Rizwan Ullah

I'm looking for remote contract or full-time work with product teams in the US, UK, EU, Canada or Australia. I'm happy to own delivery end to end: architecture, mobile apps (Flutter, native iOS and Android), FastAPI backends, store release, monitoring and support. I work 12 pm to 9 pm Pakistan time and can stretch later for US overlap. At Curiologix, I designed and lead Xeboki, a multi-tenant cloud point-of-sale platform, and a family of seven SaaS products. Xeboki brings together POS apps, a web shop, and an API and SDK, with each business using a separate Firebase project. I also built the wider Xeboki product family, including Xe Chat for AI support and Xe Launchpad for SaaS billing, alongside one account and one developer API. The platform also includes more than 2,200 free web tools. For Awaan (Dubai Media) and ADtv (Abu Dhabi Media), I delivered live TV and on-demand apps for mobile and TV platforms, with HLS, DRM, and subscriptions. I’ve also delivered marketplace apps and e-commerce stores for international clients. Earlier, at Palmchip, I built web applications across every tier and integrated Salesforce with ASP.NET. At Crewlogix Technologies, I built ASP.NET and Visual Basic applications, improved performance by refactoring legacy code, and led a real-time data analytics application. I'm currently one of the developers on a live food-ordering platform that runs 15+ UK restaurant brands from one codebase, including Gatley Tandoori, The Grubfellas, Burger & Co and Cleo's Nashville Kitchen: iOS (Swift) and Android (Kotlin) apps, web ordering on Firebase, an Android POS and a browser POS, with Stripe 3D Secure payments and Nash delivery. The same streaming codebase behind Awaan also powers Ayn (Oman Ministry of Information), SABC+ (South African Broadcasting Corporation) and 51 Kuwait. Other live client apps include U'GO Pros (service marketplace), Minti (recruitment), Shire Rewards (loyalty), The Wave Clock and StepUp Pedometer.
