Aaron Mefford

Fractional CTO | Data Platform & AI Transformation Leader

About Me

I help growth-stage and mid-market companies build scalable, AI-ready data and technology platforms while strengthening engineering leadership and execution. With over 15 years of experience as a hands-on technical leader and architect, I’ve led data platform modernization, cloud architecture, and AI/ML infrastructure initiatives in regulated and high-growth environments. I bring deep expertise in designing lakehouse architectures, event-driven systems, and production-grade data pipelines, combined with a track record of building and scaling high-performing engineering teams. As a Fractional CTO, I partner with leadership teams to define technical strategy, improve delivery predictability, and implement AI-enabled ways of working that drive real business outcomes. I’m comfortable operating at both the strategic and hands-on level — whether that means shaping platform architecture, mentoring senior engineers, or helping organizations adopt modern data and AI practices without adding unnecessary complexity. I’ve worked across healthcare and other regulated industries, giving me strong experience with governance, compliance, security, and building systems that scale reliably. I’m particularly passionate about helping companies move from fragmented or legacy systems to clean, composable, AI-native platforms. I’m currently open to fractional CTO, technical advisory, and platform strategy engagements.
