Problems agencies hire us to solve
Our freelancer disappeared mid-project.
One consistent builder who knows your accounts, on a monthly plan with agreed reply times.
We keep fixing work we paid for.
Everything is tested before delivery and handed over with a Loom walkthrough you can show your team.
We need GHL, n8n, and AI voice. That's three hires.
One partner who builds across GoHighLevel, n8n, Make, Vapi, Retell, and APIs.
Explaining every task takes longer than doing it.
We learn your snapshots, naming, and standards once, then work from short task notes.

What clients say
“The automation has significantly improved the efficiency of our business processes.”

“I recently worked with Muhammad to build out a custom automation for my business, and I couldn't be more pleased with the experience from start to finish. Throughout the project, Muhammad was consistently reliable — deadlines were met, communication was clear, and I never had to chase for updates. What really stood out was how thoughtful and understanding he was when it came to grasping exactly what I needed. He took the time to truly understand my business processes rather than just executing instructions at face value. Muhammad was also highly responsive to my requests, accommodating adjustments along the way without any fuss. That level of flexibility made the whole process feel genuinely collaborative. The end result has made a real difference to how we operate. The automation has significantly improved the efficiency of our business processes, saving us time and reducing the kind of manual work that used to slow us down. I would highly recommend Muhammad to anyone looking for a skilled, dependable, and professional automation specialist. I'll certainly be working with him again.”

“Muhammad is great to work with. He helped us build and improve our automation systems in GoHighLevel, including workflows, pipelines, and integrations with tools like Make.com and ReadyMode. He understands both the technical side and the business side, which made a big difference. He was able to troubleshoot issues quickly and also suggest better ways to structure things so they work properly long term. Very reliable, communicates well, and knows what he’s doing. I’d definitely recommend him for CRM and automation work.”

“I had an excellent experience working with Muhammad on building out my Make.com to CRM automation. From start to finish, he was incredibly responsive, detail-oriented, and professional. What really stood out was his patience, he took the time to clearly explain how everything works, making sure I fully understood the system rather than just setting it up and leaving me guessing. His attention to detail ensured that everything was configured properly and running smoothly”

Who builds your work
Muhammad Aoosjah
Founder · HighLevel Certified Admin
I build the systems that make sure every lead gets a fast reply, gets qualified, and gets booked: GoHighLevel accounts, n8n and Make workflows, CRM integrations, and AI voice agents on Vapi and Retell.
Agencies and businesses in healthcare, real estate, fitness, and e-commerce already rely on systems I've built. When you work with OJStack, you work with me directly. No account managers, no hand-offs.
Tell me where leads are slipping through, and I'll show you exactly what I would build to fix it.
Questions agencies ask
What is white-label GoHighLevel support?
White-label GHL support means we build workflows, funnels, automations, and integrations inside your clients' sub-accounts, and you deliver the work under your agency's brand. Your clients never see OJStack.
How much does a white-label GHL developer cost?
OJStack retainers start at $800 per month for one active task at a time, and $1,500 per month for two. Large builds such as full migrations are quoted separately. There is no hourly tracking to manage.
How does the active-task retainer work?
You add tasks to a shared board in any order. We work on a set number of tasks at the same time, and start the next one as soon as one is delivered. You get a steady flow of finished work without counting hours.
Will you contact our clients?
No. We only talk to your clients if you ask us to, and we never market to them. This is written into our agreement.
Can we test you before committing to a retainer?
Yes. Most agencies start with one real task from their backlog as a paid test, usually $150 to $300, delivered in two to four days with a Loom walkthrough.
Do you work with med spa and clinic agencies?
Yes. Much of our work has been for clinic and healthcare clients, including missed-call text-back, appointment reminders, review requests, rebooking reminders, and patient reactivation in GoHighLevel.
Send us one task from your backlog
We build it as a paid test, delivered in two to four days with a Loom walkthrough. If you like the work, we talk about a plan.
