Work/White-Label Development
// stark dev · white-label & agency development

Your brand. Your client.
Our engineering.

We build the custom plugin, platform, or integration your client actually needs — and deliver it under your brand. No credits, no "powered by," no conflict. Just clean code that solves problems off-the-shelf tools never will.

// what white-label development means here

Not a theme swap. Not a plugin configuration. Custom software — built from scratch — delivered under your name.

Every project below started with a client problem no existing tool could solve — a booking system that needed a full payment lifecycle, a job board that needed to sync from an enterprise ATS, an SEO strategy that needed hundreds of pages generated automatically from live data. Off-the-shelf plugins don't do this. We write the code that does.

model 01 · agency white-label

You own the client relationship.

You present, you manage, you invoice. We build quietly in the background — under your agency name or brand. The code ships with your author credits, your domain, your identity. We never appear in client-facing deliverables unless you want us to.

model 02 · direct engagement

We're the dev team you don't have in-house.

For businesses that need custom software but don't want to hire an engineering team. We embed alongside your operation, build what you need, and hand off code you own outright — documented, validated, and deployable on your infrastructure.

// selected white-label builds

A few of the systems we've built behind the scenes.

Each one started with a client problem no off-the-shelf tool could solve. Client names withheld — these are the builds, told without the names.

// every white-label engagement includes

Not just code. A complete, handoff-ready deliverable.

🏗️

Modular architecture

No monolithic files. Every responsibility lives in its own class. Files stay under 800 lines. The plugin is easy to pick up, maintain, and extend — by us or by whoever comes next.

Validated on delivery

Every file passes PHP syntax validation and JS syntax checks before it leaves our hands. BOM detection, file size warnings, and form-nesting tests run as part of the build process. [PASS] required before handoff.

📄

Documented handoff

Context docs, changelog, state notes, and decisions logged throughout the build. You receive a complete picture of what was built, why, and what comes next — not just a zip file.

🔒

Security-first code

Nonce verification, permission checks, input sanitization, and output escaping throughout. Import/export validation rejects PHP serialized payloads. Clean uninstall policy preserves data by default.

🔌

Pluggable by design

Payment adapters, AI providers, notification recipients, email bodies — all filterable via WordPress hooks. The client can customize behavior without touching core plugin code.

🚀

WordPress standards

Custom post types, REST API endpoints, shortcodes, cron scheduling, and admin UI all follow WordPress coding and security standards. No reinventing the wheel; no fighting the platform.

// where we've done this before

Complex problems across industries.

Every one of these started with "there's no plugin that does what we need."

🏠

Home services & contractors

Booking-fee intake funnels, service qualifier flows, multi-step booking lifecycles, and job management pipelines — replacing manual quoting and phone-tag with a structured system.

👥

Staffing & workforce

ATS API integrations, live job board sync, filterable job listings with maps, and AI-powered SEO location pages generated from live data — for regional and national staffing firms.

🏘️

Property management

AppFolio sync engines, listing CPT systems, AI-generated rental descriptions, showing booking systems with multi-agent availability, and ad manager tooling. (See: ListingBridges.)

🏥

Healthcare & wellness

Patient-focused websites with custom booking flows, local SEO, and content systems built around how people actually search for care — not how practices want to present themselves.

🔒

Security & facilities

Lead generation systems, service-area targeting, local SEO infrastructure, and paid ad ecosystems for companies whose business depends on trust and local visibility.

Custom software needs

If you have a problem an off-the-shelf plugin won't solve and a client relationship that needs a custom-built answer — that's the brief we work best with. Tell us what's broken.

// our commitment to agency partners

We work for you. Your client never knows we exist.

Every line of code ships with your author credit. Every client touchpoint is yours. We don't poach clients, we don't reach out directly, and we don't advertise the relationship unless you specifically ask us to. Your client relationship is yours — permanently.

01

Your brand on every deliverable — plugin name, author, URI, all yours.

02

No client contact — all communication routes through you.

03

You own the code — full rights to everything we build for you.

04

NDA-friendly — we sign whatever your client relationship requires.

05

24–48 hour response — every message gets an answer, every sprint.

06

Validated before handoff — [PASS] required. No untested code ships.
