Hire the Best Payment Gateway Integration Specialists
in the United Kingdom

Is your CRM, payment gateway, ERP, or eCommerce platform losing data every time it syncs? I integrate the systems your business runs on: Stripe, HubSpot, Shopify, QuickBooks, Salesforce, and 50+ POS and payment platforms, so they exchange data reliably, even under real transaction volume. My work covers API integration, application integration, business process automation, REST API, SOAP API, JSON API, and webhook integration, along with the solution architecture decisions that keep those connections stable once real traffic hits them. 11+ years designing and scaling enterprise integrations for companies including Mastercard and Vodafone. Message me what's breaking, or invite me to your job post, and I'll send back a short Loom on exactly how I'd approach it. No call required. WHAT'S ACTUALLY BREAKING (AND WHY) It's rarely bad theory. It's systems that were never built for the volume they're now under. The patterns I see most often: A legacy pipeline nobody wants to touch, because nobody's sure what happens if they do. POS, CRM, and ERP systems that are "connected" but quietly losing packets between each other: Stripe API billing syncs, HubSpot marketing API integrations, and Shopify order flows included. Failures nobody catches until a customer does, because there's no real logging, retries, or observability (Datadog, Prometheus) in place. If none of that sounds like your problem, I'm probably not the right fit, and that's fine. If it does, worth a conversation. INTEGRATIONS COMPLETED ERP to Stripe payment bridge, rebuilt to handle millions in monthly transactions with zero downtime Automated reconciliation between Stripe billing events and ERP ledger records Shopify to HubSpot customer and order sync, rebuilt event-driven for peak traffic Webhook-based Shopify order events feeding HubSpot marketing automation in real time 50+ POS terminals aggregated into a single forecasting engine POS-to-inventory sync across 50+ terminals to prevent stockouts Cross-terminal data reconciliation to catch drift before it reached the forecasting model I don't do coding tests or theater. I'll tell you honestly what's scoped, what it'll take, and what's actually worth doing, even if that means telling you less work is the right call.

Most people can design a Wix site. I’m the one you call when you need that site to actually work like a high-end software application. With a Master’s in Computer Science and 500+ successfully delivered projects, I bridge the gap between "pretty design" and "powerful architecture." As a Wix Legend Partner, I specialize in the "impossible" - turning complex business logic into smooth, scalable realities using Wix Velo. What I actually do for your business: * Custom Velo Development: Custom Velo Development: I build bespoke user dashboards, complex booking engines, and dynamic web apps that standard Wix apps can't handle. * Deep API Integrations: I sync your site seamlessly with Salesforce, HubSpot, Stripe, or any external database you rely on. * Advanced CMS Architecture: I structure your data for high-performance, ensuring your site stays fast even with thousands of entries. * Workflow Automation: I write the code that handles the "boring stuff," reducing your manual overhead so you can focus on growth. Why me? I don’t just "drag and drop." I write clean, efficient code backed by a decade of engineering experience. I’m obsessed with performance, security, and making sure your site is ready to scale the moment you are. If you’re tired of hearing "Wix can’t do that," let’s chat. I’d love to show you that it can. - Tayyba Jehangir
