I'm Arslan Mumtaz, a software engineer who builds GoHighLevel systems that capture every lead and keep customers coming back: speed-to-lead, recall, retention, AI agents and custom integrations.
Most GoHighLevel builders stop where the platform stops. Because I'm a software engineer (BS Software Engineering, FAST-NUCES) and work as a Senior CRM Developer, I write custom code against the GoHighLevel API and webhooks whenever a business needs something the platform can't do natively, so the system fits the business instead of the other way around.
CRM Build & Migration
Full GoHighLevel setup from scratch, or a clean migration off spreadsheets and legacy tools — pipelines, custom fields, and permissions built around how your team actually sells.
Speed-to-Lead Systems
Missed-call text-back, instant quote engines, and lead routing that responds in seconds instead of hours — because response time is the single biggest lever on close rate.
Retention & Renewal Automation
Recall sequences, renewal countdowns, and churn-detection triggers that keep revenue from quietly leaking out the back of the business.
Workflow & Funnel Design
End-to-end automation logic — nurture sequences, booking funnels, review generation, and cross-sell triggers — mapped to your actual customer journey, not a generic template.
AI Agents & Custom Integrations
Conversational AI, knowledge bases, RAG and voice agents, n8n, Make and Zapier workflows, and custom API and webhook code where GoHighLevel falls short.
Every build is documented end to end: the starting point, the pipeline, what stays human, and the results.
What does a GoHighLevel expert do?
A GoHighLevel expert designs and builds the CRM, pipelines, workflows, calendars, SMS and email automation, funnels and integrations inside GoHighLevel, so a business captures every lead and follows up automatically. Arslan Mumtaz also writes custom code against the GoHighLevel API for anything the platform can't do natively.
Which industries do you build GoHighLevel systems for?
Service businesses, with documented builds for dental and medical clinics, med spas, chiropractic and physiotherapy clinics, veterinary clinics, law firms, insurance agencies, HVAC and plumbing, cleaning companies, building and pest inspection, property management, auto dealerships, fitness studios and restaurants.
Can you migrate us to GoHighLevel from another CRM or spreadsheets?
Yes. A CRM build or migration covers pipelines, custom fields, tags, permissions and moving existing contacts, built around how your team actually sells rather than a generic template.
What if GoHighLevel can't do something we need?
As a software engineer, Arslan writes the missing piece against the GoHighLevel API and webhooks, for example matching records across systems or calculating recall dates, then hands back to normal GoHighLevel workflows your team can still see and edit.
Do you build AI features in GoHighLevel?
Yes: conversational AI, knowledge bases, RAG agents and voice agents, plus AI steps in n8n workflows, such as classifying or summarising enquiries.
How does a project start?
With a free 30-minute call, followed by an audit that maps your current workflow and shows where automation pays for itself. Then design, build and test against real scenarios, launch, and tuning on live data.
Where are you based, and do you work with international clients?
Arslan Mumtaz is based in Lahore, Pakistan, and works remotely with clients worldwide, including businesses in the United States and Australia.
