Islamabad, Pakistan - 5:59 pm local time

Struggling with manual work, disconnected tools, and 𝗔𝗣𝗜𝘀 that won't talk to each other? That's the problem I solve. I build 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 and 𝗶𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀 that connect your apps, move your data where it needs to go, and quietly run your operations in the background, so your team stops doing copy-paste busywork and gets that time back.

Hi, I'm 𝗦𝗮𝗶𝗳. Over the last 5+ years and 50+ projects, I've learned that the hard part of automation isn't building the first workflow. It's building one that's still running six months later without anyone babysitting it. That's what I focus on.

Most automation work falls apart the first time something unexpected happens: an API times out, a field changes, a webhook fires twice. I build for those moments from the start, with proper error handling, retries, and monitoring, so the system recovers on its own instead of silently breaking and leaving you to find out from an angry customer.

𝗛𝗲𝗿𝗲'𝘀 𝘁𝗵𝗲 𝗸𝗶𝗻𝗱 𝗼𝗳 𝘄𝗼𝗿𝗸 𝗜 𝗱𝗼:

➜ Automating the repetitive processes that eat your week, from lead handling and data entry to reporting and follow-ups, usually with n8n (self-hosted or cloud) so you own the system and aren't locked into rising subscription fees.
➜ Connecting tools that don't natively integrate. If your Shopify store, your CRM, your billing, and your spreadsheets all live in separate worlds, I build the bridges between them using their APIs, webhooks, and OAuth, so data flows automatically instead of by hand.
➜ Building AI chatbots and assistants that actually plug into your business, qualifying leads, handling support, and pulling from your real data instead of giving generic answers.
Setting up CRM automation that keeps records clean and pipelines moving, so your sales team spends time selling instead of updating fields.
➜ Writing scrapers and data pipelines that collect, clean, and deliver the information you need on a schedule.

How this plays out in practice: a client came to me jumping between platforms every day to pull leads, enrich them, and add them to their CRM by hand. It was eating hours daily and mistakes were slipping through. I built one workflow that runs the whole thing automatically in the background, from capture to enrichment to a clean CRM record, with checks that catch bad data before it lands. They stopped thinking about it entirely, which is the point. Good automation is the kind you forget is even there.

𝗔 𝗳𝗲𝘄 𝘁𝗵𝗶𝗻𝗴𝘀 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝗵𝗮𝘃𝗲 𝗰𝗼𝗺𝗲 𝗯𝗮𝗰𝗸 𝘁𝗼 𝗺𝗲 𝗳𝗼𝗿 𝘀𝗽𝗲𝗰𝗶𝗳𝗶𝗰𝗮𝗹𝗹𝘆:

➜ Diagnosing and fixing broken API connections fast. This is repeat work for me, people hire me once to fix it and again the next time something breaks, because I find the actual cause instead of patching symptoms.
➜ Standing up self-hosted n8n properly, with SSL, Docker, and a reverse proxy, so it's secure and production-ready rather than a fragile test setup.
➜ Cutting manual workload dramatically. One pipeline replaced over 100 hours of manual work a month for a client.

On the technical side, I work mostly with n8n, Make, and Zapier for automation; OpenAI for the AI pieces; and Next.js, Python, Node.js, and PostgreSQL when a project needs custom development beyond off-the-shelf tools. I'm comfortable across the stack, which means I can build the whole system end to end instead of handing you half of it.

The way I work is simple. I'll tell you upfront what's realistic, keep you updated without you having to chase me, and walk you through whatever I build so your team can actually run it. No black boxes.
I tend to work best with founders, agencies, and growing e-commerce or SaaS teams, the kind of people who've outgrown doing everything manually but don't want to hire a full engineering team to fix it.

And if you're not technical, that's fine, most of my clients aren't. You don't need to understand how it works under the hood. You tell me what's slowing you down, I handle the build, and I hand it back in plain language with a short walkthrough so you and your team feel in control of it. If something needs adjusting later, I'm reachable and I don't disappear after delivery.

If you've got a process that's draining your time or two systems that refuse to talk to each other, send me a message describing it. I'll tell you honestly whether I can help and how I'd approach it.
