Agency overflow, shipped under your brand. You keep the client. I deliver the product — same stack as StackMatch and HireGraph, both live.

White-Label Full-Stack Developer White-label development · 2 live systems in production

about.md

Builder first — agency-ready

// builder first

I'm a full-stack developer who owns products end to end — architecture, implementation, deployment. StackMatch and HireGraph are live systems with real users and data pipelines, not portfolio demos.

I also lead product at Jisheng, which means I can pull in additional developers when a white-label engagement outgrows a solo build — same spec, same quality bar, faster delivery.

✓ Invisible to your clients · white-label by default

// for agencies

Your brand stays client-facing — I stay behind the scenes
Start with a 1–2 week scoped sprint before committing bigger
Weekly demos of working software your team can show clients
AI, data pipelines, full-stack — same stack behind my own products
Not interested in: spec-only consulting, unpaid trials, equity-only deals

start here

1–2 week scoped sprint

The usual first engagement: one feature, an MVP slice, or overflow on a live client project. Clear spec, weekly demo, white-label handoff. Scale to a longer build only if the sprint lands.

mode: solo

Solo build

MVPs, feature work, overflow sprints — I build hands-on. Best when you need one reliable developer who ships without hand-holding.

mode: team

Team build

Larger scope or tighter timelines — I lead the project and expand capacity through Jisheng. You deal with one point of contact, not a bench of freelancers.

Proof I ship — not mockups

"David shipped a working MVP in three weeks — clean code, clear communication, zero drama."

Tony Novak · 2Advanced

These are my own live products — same stack, same delivery standard I bring to white-label agency work: Next.js, PostgreSQL, AI pipelines, production deploys.

process.yml

How an engagement runs

pipeline: white-label-engagement ✓ 4/4 passed

✓

scope

~1–2 days

Scope aligned to your client's brief — you stay client-facing, I stay invisible. Clear spec before build starts, no guessing after deposit.

✓

build

weekly demos

Working software early and often — demos your team can show the client, not slide decks or one big reveal at the end.

✓

ship

deployed + tested

Handoff under your brand — repo, docs, deploy. No portfolio credit unless you want it. White-label by default.

✓

scale

when needed

Project outgrows solo capacity? I expand the team through Jisheng — same lead, same quality bar, without you managing freelancers.

What I build with

contact.sh

Start with a 1–2 week sprint.

Send the client brief, the stack, and the deadline. I reply within 24 hours with a scoped sprint or a no. Typical start: this week. You keep the client relationship; I deliver the product.
