Hi, I'm Razi. I build systems that never let a lead go cold.

GoHighLevel expert and AI automation developer, 4 years in. I build the CRMs, AI agents, and automations that answer every lead, follow up every estimate, and keep calendars full. For agencies and service businesses across the US, UK, Canada, and Australia.

CASE STUDIES

Work that runs in production

Most of my work lives inside client CRMs, so instead of pretty mockups you get the problem, the build, and the numbers.

TRUEWIRE · HOME-SERVICES PLATFORM, US
~1 hourto deploy the full system to each new client, instead of a rebuild

An AI front desk platform a US company now deploys to its own clients

The situation

Baker Hinton's company, TrueWire, needed a productized AI lead system it could roll out across service contractors: missed-call recovery, an AI agent that answers and books, and human handoff that respects how a real crew works. SMS was the production channel, so A2P 10DLC registration had to clear first, and most builds stall there for weeks.

What I built

  • AI text front desk that qualifies leads and never quotes prices
  • Works identically on web chat and SMS, so it was tested live before carrier approval
  • Missed-call text-back firing in about 25 seconds
  • 3-tier human handoff: sales, dispatch, owner-only, each routed differently
  • Self-maintaining pipeline, review automation, weekly owner digest, per-contact kill switch

The outcome

A2P brand and campaign registration approved on the first attempt. Delivered as a sterile master snapshot with a full documentation suite: deploying to a new contractor takes about an hour. A $1,200 project that became an ongoing onboarding and maintenance arm.

LAND AI · US AI LEAD-GEN STARTUP
46+active client sub-accounts on one standardized platform, 1.49M+ records behind it

The GHL platform layer behind a multi-tenant AI startup

The situation

Land AI, serving real estate investors and realtors, needed its GHL layer to behave like a product: identical automations across every client, new sub-accounts provisioned fast, and data flowing reliably from AI processing into the right pipeline stage.

What I built

  • The GHL platform layer: automations, snapshot standardization, sub-account provisioning
  • The integration contract moving AI outputs into GHL pipelines, triggers, and reporting
  • Standardized structure across 46+ active sub-accounts sitting on 1.49M+ records

The outcome

One standardized platform instead of 46 hand-built accounts. New client provisioning became routine instead of a project.

JOSE T. · SENIOR HOME CARE, FLORIDA
100%of milestones approved on first review, most within 24 hours

A lead-cadence engine the client made his written standard

The situation

A Florida home care agency was buying referral leads that went cold: no systematic follow-up, no consent tracking on SMS, and a call-tracking integration that let junk calls into the CRM while blocking real ones.

What I built

  • 5 automated cadences to exact spec, including a 90-day contact cadence and a 2-year nurture pool
  • 43 SMS messages consent-gated across 13 live workflows for TCPA safety
  • CallRail-to-CRM lead filter rebuilt and verified read-only against 7 historical runs before go-live
  • Every delivery shipped with a verification table: expected behavior next to actual

The outcome

Three engagement batches, every milestone approved on first review. The client made my verification table his written standard for all future work. His full review is below.

MINDFLOURISH · UK WELLNESS EDUCATION
1,500+members served by the program this system runs, across an 18-month engagement

When no-code hits a ceiling, I write the code

The situation

MindFlourish needed what most agencies quote a team for: a custom quiz app, a personalized sales funnel, subscription billing with trials, course delivery, and humane cancel and refund flows. None of it buildable with page builders.

What I built

  • Custom React quiz app that scores visitors and routes each to a personalized sales page
  • 3-variant funnel in GHL: separate sales pages, order forms, and course versions per outcome
  • Stripe subscriptions with 7-day trials, one-click lifetime upgrade, automated refund logic
  • Drip-unlocked trial courses and an 8-stage automated pipeline from quiz to completion

The outcome

An 18-month engagement across 4 separate contracts, all five-star reviewed, supporting a program serving 1,500+ members. Gordon's words are in the reviews below.

8 FIGURE AGENCY · US CONSULTANCY
1,000+agency clients served by the systems I engineered as Lead CRM Strategist

Lead CRM engineer inside a consultancy scaling agencies to $1M to $10M+ ARR

The situation

8 Figure Agency needed its client-facing GHL systems built and standardized at the scale of a 1,000+ agency client base: every end-client expecting a working system, fast.

What I built

  • Snapshots deployed across agency end-clients, SaaS mode and white-label configuration
  • Pipeline architecture with custom stage automations and full account migrations
  • Cross-platform sync between GHL, Notion, and Slack
  • Custom code where the platform ran out: Python scripts, webhook handling, portal styling

The outcome

Repeatable builds instead of one-off projects. The snapshot pattern meant a new end-client got a working system in a fraction of the original build time. 1+ year as Lead CRM Strategist and Automations Engineer.

WHAT I DO

If one of these sounds like your week, that is what I fix

"Leads go cold before anyone calls back."

Missed-call text-back, speed-to-lead automations, and AI front desks that answer in seconds, qualify politely, and book the calendar.

"Every new client takes a week to onboard."

Sterile master snapshots, SaaS mode, and provisioning workflows that turn your agency's delivery into a one-hour deploy.

"We want AI answering, but it cannot embarrass us."

Conversation AI and voice agents (Retell, Vapi) with tier routing, guardrails on what they may say, and a kill switch on every contact.

"A2P is blocking our SMS."

Brand and campaign registration done end to end. My last registration cleared on the first attempt. Carrier timelines stay with the carriers, and I will tell you that honestly.

"Our tools do not talk to each other."

Make, n8n, and Zapier scenarios, direct REST API integrations, webhooks with HMAC validation, and the data mapping in between.

"We hit the ceiling of no-code."

I have a web developer background. When the platform runs out, I drop into code and write the fix.

THE ROAD HERE

Web Developer, NICAT

Built web interfaces at the National Incubation Center for Aerospace Technologies, while deep in undergrad and client work.

2024

React at NESCOM, full-stack certified, all-in on Upwork

HOW I WORK

Built like an engineer, not a gig

01

Diagnose before building

I start with your process, not a tool list. If there is a faster or simpler way to get the same outcome, I say so before you spend money on the wrong build.

02

Deliver in draft

Everything ships in draft for your review first. You always know exactly what you are approving before anything touches your live account.

03

Verify against reality

Bigger deliveries ship with a verification table: expected behavior next to actual behavior, checked against historical runs. One client made it his written standard.

CLIENT REVIEWS

Reviews you can verify, word for word

What a year of working together looks like

Spencer has run projects with me for about a year. What he calls out: attention to detail, follow-through on finishing projects, and honest communication about time and focus. Unscripted, in his own words.

"Razi did excellent work building out our GHL + Make.com lead automation system. He was methodical and transparent throughout — everything was delivered in draft for my review, with detailed verification on every piece before anything went live, so I always knew exactly what I was approving. When he hit an architectural decision around data security, he flagged it and laid out options instead of just building past it, which I really appreciated. He also walked me through a live end-to-end test so I could confirm the whole system worked with my own eyes. Communication was clear and professional the entire time. I'd hire him again for future automation work."

We worked in team meetings daily and he delivered on a consistent cadence. Deliverables landed daily. We have a fast moving team and it's not a place tech people can hide. Razi kept up, was self directed and performed. I'll work with him again."

"He goes above and beyond, advanced GHL Admin, API, Scripting, coding skills and he just kept on pulling more skills out to get the project done. Top skill: SMARTS and EASY to work with. He gives you 100% of his attention and once he is clear, does miracles, plus has positive radiance around him. He honestly told us, Keap is not my top skill but I know what needs to be done to help you move to GHL. Because he has advanced API/Coding skills move became possible. All lists, automations, historical records and more are in GHL before deadline. Highly recommend Razi as top expect on Upwork!"

ABOUT

The short version

I wrote my first code in 2015, modding games and pulling software apart to see how it worked. By 2021 the hobby had become a career: a Computer Science degree and my first paid web development clients in the US and UK. Client work kept pulling me toward the same problem: businesses drowning in manual follow-up. In 2022 that pulled me into CRM and automation engineering, and GoHighLevel became my primary platform.

Since then: 100+ GHL sub-accounts shipped, a year plus as Lead CRM Strategist and Automations Engineer at 8 Figure Agency, and the GHL platform layer of Land AI, a US AI lead-gen startup running 46+ client sub-accounts. Along the way I founded Olventra, my automation studio, and completed a Computer Science degree.

The practical stuff. I am based in Rawalpindi, Pakistan, and my working day is 6pm to 3am local, which is the full US Eastern business day. I have worked US hours for years: your Slack, your standups, your timezone. Async messages get a reply within 24 hours, usually much faster.

One honest line: I am not a visual designer and I will not pretend to be one. I build systems that work, document them properly, and tell you when something you asked for has a better path.
