What I'm looking for

Looking for a Head/VP/Director of Engineering or CTO-track role leading product engineering teams, scaling SaaS platforms, improving execution, and building AI-enabled systems with measurable business impact.

I am a Head of Engineering and technology leader with 25+ years of experience across product engineering, scalable SaaS platforms, AI-enabled systems, enterprise architecture, cloud modernization, data flows, CRM ecosystems, and high-volume revenue-critical platforms.

Most recently, I led a distributed engineering and technology organization of roughly 25 core team members, scaling to 40 to 45 based on business demand. My scope included software engineering, QA, platform, IT, reporting, project management, architecture, cloud infrastructure, and business-critical systems supporting more than 600K users.

I have led customer-facing B2C platforms and partner-facing B2B travel commerce platforms, including pricing, commission, transaction, product selection, CRM, payment, and reporting workflows. I also launched a production AI-powered outbound voice sales platform that scaled daily interactions from roughly 900 to 18,000 and generated $200K in first-month revenue.

My leadership style is hands-on, business-focused, and execution-oriented. I enjoy improving engineering output, building accountable teams, strengthening quality standards, modernizing platforms, and aligning technology roadmaps with growth, customer experience, reliability, and operational efficiency.
