Full Stack Developer — AI-Powered Music Platform MVP (Next.js + Supabase + Anthropic API)
Really great experience working with Hashir and the Brainbox team on the design for UNSIGNED. From the start the communication was clear and they were quick to respond, which made the whole thing easy. They took the time to properly understand the brand and what I was going for, and the work came back clean, on-brief and to a high standard.
What stood out most was how helpful they were throughout. Nothing was ever a problem, and they often made changes and tweaks for free rather than nickel-and-diming every small request. That kind of attitude makes a real difference when you're building something and still figuring bits out as you go. They were patient, happy to iterate until it was right, and genuinely invested in getting it good rather than just getting it done.
Professional from start to finish, and a pleasure to work with. Would happily work with them again, and already am on the main build. Highly recommended to anyone looking for a team that actually cares about the work.

HubSpot → GoHighLevel CRM Migration (70k Contacts + Automations)
We had an excellent experience working with Saad and his team on the migration of our CRM from HubSpot to GoHighLevel.
From day one, they provided outstanding guidance, clear communication, detailed reporting, and consistent follow-up throughout the entire project. Their responsiveness and attention to detail gave us confidence that every aspect of the migration was being handled professionally.
What truly stood out was that they went beyond the technical migration itself. They took the time to understand our business, identified opportunities to reduce costs and optimize our systems, in order to improve our sales. Their strategic recommendations delivered value far beyond the original scope of the project.
The migration was smooth, well-organized, and completed with a high level of expertise. We were so pleased with the quality of their work and ongoing support that we decided to continue working with them for the maintenance, optimization, and management of our GoHighLevel CRM moving forward.
We highly recommend them to any business looking for a knowledgeable, proactive, and results-driven CRM partner. Thank you for your exceptional support and partnership.

GoHighLevel / REI Reply Automation Expert Needed (Workflow & CRM Build-Out)
Saad and his team are the rare implementation partner who can handle complex, multi‑step systems without dropping the ball. This project involved a lot of moving parts (multi‑branch journeys, compliance constraints, voice/SMS logic, and CRM automation), and he stayed thoughtful and methodical the whole way through. He doesn’t just ‘do what you say’ – they took the time to understand the underlying process, proposes cleaner ways to structure it, and clearly explains tradeoffs so you can make the right call.
Communication was solid, documentation was clear, and when we hit unexpected edge cases they debugged quickly and transparently instead of getting defensive. If you need someone to build or refine a serious GoHighLevel/REI Reply workflow system – not just a simple funnel – I highly recommend

Full Stack AI developer for AI coaching app
Great working with Saad and his team. They delivered solid full-stack + AI development and used AI-assisted development responsibly, which saved both time and cost. We launched the MVP quickly and got it live with smooth communication throughout.
About Saad
Full-Stack AI & CRM Developer | React, Next.js, HighLevel, HubSpot
100%
Job Success
Islamabad, Pakistan - 4:24 pm local time
If your last developer took 6 months and delivered nothing, or your HubSpot or HighLevel account is leaking leads and nothing talks to each other — that's exactly the kind of mess I fix.
⚡ AI-Powered SaaS & MVP Development
I ship AI SaaS MVPs in 4–8 weeks using React, Next.js, Supabase, Node.js, and OpenAI/Claude API integration. Full authentication, admin dashboards, Stripe billing, and AI features built in from day one — not bolted on later. Web application development that's ready for real users, not a demo.
🔄 CRM Automation, HubSpot & HighLevel Integration, Data Migration
Broken workflows, leaking leads, disconnected tools — I rebuild CRM systems properly. Recently completed a CRM data migration of 70,000 contacts from HubSpot to HighLevel and rebuilt the entire automation workflow from scratch. I handle HubSpot workflows, HubSpot API integrations, HighLevel automations and snapshots, Salesforce, and custom CRM logic when off-the-shelf doesn't cut it.
🔗 API Development & Integration
Complex API integrations that keep breaking? Stripe, REST, GraphQL, webhook chains, HubSpot API, HighLevel API — I build API integrations that hold up in production. Clean data flow between systems, proper error handling, and nothing silently failing at 2am. Custom API development with Python and FastAPI when you need your own backend.
🤖 AI Integration & Automation
I integrate OpenAI API, Claude, and other LLMs into existing products — AI chatbots, document processing, workflow automation, and AI features that create real business value, not gimmicks.
📱 Mobile + Web Apps
One codebase, every platform. React Native + Expo with shared business logic, deployed to iOS and Android with the same quality standards as my web builds.
What clients say:
⭐ "Saad and his team are the rare implementation partner who can handle complex, multi-step systems without dropping the ball."
⭐ "I've worked with a lot of development teams, but Saad and his team are different. They think."
⭐ "Saad goes above and beyond. He understands the problems and provides the best solutions."
How I work:
✅ AI-assisted development (Claude Code, Cursor) — startup speed, senior-level architecture, every line reviewed and tested by hand
✅ Fixed-price milestones or clearly scoped hourly engagements
✅ Loom walkthrough with every delivery, clear async communication, no disappearing mid-project
Stack: React, Next.js, Node.js, TypeScript, JavaScript, Python, FastAPI, Supabase, PostgreSQL, Firebase, AWS, Stripe, Tailwind CSS, OpenAI API, Claude, HubSpot, HighLevel
