Darkhan B.

Hi, I'm a software engineer with 10 years of experience building and maintaining real-world applications. My main background is in C#, .NET, Microsoft Azure, and full-stack development, and more recently I've been working with Generative AI, LLMs, RAG, and AI integrations to bring practical AI features into existing products. I’m comfortable working across the stack — from backend APIs, databases, and cloud services to React frontends and system architecture. I can join an existing codebase, understand how the pieces fit together, troubleshoot difficult problems, or build a new application from the ground up. 🤖 AI & LLM Integration I work with AI as part of real applications rather than as a standalone experiment. I can help you: - Integrate LLMs and Generative AI into existing .NET or web applications - Build RAG (Retrieval-Augmented Generation) solutions using your own data - Develop AI-powered features, assistants, and chatbots - Connect AI services with internal systems, databases, and third-party APIs - Design the backend and API layer needed to make AI features reliable and maintainable My focus is on finding where AI actually adds value to a product and integrating it cleanly with the rest of the system. 💻 Full-Stack Development My core development stack includes: - C# / .NET / ASP.NET Core - React / TypeScript - RESTful APIs & API Integration - Entity Framework / EF Core - SQL & NoSQL databases - Node.js - Third-party API integrations I'm especially comfortable with projects where frontend development, backend services, APIs, databases, and cloud infrastructure need to work together. ☁️ Microsoft Azure Azure has been a major part of my work over the years. My experience includes: - Azure Functions - Azure Service Bus - Azure Storage — Queue, Table, and Blob - Azure SQL Database - Azure Active Directory / App Registration - Azure Application Insights - Azure DevOps I've also worked extensively with event-driven systems, asynchronous processing, and messaging, including applications where multiple services need to communicate reliably. 🏗️ Architecture & Maintainable Software I care about architecture, but I also believe architecture should serve the project — not make it unnecessarily complicated. I've worked with: - Clean Architecture - Domain-Driven Design (DDD) - Modular Monoliths - Event-Driven Architecture - Messaging and integration patterns Sometimes a sophisticated architecture is justified. Sometimes a straightforward solution is better. My goal is to build software that works well today while remaining understandable, testable, and maintainable as the product grows. 👋 How I Work I enjoy solving problems, especially when the answer isn't immediately obvious. I also contribute to open-source projects and maintain my own GitHub repositories where I experiment with new technologies and ideas. When working with clients, I prefer straightforward communication. If I see a potential problem, I'll point it out. If there's a simpler approach, I'll suggest it. And if I don't know something, I'll say so and investigate it rather than pretend otherwise. If you're building an AI-powered application, need LLM or RAG integration, have a .NET/Azure system, or need an experienced full-stack developer to help improve an existing product, feel free to send me a message. I'm happy to start with a conversation about your project and see whether I'm the right fit.
