Owner & Consultant, M.J. Koskinen LLC

Owner of M.J. Koskinen LLC, a software consulting business focused on leveraging A.I. for professional software development. Combining over fifteen years of engineering experience with nearly a decade of leadership, I help teams adopt AI-driven development practices without compromising quality, architecture, or maintainability.

Previously Director of Software Engineering at Referral Rock, where I led high-performance development teams and drove technical innovation — transforming the development pipeline, mentoring cross-functional teams, and streamlining IT infrastructure to support rapid business growth. My approach combines technical expertise with strategic business acumen, fostering a culture of innovation and continuous improvement.

Expertise in modern software architecture, cloud technologies, and AI-assisted development workflows, with a strong foundation in full-stack development and a Master's in Business Administration from George Mason University.
