I also compile data for annual reviews and corporate tax filings, handle sales tax remittals, and continuously identify process improvements to streamline department operations.

Outside of work, I build production-ready AI applications, full-stack systems, and data-driven tools. From LLM orchestration engines and multi-agent systems to mobile apps and browser automation, I bring a rare combination of financial acumen and engineering depth.

About Me

I'm a Staff Accountant at Ortho Molecular Products with a B.S. in Computer Science from the University of Pittsburgh, and I never stopped building. While I handle financial reporting and operations during the day, I continuously ship AI-powered applications, full-stack systems, and multi-agent platforms on my own time. I'm the person who automates the spreadsheet, then builds the AI that replaces the automation. As AI reshapes every industry, having someone who understands both the numbers and the neural nets isn't just useful, it's a competitive advantage. Finance, engineering, AI: I don't pick one lane.
