I build GoHighLevel systems, AI automations, CRM workflows, and custom SaaS platforms that capture leads, book appointments, and convert prospects, without anyone managing them manually.
If your agency or business is still running on manual follow-ups, disconnected tools, or a CRM nobody trusts.
I fix that. And when your automation needs a custom home to live in, I build that too.⚡
GOHIGHLEVEL (GHL) — MY CORE SPECIALTY
✔ Full GHL account & sub-account setup, onboarding & white-label branding
✔ Snapshot creation, cloning & deployment — niche-ready systems for fast client launches
✔ High-converting funnels, landing pages, opt-ins, upsells & checkout flows
✔ CRM pipeline configuration — lead scoring, tagging, deal progression & follow-up logic
✔ Multi-channel automations — email, SMS, voice drops, missed-call text-back
✔ Appointment scheduling — calendar setup, reminders, Google/Outlook sync
✔ Reputation management — automated review request flows & brand trust building
✔ GHL AI conversation automation — lead qualification bots & smart follow-ups
✔ White-label SaaS builds — resellable snapshots your agency can deploy in days
🔄 WORKFLOW AUTOMATION
✔ n8n, Make com, and Zapier — multi-step workflows built for real business conditions
✔ Lead capture → nurture → scheduling → conversion running on autopilot
✔ API and webhook integrations — if two platforms exist, I can connect them
✔ Airtable and Google Sheets automation with custom scripts and dashboards
🤖 AI AGENT DEVELOPMENT

✔ Email deliverability setup — domain auth, SMTP config, inbox optimization

🖥️ CUSTOM SaaS & WEB DEVELOPMENT
Sometimes automation needs a custom platform to live in — I build that too.
✔ SaaS MVP Development — idea to working product, fast and clean
✔ React & Next.js — modern, fast frontends and client dashboards
✔ Node.js & REST APIs — scalable backends that connect to any tool or CRM
✔ Custom client portals — white-label dashboards built on top of your GHL or automation stack
✔ Webhook & API architecture — clean data pipelines between your platforms
✔ Database design — structured, reliable data that doesn't break under load
Whether you need a landing page, an internal ops dashboard, or a full SaaS product, I build it to integrate seamlessly with your automation stack from day one.

💡 A startup or operator who needs a custom web app and the workflows to power it
💡 WHY CLIENTS KEEP COMING BACK100% Job Success Score across 50+ completed projects and 1,500+ hours isn't luck — it's a process. I don't hand off a workflow and disappear.
Every system I build is documented, tested, and designed so your team can operate it independently. When your business grows and needs something new, I'm still here.
No broken handoffs. No mystery logic. No ghosting.Just clean builds, clear communication, and automations still running months after delivery.
