Anthony M.
Last position:
Research and Development, AI for Enterprise at Mwanachama
- Built an MCP (Model Context Protocol) layer for Mwanachama's agency service, turning domain manager methods into callable AI-agent tools. This included a composite tool that builds a full organization design (org chart, goals, workflows, RACI matrix) from one specification.
- Built the chat-driven agency builder (Wakala Studio and API), where an organization describes its structure in natural language and an AI agent uses those tools to construct and modify the live design.
- Added an insights service so an organization can review AI-agent interactions and completed work. Insights from that review feed back into solution design, gated by architect and user sign-off.
- Alongside this, designed and built the platform itself: ~20 Go microservices on PostgreSQL, Flutter and React clients, deployed on Kubernetes.
- AI agents scan the platform autonomously for security gaps and run scripted tests, covering API (Postman-style) and UI testing. The rest of the work stays supervised. No rogue agents, promise.
- Building an AI-native enterprise platform that structures organizational data, workflows and responsibilities for both people and AI agents.
- Models accountability through RACI, allowing human and AI participants to take different operational roles, including Responsible, Accountable, Consulted and Informed. AI agents can also take controlled approval roles where the organization assigns that responsibility.
- Extended the organizational and operational-risk themes from my Executive MBA thesis into software, making roles, processes and controls explicit and machine-readable.
- Structures enterprise context so LLM interactions use more relevant information instead of repeatedly processing large amounts of unstructured content.

About the technology
C# at a glance
C# is a strongly typed, object-oriented language from Microsoft. It runs primarily on the .NET platform and supports web services, desktop software, cloud workloads, games and business applications. Its tooling combines language safety, modern syntax and a broad standard library.
What it builds
C# specialists deliver software across many business domains:
- ASP.NET Core websites, APIs and distributed services
- Enterprise systems for finance, manufacturing and logistics
- Windows applications with WPF or Windows Forms
- Interactive products and games with Unity
- Cloud-native workloads on Microsoft Azure
.NET ecosystem
The wider C# ecosystem includes .NET, ASP.NET Core, Entity Framework Core, LINQ and NuGet. Strong professionals also work with dependency injection, asynchronous programming, REST, messaging and authentication. They select libraries carefully and keep application boundaries clear.
When companies hire
Freelance expertise helps when an internal team needs to modernize a legacy .NET application, extend a product quickly or stabilize a critical service. Companies also bring in specialists for migrations, API design, test automation, performance reviews and cloud deployments. In Frankfurt, C# expertise is relevant to financial services, industrial businesses and software companies, with remote and on-site collaboration both common.
Skills that matter
A capable C# professional understands more than syntax. Look for practical experience with architecture, relational databases, SQL, testing, Git, CI/CD and observability. Experience with Azure, containers and event-driven systems is valuable when the application must scale across services or environments.
Quality signals
Strong specialists explain trade-offs instead of presenting one fixed solution. They write readable code, use automated tests and make failure handling explicit. Ask for examples of production systems, technical decisions and delivery outcomes. For remote work with a Frankfurt team, clear written communication, reliable planning and comfortable collaboration in English or German can matter as much as framework knowledge.
Frequently asked questions
Need clarity? These are the questions we hear most often about C#.
C# is used for web applications, APIs, enterprise software, desktop tools, cloud services and games made with Unity. It is especially common where teams want a mature language with strong tooling and close integration with Microsoft .NET.
C# and Java both support large, strongly typed applications and extensive server-side ecosystems. C# is closely integrated with .NET and Azure, while TypeScript is primarily used with JavaScript runtimes and browser applications; the right choice depends on the existing stack, team skills and delivery goals.
A strong C# freelancer often works with ASP.NET Core, Entity Framework Core, SQL, REST APIs, automated testing and Git-based delivery. For distributed systems, experience with Azure, containers, messaging, security and observability is also useful.
The required depth depends on the system rather than a job title or a fixed tenure. A small API may need solid ASP.NET Core and database skills, while a legacy migration or high-risk enterprise system calls for proven architecture, testing, troubleshooting and release experience.
Yes. C# projects are well suited to remote collaboration through repositories, issue tracking, automated builds and regular technical reviews. On-site workshops can still help with discovery or legacy systems, while English is common and German may be useful in local business settings.
Ask the C# specialist to explain a comparable system, key trade-offs and how quality was verified. Review testing habits, code clarity, API design, security awareness and their approach to diagnosing production problems rather than relying only on framework familiarity.
C# is well suited to cloud applications through .NET, ASP.NET Core and services such as Azure Functions and container hosting. A capable specialist should also understand stateless design, configuration, deployment automation, logging and resilient communication between services.
C# is the programming language, while .NET is the runtime, libraries and development ecosystem used to execute and support it. People sometimes say “.NET specialist” when they mean a C# professional, but a project may also require knowledge of other .NET languages, frameworks or platform services.
The average hourly rate of freelancers in Frankfurt, Germany who have used C# in their recent projects is 93 €, which corresponds to a daily rate of about 741 € based on an 8-hour working day.
