Admin Panel
Ali built a custom full-featured admin dashboard for our app, and the experience working with him was excellent from start to finish. He was highly responsive, proactive in proposing solutions, and consistently gave clear scope estimates upfront so I always knew what to expect. He communicated proactively about status, details, and different options, offered thoughtful suggestions whenever issues came up, and collaborated smoothly with the main app developer. The admin panel shipped clean with great functionality: multilingual support, role-based permissions, and clean handling of media uploads across audio, video, and images. Any issues were fixed quickly within a day. It was a great experience working with Ali and I'm looking forward to our next project together. Thank you Ali. Highly recommend!

Job Success
Lahore, Pakistan - 4:22 am local time
I’m a Top Rated Upwork developer with 100% Job Success, 120+ completed projects, 2,900+ Upwork hours, and 10+ years of full-stack engineering experience building real-world applications for healthcare, fintech, e-commerce, real estate, booking systems, AI tools, and business platforms.
🚀 Business value I focus on
My goal is not just to write code. My goal is to help you turn technical work into measurable business value: faster launches, smoother user experiences, lower operational costs, better internal workflows, scalable architecture, and software that can support paying users, staff, admins, and long-term growth.
✅ What I can help you build:
- SaaS MVPs and production web apps that can launch faster and scale cleanly
- AI-powered dashboards, chatbots, and internal tools that reduce manual work
- Healthcare and telehealth platforms with secure, role-based workflows
- React / Next.js frontends focused on usability, speed, and conversion
- Node.js / NestJS / Express backends designed for performance and maintainability
- Admin dashboards, customer portals, and multi-role systems that improve team efficiency
- Stripe, PayPal, subscriptions, and third-party API integrations that support monetization
- AWS deployment, Docker, CI/CD, performance optimization, and long-term maintenance
- Bug fixing, scaling, and takeover of existing React/Node.js codebases without creating more technical debt
🏥 Healthcare & Telehealth Platforms
Built systems like Instant Consult and Instant Touch, including patient, doctor, admin, and PMS portals, appointment booking, video consultation flows, APIs, AWS deployment, role-based access, reminders, inventory workflows, and reporting. For telehealth platforms, I have also worked with custom WebRTC-based video consultation flows, helping reduce dependency on expensive per-minute third-party video services like Twilio and making high daily video-call volume more cost-efficient to operate at scale.
🤖 AI-Powered Applications
Built practical AI features, including RAG-based document chat apps, AI chatbots, OpenAI/GPT integrations, vector search, Qdrant, speech-to-text, text-to-speech, Groq, ElevenLabs, LangChain, and custom AI workflows. These tools help businesses automate repetitive tasks, improve knowledge access, and create smarter user experiences.
🧩 SaaS, Dashboards & Backend Systems
Built and maintained admin dashboards, customer portals, payment systems, subscription flows, REST/GraphQL APIs, role-based permissions, reporting, CMS-style admin panels, and cloud deployments. These systems help businesses manage users, content, payments, analytics, and daily operations from one reliable platform.
🛠️ Core stack
React.js, Next.js, TypeScript, JavaScript, Node.js, NestJS, Express.js, Python/FastAPI, PostgreSQL, MongoDB, MySQL, Redis, Qdrant, Firebase, Supabase, OpenAI API, LangChain, AWS, Docker, Stripe, PayPal, WebRTC.
💡 What makes my work different
I do not just complete tickets, I think through product flow, architecture, edge cases, scalability, performance, security, user experience, cost-efficiency, and business impact.
Clients usually hire me when they need someone who can take ownership, communicate clearly, solve complex technical problems, improve existing systems, and ship reliable software without unnecessary delays or technical debt.
Whether you are building a new SaaS MVP, improving an existing React/Node.js app, adding AI features, automating operations, reducing infrastructure costs, or scaling a production platform, I can help you plan, build, deploy, and maintain it properly.
Send me a message, and I’ll help you choose the cleanest technical path forward.
