Hire the Best Payment Gateway Integration Specialists
in the United Arab Emirates

With a 100% Job Success Score, $50K+ earned, 61 jobs completed, and 5,900+ hours on Upwork, I build secure, scalable fintech and digital banking platforms, along with AI agents and SaaS products for startups and growing businesses. My work spans core banking systems and payment platforms that handle real transactions, LLM/AI agents that automate business workflows, and full-stack SaaS products including food delivery and restaurant management platforms built for real users at scale. What I build: • Digital Banking & Fintech Platforms — neobank SaaS, KYC/AML, wallets, ledgers, payment gateway integrations (Stripe, PayPal, ACH) • POS Terminal Solutions — Android POS, card processing, payment terminal apps • AI Agents & LLM Automation — custom agents, workflow automation, AI-powered SaaS tools • SaaS Platforms — B2B tools, food delivery & restaurant management systems • Full-Stack Web & Mobile Apps — React, Next.js, React Native • Secure REST APIs, microservices, and cloud-native architecture • Blockchain-integrated applications (on request) Tech stack: Frontend: React, Next.js, React Native, TypeScript Backend: Node.js, Python, Java, Golang AI/Automation: LLM integration, AI agent frameworks, workflow automation Database: PostgreSQL, MySQL, MongoDB Cloud/DevOps: AWS, Docker, Kubernetes, CI/CD I build with security and PCI-DSS-aware practices from day one, so your product whether it's a fintech platform, an AI agent, or a SaaS tool is ready for real users and real transactions, not just a demo. Let's talk about your project. Message me to get started.

I build, rebuild, fix, and optimize business-critical websites where design, performance, ecommerce, CRM, payments, tracking, APIs, and backend workflows all need to work properly. With $500K+ earned and 700+ completed Upwork jobs, I bring senior-level ownership to website and ecommerce projects — not just page building, but full business system implementation. I help businesses with: • WordPress website design, redesign, development, and performance optimization • WooCommerce stores, product pages, checkout flows, payment gateways, and custom ecommerce features • Shopify builds, custom themes, Shopify Flow automation, and integrations • Webflow development, Figma-to-Webflow builds, CMS setup, and responsive design • HubSpot CRM setup, pipelines, workflows, forms, tracking, and automation • Website speed optimization, Core Web Vitals, migrations, and security hardening • GA4, Google Tag Manager, Google Ads conversion tracking, Meta Pixel, and reporting • API integrations, Stripe, Zapier, Make, Calendly, and third-party tool connections • Laravel/PHP custom portals, dashboards, and business applications • Troubleshooting broken websites, failed integrations, unreliable tracking, and messy CRM setups What makes me different: I am not a page-builder freelancer. I combine frontend development, backend systems, ecommerce, CRM, automation, tracking, and technical problem-solving into one ownership role. This means I can build the website, connect your payments, set up your CRM, automate your lead flow, fix performance issues, and make sure your entire business system works from end to end. Typical projects I handle: • Full website rebuilds for established businesses (corporate, B2B, SaaS, agencies, medical, real estate) • WooCommerce and ecommerce builds with custom product logic, subscriptions, and payment flows • WordPress rescue projects — broken sites, Elementor bloat, plugin conflicts, legacy PHP, migrations • Webflow and Figma-to-build projects with responsive design and CMS • Shopify premium builds with automation, CRM, and tracking integrations • Agency long-term development partnerships and white-label work • Custom Laravel/PHP portals, marketplaces, and business dashboards • Technical SEO, site speed, and performance optimization My goal is simple: make your website and business systems clean, fast, reliable, secure, and built for growth.

Full-Stack & AI Developer, NestJS Developer, Node.js Expert, React.js Developer, Next.js Developer, LLM Integration Specialist, API Integration, Backend Developer, TypeScript, RAG, GraphQL, REST API Developer. Hi, I'm Syed. I'm a Full-Stack and AI Developer with 8+ years building web and mobile apps that ship and scale. My core strength is backend work in NestJS and Node.js, paired with clean React, Next.js, and Angular front ends. I also build AI/LLM features and handle the messy integration work most projects need, including payments (Stripe, MyFatoorah), CRM and ERP systems (HubSpot, NetSuite), messaging (Twilio), and real-time data. 𝐎𝐧 𝐭𝐡𝐞 𝐀𝐈 𝐬𝐢𝐝𝐞, I build things people actually use in production: chatbots, RAG pipelines, document analysis and data extraction, and structured JSON output from LLMs. I've also set up self-hosted, on-premises models with Ollama for clients who need their data to stay private. Over the years, I've worked with startups and established companies across fintech, e-commerce, healthcare, ride and transport services, and management platforms. I've delivered solo and as part of senior engineering teams, and I'm comfortable working to tight deadlines without letting code quality slip.
