Hi, I'm Jonathan Marcus, the founder of Primary Key Solutions. I'm a senior developer and systems architect specializing in building custom solutions that make businesses run smarter, faster, and more efficiently.

I focus on turning complicated, messy workflows into clean, automated systems that are easy for teams to use and simple for leadership to trust. My background spans FileMaker development, custom software engineering, API integrations, automation, and data architecture—with particular expertise in modernizing legacy systems and connecting them to today's technology.

I build everything from lightweight tools to full enterprise platforms, including front-end dashboards, mobile workflows, and secure back-end architectures. I'm known for taking deep, complex problems and translating them into practical solutions—whether that means designing an entire database from scratch, integrating third-party services, building a React-based web interface, or creating automation that replaces hours of manual work.

I work with companies that need real results: faster workflows, cleaner data, better visibility, and systems that scale as they grow. Across healthcare, operations, finance, service industries, and internal-facing business platforms, my approach stays the same: build with clarity, automate wherever possible, and deliver tools that people actually enjoy using.
