With 15+ years of development experience, I handle projects from planning through launch and ongoing maintenance. I work independently and write the code myself, so you communicate directly with the person building your product. Problems I can help you solve: • Your store is slow, difficult to use, or missing functionality. I improve Shopify and WooCommerce stores, customize themes, build apps, and connect payments, subscriptions, shipping, and fulfillment systems. I also work with Magento, BigCommerce, and PrestaShop. • You need to launch a product or improve an existing platform. I build SaaS MVPs, customer portals, dashboards, and APIs, and add features to existing applications using React, Next.js, Vue.js, Node.js, Laravel, and Python. • Your business needs an iOS or Android app. I develop mobile applications with React Native, Flutter, Swift, or Kotlin and connect them to your backend, business systems, and cloud services. • Your team spends too much time on repetitive tasks or searching for information. I build AI assistants that answer questions from your business documents, automate document processing, and connect your existing tools through APIs and workflows. • Your software has recurring bugs or is becoming difficult to maintain. I investigate failures, improve performance, resolve technical debt, and stabilize existing systems. You can hire me for a specific fix, a complete build, or ongoing development. I prioritize clear communication, maintainable code, and software that supports your daily operations. Tell me what you are building or what is not working, and I will help you define a practical next step. less -

Senior .NET & AI Engineer | RAG · Multi-Agent · Azure OpenAI | Preferred FreelancerIndiaI'm a Preferred Freelancer (invitation-only tier, fewer than 3% of accounts) and Senior Software Engineer with 4 to 5 years of hands-on experience building production-grade AI systems, cloud-native backends, and intelligent automation pipelines.

My core expertise sits at the intersection of .NET and C# engineering and modern AI and LLM integration — a combination that lets me ship systems that are both architecturally solid and genuinely intelligent. On the AI side, I've built and deployed real-world applications using Azure OpenAI, Semantic Kernel, and multi-agent orchestration frameworks. This includes a multilingual document translation system for UN field operations handling Arabic, French, English, and Spanish; a RAG chatbot with real-time tool calling over enterprise data; a natural language analytics dashboard querying SQL Server and Cosmos DB; and a 12-agent stock analysis pipeline producing BUY, SELL, or HOLD decisions with entry, target, and stop-loss levels. These aren't demos. They're production systems with measurable business impact. On the backend side, I specialize in ASP.NET Core APIs, Azure Functions, event-driven architectures, and distributed system patterns like SAGA, CQRS, and event sourcing. I've also delivered Azure infrastructure and DevOps projects — multi-region deployments, AKS cluster management, cost optimization, and CI/CD pipelines. I hold a Microsoft Azure Developer Associate certification and work daily with Cosmos DB, SQL Server, Redis, and the broader Azure ecosystem. I also build on the frontend when needed, working with React and Angular, so I can own a feature end to end without handing things off mid-stream. What sets me apart is that I don't just integrate AI as a feature. I architect it as a system. I think in pipelines, agents, retrieval strategies, and evaluation loops. I've worked with ReAct-style agents, agentic RAG, RAGAS evaluation frameworks, and fine-tuning workflows using LoRA, QLoRA, and DPO. I understand the difference between a demo that impresses and a system that holds up in production. I work independently, communicate clearly, and take real ownership of what I build. I'm looking for clients who want serious engineering applied to serious problems — whether that's LLM pipelines, AI-native backends, cloud architecture, or intelligent automation. If you want someone who can think through the architecture, write the code, and ship something that actually works, let's connect. Let's build something worth building. less -
