Sub-Second Custom Code
No bloated page builders. I ship clean, lightweight frontends that load in under 0.8s and immediately lower your clients' Meta & TikTok ad CPA.

01 / Technical Edge
Built for speed. Designed for handoff.
Direct engineering, production-ready tracking, and a clean white-label experience your clients never have to think about.
100% Ghost White-Label
Strict confidentiality. I can hop in your Slack/Zoom wearing your agency's hat, or stay completely invisible behind the scenes.
Pixel & Conversion Ready
Every client build ships with Meta Pixel, Conversions API, GA4, and CRM webhooks structured and ready to fire.
Direct Builder Access
Zero account managers or middleman agency bloat. You send the spec directly to me, and I write the code.
02 / The No-Meeting Handoff Pipeline
A clean handoff. No calendar ping-pong.
Send the essentials.
Send over your client's brand assets, Figma file (or 2 reference sites), and target launch date. No 2-hour discovery calls required.
Review a real build.
I spin up the custom build on a private staging URL and record a quick walkthrough within 48–72 hours for rapid revisions.
Launch with confidence.
I connect the client's custom domain, verify all tracking events are firing green, and hand over the finished asset.
03 / Transparent Wholesale Rates
Clear cost. Room to grow.
Flat partner pricing lets you scope confidently, protect your margin, and deliver without adding a full-time developer.
