Hello! 👋 I’m a CTO, Senior .NET Core Developer, and AI Engineer with 20+ years of experience in C#, Microsoft Azure, cloud architecture, enterprise software, and Artificial Intelligence solutions. I help companies build scalable SaaS platforms, enterprise systems, internal tools, AI assistants, AI copilots, and production-ready AI products. As an AI Developer, I combine backend engineering with AI Development, Automation, API integration, and .NET Core architecture to create reliable Operational systems that solve real business problems. 📘 About Me I’m a technical leader with deep experience in software architecture, C# development, and .NET Core systems. 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 🤝 Let’s Connect I can help you design, build, and scale intelligent software solutions using C#, .NET Core, Microsoft Azure, Artificial Intelligence (AI), AI Development, AI Agent Development, Automation, API Integration, and Chatbot Development.

Hello, I’m Jason Nhien Truong, a Senior Software Engineer and Software Architect with over 20 years of professional experience delivering reliable, maintainable software solutions for businesses across multiple industries. I specialize in C# and .NET development, Windows desktop applications, enterprise web systems, SQL databases, and Azure-based platforms. I help clients modernize legacy systems, stabilize and scale existing products, and build new applications with a strong focus on performance, usability, and long-term maintainability. I work closely with stakeholders to translate business needs into practical, well-structured technical solutions. What I offer Full-stack .NET development I work across the .NET ecosystem, from legacy ASP.NET Web Forms to modern .NET 8 APIs and microservices. I design secure, scalable backend systems with clean architecture and clear separation of concerns. Windows desktop application development I have extensive experience building and maintaining Windows desktop applications using WinForms and WPF, including MVVM-based WPF applications. I focus on responsive UI behavior, clean data binding, maintainable ViewModel design, and user-friendly workflows for business-critical desktop software. Enterprise UI with DevExpress and Telerik I have deep expertise with DevExpress and Telerik controls for WinForms and web applications. I redesign and modernize complex UIs to improve usability, consistency, and performance without breaking existing business logic.

Why work with me I bring deep technical experience, strong ownership, and a business-focused mindset. I communicate clearly, meet commitments, and build software that remains stable and maintainable over time. Availability Open to full-time or part-time engagements. Flexible with time zones for long-term projects. If you’re looking for a senior .NET engineer who can handle both backend systems and Windows desktop applications with confidence, feel free to reach out.

If your system got slower over time and nobody really knows why — that’s usually where I come in. Most developers avoid messy data, slow queries, and systems nobody wants to touch. That’s where I do my best work. My core is .NET and SQL. Not just writing queries, but understanding why things break when data grows, and fixing it without turning everything upside down. What I work with: • C# / .NET — data processing, automation, background services, desktop tools • SQL (deep) — complex queries, performance tuning, execution plans, large datasets • APIs & backend — REST, Node.js, Linux deployments • Automation — Selenium, scraping, data pipelines, legacy integrations • Infrastructure — Docker, Linux, FastAPI, PostgREST, full stack setup • Frontend — AG Grid, WordPress customization I also use AI in real work — tools like Claude and AI agents help me move faster, understand unfamiliar stacks, and scale solutions without slowing down. So if your project runs on something new — that’s not a blocker. I’ve worked with old and undocumented systems too — where you don’t have docs, only behavior. If you already tried the obvious fixes and they didn’t work — that’s usually when I get involved. I don’t need long explanations. I read the system, find the real issue, and fix that. I won’t promise miracles. But I will tell you exactly what’s wrong and what it takes to fix it.
