For agencies

Senior delivery capacity without adding another vendor layer.

I join agency projects as a direct senior developer for frontend builds, CMS integrations, performance, technical SEO and release support — with clear async communication and no sales team in the middle.

When you bring me onto a project I work as an extension of your team, not a competing vendor. That means white-label senior capacity under your brand, in your process, on your timeline — a named developer who writes the code and joins the calls you need, without the overhead of onboarding a whole shop. You keep the client relationship; I keep the delivery risk low.

I stay in my lane on purpose. I do not pitch your clients, rebrand the work as mine, or try to expand scope behind your back. Whether you need someone to own a full frontend build, cover a Next.js deadline, or take one tricky slice off an overloaded team, the arrangement is designed to make you look reliable to the people who hired you.

Why this works

Why agencies use this

You get a named senior person who writes the code, communicates directly and can protect the agency-client relationship by reducing delivery risk.

Common questions

Will you contact or pitch our client directly?+

No. I work white-label under your brand and your client relationship stays entirely yours. I am happy to join client calls as part of your team if that helps, or stay fully behind the scenes — whichever you prefer. I never solicit your clients.

How do we communicate day to day?+

Async-first, in whatever tools you already use — your Slack, your tracker, your repo. I write clear updates and demo work in visible increments so you always know status without chasing me. When a call is faster than a thread, we jump on one.

Can you cover a single deadline or one slice, not a whole project?+

Yes, that is a common way agencies use me. I can take one component, one integration or one release under pressure, or plug in for a fixed number of weeks. After a short technical intake I confirm scope and availability so you know exactly what I will deliver and by when.

I personally scope, build and ship — no account managers, no hand-offs. You work directly with the developer doing the work.
