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 role
What they build
.NET Developers design and ship business software in C# and the wider .NET stack. They build APIs, web apps, backend services, integrations, and internal tools that have to be stable, maintainable, and easy to extend.
- ASP.NET Core web applications and REST APIs
- Background services, worker processes, and message-driven components
- Integrations with ERP, CRM, payment, identity, and data platforms
- Refactoring, bug fixes, and performance improvements
Core skills
Strong .NET Developers understand object-oriented design, dependency injection, testing, and clean architecture. They write readable code, handle edge cases, and work well with product teams, QA, and operations.
Typical skills include C#, ASP.NET Core, Entity Framework Core, SQL Server, LINQ, REST, JWT, and Git. Many also know Azure, Docker, and message brokers such as RabbitMQ or Azure Service Bus.
Where they fit
Companies bring in freelance .NET Developers when a product team needs extra delivery capacity, a legacy system needs modernization, or a new service must be built without adding permanent headcount. They are also useful for short, focused assignments such as API design, migration work, or release support.
In Germany, they often support software teams in industry, manufacturing, logistics, finance, insurance, and B2B SaaS. On-site work can help when stakeholders are local and requirements change quickly, while remote collaboration works well for development, code reviews, and handover.
What good looks like
A strong .NET Developer does more than write code. They ask the right questions, document important decisions, and keep the codebase easy for the next engineer to maintain.
- Delivers working software that fits existing architecture
- Writes tests and handles deployment concerns early
- Communicates clearly about trade-offs and risks
- Spots weak points in performance, security, or data handling
Typical specialisms
Many projects need a specific kind of .NET expertise. Some freelancers focus on backend development and APIs. Others are stronger in enterprise applications, cloud migration, or maintenance of older .NET Framework systems that still support critical business processes.
The right profile depends on your stack. A C# developer with ASP.NET Core experience may be ideal for a new product, while a software engineer with deep integration and database skills is better for complex enterprise environments.
Why companies hire freelance
Freelance .NET Developers make sense when time matters or the need is temporary. They can step into an existing team, take ownership of a clear work package, and deliver without a long hiring process.
This is especially useful for release peaks, migration projects, urgent bug fixing, proof-of-concept work, and team gaps after internal staff move on. The best freelancers adapt quickly to your coding standards, ticket process, and review flow without slowing the team down.
Frequently asked questions
Need clarity? These are the questions we hear most often about .NET Developers.
A .NET Developer builds or improves software in the .NET ecosystem, usually with C# and ASP.NET Core. That can include APIs, web apps, backend services, integrations, database work, and bug fixing. In many projects, the work also covers testing, deployment support, and cleanup of legacy code.
Look for solid C#, ASP.NET Core, SQL, and Git skills first. Good candidates also understand testing, dependency injection, REST APIs, and how to work with cloud services such as Azure. If your system is older, experience with .NET Framework and migration work can matter just as much.
Not always, but the roles overlap a lot. A .NET Developer usually works in the Microsoft stack and often focuses on backend services, business applications, and integrations. A C# developer may be narrower in language focus, while a software engineer can be broader and cover more stacks or system design work.
A freelancer is a good fit when you have a defined scope, a deadline, or a temporary gap in the team. That includes migration projects, release support, feature spikes, or urgent maintenance work. If you need speed and flexibility more than long-term team growth, a freelancer is often the better choice.
Both models work well, depending on the project. A .NET Developer can usually handle development, reviews, and most coordination remotely if requirements are clear and the team works well with tickets and code reviews. On-site time can help when the project involves local stakeholders, workshop-heavy discovery, or sensitive handovers.
Expect working code, clear commits, and documentation for important decisions. A .NET Developer should also provide test coverage where it matters, help with deployment steps, and leave the system in a maintainable state. For larger projects, API contracts, migration plans, and handover notes are often part of the delivery.
Ask for examples of similar systems, not just a list of technologies. A strong .NET programmer can explain how they structured a solution, handled database access, tested critical paths, and reduced technical debt. Code review habits, communication style, and the ability to talk about trade-offs are strong quality signals.
In Germany, .NET Developers often support teams in manufacturing, logistics, finance, insurance, and B2B software. These companies usually need reliable backend systems, integrations, and tools that fit existing enterprise landscapes. The best freelancers can work with both technical teams and business stakeholders without losing detail.
The average hourly rate for .NET Developers in Germany is 90 €, which corresponds to a daily rate of about 720 € based on an 8-hour working day.
Of the freelancers working as .NET Developers in Germany, 95% hold at least a Bachelor's degree, 64% hold at least a Master's degree, and 5% hold a doctorate.
On average, freelancers working as .NET Developers in Germany have 19 years of professional experience, with a single engagement typically lasting around 2.2 years.
