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.
HighLevel certification and skills badges
Certified Admin, plus HighLevel skills badges across AI voice, funnels, ads and more.
Why OJStack exists
Leads get lost after they arrive
Most businesses don't have a lead problem. They have a follow-up problem: enquiries sit in a pipeline until someone remembers them. OJStack exists to build the systems that handle that part.
Agencies need builders they can rely on
Agencies sell GoHighLevel to their clients, then need someone who can actually build, test and maintain it. OJStack is that technical delivery, under the agency's brand.
How clients work with OJStack
Agencies. A paid test task from your backlog, then a monthly plan with a set number of active tasks. Everything delivered under your brand.
Businesses. A GHL audit or a 30-minute call, then a fixed-price build, then optional monthly care so the system keeps working.
Direct communication
Updates by Slack, WhatsApp, or email, with Loom walkthroughs on delivery. Replies within 24 hours on working days. You always know what is being built and where it stands.
Reliable technical delivery
Process before tools. We map how your leads move from enquiry to booking before we choose what to build.
Tested, then handed over. Every delivery is tested end to end and comes with documentation and a walkthrough video.
Honest about results. We describe what we built and what changed. We do not invent numbers.
