I design and implement future-proof APIs and integration layers for products, platforms, and enterprise systems. The focus is not only on endpoints, but on the full API lifecycle: design-first specifications, robust implementation, high-quality documentation, secure runtime management, and the governance needed to keep APIs consistent and operable over time.
What Friedrichs IT delivers
Production-ready API engineering across design, implementation, documentation, and governance — designed to create interfaces that are usable, secure, and sustainable over the full lifecycle.
API Design & Lifecycle
I design APIs with an API-first approach, supported by clear contracts, versioning strategies, and lifecycle thinking from the start. This includes OpenAPI and AsyncAPI specifications, consistent resource modeling, and pragmatic standards that help teams design interfaces that remain usable as products and platforms evolve.
API Implementation
I implement reliable APIs, integrations, and service interfaces across backend systems and distributed architectures. The goal is production-ready API layers with strong contracts, pragmatic delivery patterns, and clean implementation boundaries — including contract-driven development, integration logic, and reusable client or SDK generation where it adds value.
Documentation & Developer Portals
High-quality API adoption depends on clear and usable documentation. I build developer portals, interactive API references, integration guides, examples, and try-out experiences that help internal and external consumers understand, test, and adopt APIs faster.
Security, Gateways & Governance
I help secure and govern APIs across their runtime and lifecycle with the right mix of authentication, gateway capabilities, and organizational standards. This includes OAuth 2.0, policy enforcement, API gateways, and governance practices that improve consistency, reduce risk, and keep API ecosystems manageable as they grow.
How I can help
- Design API-first interfaces with clear contracts and lifecycle thinking.
- Build reliable APIs and integration layers for real production use.
- Improve adoption with strong documentation and developer portals.
- Secure and govern growing API landscapes with gateways and policies.
