Over the years, I’ve designed cloud-native platforms, distributed applications, Web API services, microservices, and enterprise backend systems for complex environments. My current focus is on Artificial Intelligence, AI Development, AI Agent Development, and practical Automation for business workflows. As an AI Developer, I build systems that connect LLMs, RAG, Azure AI Services, APIs, and business logic into stable products. The goal is not just to add AI features, but to create Operational value: fewer manual tasks, better decisions, faster delivery, and cleaner internal processes. As an AI Developer, I work across the full product lifecycle: discovery, architecture, backend logic, API integration, cloud setup, testing, deployment, and long-term support. I use .NET Core, Microsoft Azure, Orleans, RESTful architecture, and CI/CD to make sure every solution is secure, maintainable, and ready for real users. A strong part of my work is AI Development for SaaS products and enterprise platforms. I design Artificial Intelligence features, AI agents, AI assistants, copilots, workflow Automation, and API-connected systems that support real Operational needs. My background in .NET Core and distributed architecture helps me build high-concurrency applications that stay stable as usage grows. I also help teams modernize existing systems. As an AI Developer, I can review architecture, improve backend performance, connect AI services, build custom Automation, and turn fragmented workflows into one clear Operational process. 🛠️ Technical Skills C# & .NET Core Microsoft Azure & Cloud Architecture Orleans Distributed Virtual Actor Framework RESTful Architecture & Web API SaaS Development & Microservices Software Architecture & Design Patterns Artificial Intelligence solution design Artificial Intelligence architecture AI Development lifecycle .NET Core architecture AI Development for enterprise systems AI Developer implementation AI Agent Development & AI assistants Retrieval Augmented Generation LLM Prompt Design Azure AI Services API Design and Integration Automation workflows Operational system architecture MAUI & Blazor Angular DevOps, Kubernetes & CI/CD Aspire 🌿 Strategic Skills Enterprise Software Architecture Planning Artificial Intelligence strategy AI Development roadmap AI Developer technical leadership Automation planning Operational workflow optimization Cloud Migration & Optimization Performance Optimization Security & GDPR Compliance Cost Optimization Agile & Scrum Team Leadership Stakeholder Communication Technical Discovery & Roadmapping TOGAF Methodology Problem Solving 🏆 Certifications Microsoft Certified: Azure AI Associate Microsoft Certified: Azure Developer Associate Microsoft Certified: Azure DevOps Expert Microsoft Certified: Azure AI Fundamentals Xamarin Certified Mobile Developer Agentic AI developer, C# ai, ai integration, ai api integration,ai integration specialist, ai agent saas, ai saas developer, ai architect, ai solution architect, ai chat bot, ai chatbot saas, open ai chatbot, full stack developer, multi-agent, ai agent automation, ai automation agency, chatbot automation,, c# developer, c# .net, .net ai, .net developer, .net fullstack, ai agent builder, ai agent n8n, ai agent crypto, ai agent automation, rag, agentic rag, agentic rag, ai engineer rag, agentic rag, full stack app developer, full stack developer ai, artificial intelligence, artificial intelligence consultant, ai llm, llm agent, ai llm developer, llm chatbot, langchain agent, ai developer langchain, llm langchain, ai agent, ai voice agent, customer service agent, web developer, azure ai, azure ai studio, azure devops, azure architect, ai engineer, prompt engineer, product engineer, ai workflow, ai workflow automation, workflow automation, orchestration, ai prompt engineer, claude prompt, ai prompt engineering, ai prompt,prompt engineer claude, open ai developer, open ai chatbot, ai models, ai integration, ai integration specialist, ai integrator, ai api integrator, ai powered, claude certified.
