You will get your broken n8n workflow, webhook, API, and data mapping fixed
Project details
Is your n8n workflow failing, returning errors, missing data, or not triggering correctly? I will diagnose the root cause, repair the broken workflow, and test it properly so it runs reliably again.
I can help with failed nodes, webhook issues, API authentication errors, incorrect JSON or data mapping, HTTP Request problems, duplicate executions, missing values, database connections, and workflows that stop unexpectedly.
Instead of applying a temporary patch, I review the workflow logic, identify what caused the failure, fix the agreed issues, and verify the expected input and output. Depending on your package, I can also optimize the workflow and provide clear fix documentation.
Please contact me before ordering if the workflow contains multiple complex errors, custom code, or undocumented third-party APIs. Never send passwords or API keys in the initial requirements; secure access can be shared after the project begins.

LinkedIn Sales Navigator Lead Gen Coach and Implementor
Working with Sarfraz has been an absolute pleasure from start to finish. As a LinkedIn Sales Navigator Lead Gen Coach and Implementor, Sarfraz brought a level of expertise, dedication, and professionalism that truly exceeded our expectations. From day one, he demonstrated a deep understanding of LinkedIn's platform and how to leverage it strategically to generate high-quality leads that aligned perfectly with our target audience.
Sarfraz took the time to understand our business goals, our ideal client profile, and the nuances of our industry before crafting a tailored outreach strategy. His approach was methodical and data-driven — he didn't just send generic connection requests, but instead built thoughtful, personalized messaging sequences that resonated with prospects and drove real engagement. The results spoke for themselves.
What truly set Sarfraz apart was his proactive communication. He provided regular updates, detailed reports, and was always available to answer questions or adjust strategy based on new information. He never had to be chased down for updates — he was consistently one step ahead, which made working with him feel effortless and stress-free.
His knowledge of LinkedIn Sales Navigator is second to none. He knew exactly how to use advanced filters, saved searches, and lead lists to identify and target the right people at the right companies. He also brought creative ideas to the table that we hadn't considered, and each suggestion was well-reasoned and backed by experience.
Beyond his technical skills, Sarfraz is a true professional. He's reliable, honest, and genuinely invested in the success of his clients. He treated our project as if it were his own business, and that level of care and ownership is rare to find. I would recommend Sarfraz without hesitation to any company looking to supercharge their LinkedIn lead generation efforts. We will absolutely be working with him again.

If orders are being missed, supplier issues are caught too late, pricing or product updates keep falling behind, or your team is still doing too much manually across Shopify, Walmart, eBay and spreadsheets, that's where I come in.
Send me the messy part of your eCommerce operation. I'll tell you what I would get under control first, what can be simplified, and what should be automated.
A little more about me:
I don't just keep stores updated.
I take ownership of the operation behind them.
That can include:
• Orders, fulfillment, returns, refunds and replacements
• Supplier and factory coordination
• Stock availability and operational follow-ups
• Pricing, margins and product management
• Shopify operations, plus Walmart and eBay
• Customer service workflows and escalations
• Reporting, dashboards and recurring operational controls
• SOPs, documentation and process improvement
• Team coordination and day-to-day follow-through
Then I look for the repetitive work that should not stay manual.
I build practical store automations using n8n, APIs, webhooks, Google Sheets, databases and AI where it actually improves the operation.
That can mean automating customer or order workflows, internal alerts, reporting, follow-ups, data movement, repetitive admin work or the handoffs between different systems.
I don't force AI into a workflow just because AI is available.
If simple automation or database logic is more reliable, that's what I use.
The goal isn't to build something clever.
The goal is to make the business easier to operate, easier to control and less dependent on repetitive manual work.
If you need someone who can understand what is happening across the store, take ownership of the day-to-day operation and then improve the systems behind it, send me a message.
