About

Founders bring me in when their product is growing, but their frontend isn’t keeping up. You might be dealing with: * A messy MVP codebase that’s starting to crack * Slowing development velocity and rising bug counts * Unclear UI patterns and inconsistent user experience * No time (or budget) to hire a full frontend team yet That’s where I come in. I act as a hands-on frontend architect—bringing structure, scalability, and clarity to your product. I help you set technical direction, clean up your codebase, ship faster, and make your early hires more effective. All without the cost or commitment of a full-time lead engineer. What I bring to the table: * Frontend architecture that scales with your team and product * Real-world experience in React, TypeScript, and modern frameworks * Fast, clean builds that are easy to maintain and hand off * Guidance for hiring, onboarding, and mentoring early devs * A fractional model that gives you senior-level expertise, flexibly Think of me as your startup’s secret weapon for building frontend right the first time.
