Personal AI Engineering Project — Croky AI at Crocky AI
Product:
- Built a production-ready AI platform for generating brand-aware marketing images and videos from product data, user requirements, and uploaded media.
- Own the platform architecture, technical roadmap, API design, security, deployment workflow, operational reliability, and model-provider strategy.
- Developed the core platform in .NET and built supporting AI and workflow prototypes in Python, applying language-independent API contracts and structured interfaces between services and model providers.
- Implemented reliable background processing with RabbitMQ, persisted workflow state, idempotent handling, retries, failure recovery, logging, secure storage, authorization, and credit accounting.
- Made pragmatic build-versus-buy and model-routing decisions based on reliability, latency, cost, and maintainability rather than novelty.
Agent Orchestration & RAG Systems
- Built and compared agent workflows using Microsoft Agent Framework, LangGraph, and LangChain, including tool use, conditional routing, clarification steps, state management, and hand-offs between agents.
- Implemented reusable .NET components for agents, prompts, tools, model providers, structured responses, and retrieval with pyvector, making it easier to change AI providers without rewriting the core workflow.

About the technology
What ASP.NET covers
ASP.NET is Microsoft’s web framework for building server-side applications on the .NET stack. It is used for public websites, business portals, APIs, and internal tools that need structured data handling and secure access.
Common project work
- Build or extend ASP.NET MVC and ASP.NET Core applications
- Create Web API services for web and mobile clients
- Maintain Web Forms, authentication, and role-based access
- Connect SQL Server, Azure services, and external systems
- Improve performance, deployment, and error handling
Ecosystem and tools
Strong professionals work comfortably with C#, .NET, Visual Studio, IIS, Entity Framework, and Azure. They also understand dependency injection, logging, configuration, and testing so projects stay maintainable after launch.
When companies bring in freelancers
Companies usually need freelance support when a team must modernize an older codebase, deliver a new API layer, or clear a backlog in an active product. ASP.NET specialists are also useful for migrations from Web Forms to ASP.NET Core or for short-term help during release work.
What strong specialists do well
A good ASP.NET professional writes clear server-side code, keeps controllers and services separated, and handles security with care. They know how to trace bugs in production, improve response times, and avoid changes that make later maintenance harder.
Fit for existing systems
ASP.NET often sits inside larger Microsoft environments with SQL Server, Azure, Active Directory, and Outlook or SharePoint integrations. That makes it a practical choice for companies that need stable business software and want specialists who can work with established patterns, not rewrite everything from scratch.
Frequently asked questions
What clients ask us most about ASP.NET — answered in short.
ASP.NET is used to build web applications, APIs, dashboards, and internal business systems on the Microsoft stack. It is a common choice when the project needs secure authentication, structured data access, and close integration with C# and SQL Server.
ASP.NET usually refers to both the classic framework and the newer ASP.NET Core family, so the right choice depends on the codebase and target environment. For new work, ASP.NET Core is often the better fit because it is the current path for modern .NET applications, while older systems may still need classic ASP.NET support.
A strong ASP.NET specialist should also know C#, LINQ, Entity Framework, SQL Server, and basic cloud work in Azure. For many projects, skills in JavaScript, HTML, CSS, authentication, and API design matter just as much as the framework itself.
A good ASP.NET freelancer can help even if the brief is not perfect, but they still need the business goal, the current stack, and the main pain points. The clearer the requirements are around integrations, authentication, and deployment, the faster the right specialist can make progress.
ASP.NET is often chosen when a company wants tight integration with Microsoft tools, strong typing, and a mature enterprise stack. Compared with PHP or Node.js, it is usually a better fit for teams already invested in C# and Azure; compared with Java frameworks, it often appeals to organizations that want the Microsoft ecosystem end to end.
Most ASP.NET work can be done remotely because it centers on code, reviews, and deployment pipelines. On-site time only becomes important when the team needs close coordination with a legacy system, sensitive infrastructure, or stakeholders who prefer direct workshops.
A strong ASP.NET professional can explain trade-offs clearly, show relevant shipped work, and describe how they handle testing, performance, and security. Look for clean code structure, practical experience with the exact version in use, and evidence that they can work inside an existing codebase without creating more technical debt.
ASP.NET is common in organizations with Microsoft-centered operations, such as finance, logistics, healthcare, public sector, and internal corporate software teams. These companies often need specialists for maintenance, modernization, or new features that must fit into an established environment.
The average hourly rate of freelancers who have used ASP.NET in their recent projects is 90 €, which corresponds to a daily rate of about 722 € based on an 8-hour working day.
Of the freelancers who have used ASP.NET in their recent projects, 82% hold at least a Bachelor's degree, 47% hold at least a Master's degree, and 4% hold a doctorate.
On average, freelancers who have used ASP.NET in their recent projects have 21 years of professional experience, with a single engagement typically lasting around 2.2 years.
The most common languages among freelancers who have used ASP.NET in their recent projects are German (99%), English (94%), and Russian (15%).
The most common industries among freelancers who have used ASP.NET in their recent projects are Information Technology (95%), Manufacturing (56%), and Banking and Finance (51%).
The most common business areas among freelancers who have used ASP.NET in their recent projects are Information Technology (99%), Product Development (96%), and Project Management (59%).
