Habib U.

I am a Senior Full Stack & AI Developer with deep expertise across the complete .NET ecosystem, Node.js, Next.js, React, Angular, Blazor, cloud platforms (AWS, Azure, GCP), and AI-powered application development solutions. As a Top Rated Plus freelancer with 8,000+ hours on Upwork and over a decade of hands-on experience, I specialize in building end-to-end software solutions across web, mobile, and desktop platforms. My work focuses on production-grade systems that are scalable, secure, and aligned with real business workflows. I do not build demos. I build systems that businesses rely on. --- My Skills & Expertise Full Stack Application Development I design and develop complete applications from architecture to deployment, covering backend logic, frontend interfaces, APIs, databases, and cloud infrastructure. I take ownership of the full lifecycle rather than isolated tasks. .NET & Microsoft Ecosystem I work across the entire .NET stack to build enterprise-level applications using clean architecture, modular design, and long-term maintainability principles. AI-Powered Application Development I integrate AI directly into applications to enhance automation, decision-making, search, and user interaction (AI used as a functional system component, not a surface feature). AI Agents, Chatbots & RAG Systems I build intelligent agents and conversational systems using Retrieval-Augmented Generation for context-aware responses, internal tools, and customer-facing platforms. Cloud Architecture & DevOps I deploy and manage applications across Azure, AWS, and GCP with a focus on scalability, cost control, security, and production stability. Automation & Workflow Orchestration I automate business processes and AI workflows using modern automation platforms to reduce manual work and improve operational efficiency. Database Design & Data Handling I design efficient, scalable data models and manage structured and unstructured data for high-performance applications. --- Core Technology Stack Backend & Application Frameworks • .NET Framework • .NET Core • ASP .NET • ASP .NET MVC • ASP .NET Web API • Node.js • Next.js • Blazor Server • Blazor WebAssembly • .NET MAUI (cross-platform mobile and desktop apps) • C# (primary language), JavaScript, TypeScript Frontend Technologies • Angular • Blazor • React • HTML, CSS, JavaScript (modern standards and performance-focused UI) AI & Intelligent Systems • OpenAI APIs • AI-powered application development • AI Agents & Chatbots • RAG (Retrieval-Augmented Generation) systems • LangChain • LangGraph • Vector databases • Context-aware automation and intelligent search Cloud Platforms & Infrastructure • Microsoft Azure • Amazon Web Services (AWS) • Google Cloud Platform (GCP) • CI/CD pipelines • Containerized deployments • Cloud security and monitoring Automation & Integration Tools • n8n • Zapier • Microsoft Power Automate • API integrations and system orchestration Databases & Data Storage • SQL Server • MongoDB • Relational and NoSQL database architecture • Performance optimization and data integrity Additional Languages & Tools • JavaScript, TypeScript, Tailwind CSS • Python (for AI, automation, and integrations) --- What I Deliver • End-to-end Web, Mobile, and Desktop Applications • Full Stack .NET Solutions with clean architecture • AI-powered platforms, agents, and chatbots • Cloud-native, scalable applications • Secure APIs and third-party integrations • Database-driven systems built for performance and scale --- I offer free consultation for custom application ideas and enjoy working with founders and teams to refine requirements, design architecture, and turn ideas into production-ready systems. I stand behind my work. If you are not satisfied, I provide a complete money-back guarantee with no questions asked. I am a problem solver and a doer.
