Fred Hauschel
Last position:
Software Architect and Developer at Personal project
A recurring problem in my own AI-supported projects: requirements analysis, use cases, and architecture decisions can be created quickly with AI support, but they remain hard to trace and scattered across Markdown files – knowledge is lost as soon as it is no longer in the context window. arknet turns requirements engineering and architecture knowledge into structured, verifiable data instead of plain text: requirements, use cases, and architecture decisions as a continuously linked knowledge graph, traceable from the requirement to the architecture decision – queryable for both people and AI agents alike. Technically based on RDF/OWL and its own MCP server.
Result: MCP daemon running, Docker image automatically published on GHCR, nine hexagonal modules, eleven ADRs (including an open-core licensing model). Requirements engineering and ubiquitous language hexagon active. Publicly available since 07/2026 as a Community Edition under Apache-2.0 (github.com/kogn-io/arknet), together with the Claude Code plugin and the GHCR image; open-core model.
Label: Java, Maven, RDF, RDF4J, OWL, SPARQL, Model Context Protocol, Spring AI, Docker, GitHub, Git, Claude Code, Obsidian, DDD, Hexagonal Architecture, ArchUnit, JUnit, AssertJ

Robin Walter Scherler
Last position:
Developer at agentic-engineer.online
agentic-engineer.online is my publicly testable live demo and at the same time the platform where I show my work. Originally created as a recruitment trial task, I have since continued to run it as my own demo, learning, and product project — on a Hetzner VPS behind a Cloudflare tunnel, through a multi-stage AI-orchestrated deploy pipeline with snapshot rollback. If a deploy step breaks, the system falls back to the last clean snapshot, the script is adjusted, the test repeated — empirical, test-driven, without hand tuning.
- Technically behind it: Python and FastAPI, an OpenRouter model cascade, SQLite persistence, and Cloudflare edge tuning.
- I am the developer and the strictest customer of my own AI work in one person — what started as a prototype has become a tool I use every day and against which I test my own products.

About the technology
HTTP basics
HTTP, or Hypertext Transfer Protocol, is the standard way clients and servers exchange web content. It carries pages, API calls, images, forms, and many app-to-app requests. Strong experts know how methods, headers, status codes, and caches shape each request.
Where it is used
- Public websites and web apps
- REST APIs and partner integrations
- Reverse proxies, gateways, and load balancers
- Mobile and browser communication
- Internal services that expose endpoints
HTTP sits under most modern internet traffic, even when the app layer looks simple. Companies bring in specialists when request handling, caching, redirects, or auth flows need to be clean and predictable.
Ecosystem and versions
Work often touches HTTP/1.1, HTTP/2, and HTTP/3, plus tools like curl, browser dev tools, Postman, nginx, Apache httpd, and proxy layers. Good professionals understand TLS, keep-alive behavior, compression, content negotiation, and how an API contract behaves across clients.
When to hire
Bring in freelance expertise when APIs fail in production, client requests are slow, or a migration changes how traffic is routed. German teams often use remote specialists for distributed product work, while on-site support helps when there are legacy systems, network constraints, or tight coordination with operations.
What strong professionals do
A strong HTTP specialist reads logs, follows a request end to end, and spots the real cause instead of guessing. They can separate browser issues from server issues, verify headers and caching rules, and explain trade-offs in plain language. They also work well with backend, frontend, and infrastructure teams.
Common project outcomes
- Clear API behavior and consistent responses
- Better caching and faster page delivery
- Cleaner redirects and auth handling
- Safer proxy and gateway configuration
- Fewer client-side and server-side surprises
Frequently asked questions
Not sure where to start with HTTP? These answers cover the essentials.
A strong HTTP specialist helps with the way web clients and servers talk to each other. That includes request methods, headers, cookies, status codes, redirects, caching, and API behavior. Companies usually bring in this expertise when traffic is hard to debug or when responses are inconsistent across browsers and services.
No. HTTP is the transport and message protocol; REST is an architectural style that often runs on top of it. A freelancer who knows HTTP well can still work on REST APIs, but they should also understand how clients, proxies, and caches affect the traffic.
HTTP is the default choice for web pages, browser-driven apps, and many public APIs. WebSocket is better for persistent two-way messaging, while gRPC fits strongly typed service calls between systems. A good specialist can explain when HTTP is still the simplest and safest option.
The most useful companion skills are TLS, browser debugging, API design, caching, reverse proxies, and server configuration. A HTTP professional should also be comfortable reading logs and understanding how frontend and backend behavior affect each other. In Germany, clear written communication in English is often important for cross-team work.
A small cleanup around headers or redirects may need only focused help, while a production incident or migration needs someone who has seen complex traffic patterns before. With HTTP, depth matters more than a title. Look for professionals who can explain root causes, not just settings.
Most HTTP work can be done remotely because the evidence lives in requests, logs, and configs. On-site can help when a project includes legacy infrastructure, network appliances, or close coordination with operations and product teams. In Germany, many teams use a mix of both depending on the phase of the work.
Ask for concrete examples of debugging request flow, caching, or proxy issues. A solid HTTP specialist can describe the problem, the checks they ran, and the fix in clear steps. Quality shows up in precise answers, clean change plans, and an ability to think from the client request all the way to the server response.
They usually want to know which systems are involved, whether the issue is a one-time fix or ongoing support, and how much access they will have to logs and test environments. For HTTP projects, it also helps to know which clients matter most, such as browsers, mobile apps, or external APIs. Clear scope and response ownership make the work much smoother.
The average hourly rate of freelancers in Germany who have used HTTP in their recent projects is 92 €, which corresponds to a daily rate of about 735 € based on an 8-hour working day.
