Technical ownership
for complex software.
Entwicklerherz strengthens existing project teams with senior software architecture and hands-on engineering – or owns clearly bounded extensions and integrations as a delivered outcome.
Senior software architecture and hands-on engineering – inside your team or as a bounded, owned delivery.
AI agents increase analytical and delivery capacity. Architecture, review, and approval remain in experienced hands.

// agent-assisted delivery
More delivery capacity – without automating responsibility.
Entwicklerherz orchestrates specialized AI agents for code analysis, implementation, tests, and documentation. The agents operate within a clear technical frame; an experienced software architect holds context, decisions, and outcome together.
AI agents handle code analysis, implementation, tests, and documentation – within a clear technical frame.
You are not hiring an autonomous bot team. You work with one accountable senior engineer whose delivery capacity is extended by agents.

Active in-house products
Products under our own responsibility.
Fachzirkel, SchemaCommunity, and openworkid are conceived, built, and operated by Entwicklerherz. Unlike the Lab tools, they are not experiments but publicly usable products.
Fachzirkel
LiveVerified professional platform for health practitioners with matching, marketplace, specialist groups, directories, and direct messaging.
Demonstrates role and verification workflows, moderation, search, messaging, passkeys, billing, and privacy-aware account lifecycles.

Do not just talk about AI engineering. Build tools for it.
The Lab creates engineering tools with a clearly stated maturity level. Changeproof is a working prototype tested against real codebases – not yet an independent product.
Visit Entwicklerherz LabChangeproof
Every merge with a verifiable record.
The Changeproof CLI analyzes a Git diff together with a ticket or specification. It creates a local Change Passport that maps requirements to changed files and tests, exposes open risks, and adds a verifiable integrity hash.
Reviewers get one artifact showing what was intended, what changed, which evidence exists, and what remains open before approval.
- Analyze ticket + Git diff
- Map tests + risks
- Create passport locally

Thinking from practice
August 20268 min
The requirement was unclear. The code is done anyway.
Coding agents don't eliminate unclear requirements. They eliminate the friction that used to make ambiguity visible.

Reviewing AI Code Is a Different Job.
AI code looks clean. But whether it fits the system can't be seen in the diff — only when you know what to check against.

Responsibility doesn't scale
Output can be parallelized, understanding can't. Why organizations are quietly converting responsibility into risk right now — and why it only surfaces when something breaks.

Let us clarify the right scope.
A short description of the system, bottleneck, and desired outcome is enough for an initial assessment.
