About Me
I help startups and scale-ups turn engineering into a strategic advantage. With 9+ years across FinTech, HealthTech, eCommerce and SaaS, I build and scale engineering quality functions that reduce delivery risk, accelerate deployment cycles, and increase product reliability, especially in regulated and high-growth environments.
I operate at the intersection of engineering, product, and business. I've supported market expansions, prepared organizations for compliance (SOC2), worked directly with clients in presales and consulting contexts, and built internal tools that enable better decision-making across teams.
As a hands-on technical leader, I combine deep implementation work (automation, CI/CD, AI agents, DevOps) with strategic thinking, aligning quality initiatives with business goals, customer impact, and revenue outcomes.
Whether acting as a transformation partner, forward-deployed engineering leader, or AI enablement consultant, my focus is simple: build systems that scale with the company.
I frequently embed within teams during critical transformation phases, working directly with engineers, product leaders, and stakeholders to deliver high-impact changes quickly.
