What I'm looking for

I’m looking to build AI/ML and LLM-powered enterprise products—integrating OpenAI APIs, RAG, and chatbots into real workflows—while applying strong full-stack engineering in C#/.NET and cloud environments to improve productivity and reliability.

I’m a Senior Software Engineer with 17+ years of experience building scalable enterprise applications across web, desktop, and cloud environments. Over 5+ years, I’ve designed and integrated AI/ML-powered solutions—Generative AI applications, ChatGPT-based assistants, LLM integrations, intelligent automation workflows, and AI-driven productivity tools.

I’m hands-on across the stack: C#, .NET, Angular, Vue.js, Python, REST APIs, cloud platforms, and databases, and I build AI-enabled applications using OpenAI APIs, prompt engineering, Retrieval-Augmented Generation (RAG), vector databases, and chatbot architectures. I’m passionate about leveraging Artificial Intelligence to improve business processes, automate workflows, and create intelligent software products.
