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

Most GoHighLevel and HubSpot systems are built to function, not to convert. Leads fall through the cracks, follow-ups stop too early, attribution breaks, and sales opportunities get lost. I help agencies, real estate professionals, coaches, consultants, healthcare businesses, roofing companies, and service-based businesses build high-performing HubSpot & GoHighLevel CRM systems that automate lead management, appointment booking, customer follow-up, sales pipelines, lead nurturing, and marketing operations from first touchpoint to closed client. My approach goes beyond basic workflow setup. I build scalable, conversion-focused HubSpot/GoHighLevel infrastructures designed to improve lead response speed, streamline operations, eliminate manual tasks, optimize customer journeys, and create reliable automation systems businesses can actually scale with.
