Journey 3 · Existing system → new features
New features are needed, but every change in a tangled codebase is a risk.
New features in existing systems.
DevCurrent maps your code and the impact of the change first, then builds, reviews and tests the feature safely.
Read the text in the film
- Brownfield intelligence. Understanding software that already exists — well enough to change it safely.
- Most real engineering is brownfield — changing software that already exists, spread across many repositories.
- Cross-repo federation — many repos are read as one connected system.
- A structured model is assembled — entities, public interfaces, integration seams.
- A dependency graph across architectural layers — including the system's own blind spots, with a confidence score.
- Impact mapping — the blast radius of a change is mapped before a single line is touched.
For you if you're saying
The system is business-critical, and the people who knew the code have left.
Every change takes ages, because nobody dares touch the code without understanding it first.
We have a long list of requests waiting for capacity.
How it runs
One platform for the whole team: product owners, architects, developers, testers and security leads work in the same journey, each at their own gate.
- Your repository is connected and mapped: its parts, interfaces, data, dependencies and business rules, each cited to the code.
- You describe the change.
- DevCurrent makes an impact map: what the change touches, and how far it reaches.
- The repository's owner confirms the map.
- The feature is built, reviewed and tested, and delivered as a pull request.
What you get
The new feature as a reviewed, tested pull request in your repository, with the impact map behind it.
Faster
The understanding that takes so long to build up by hand is ready before the work starts.
Better
The change lands where the map says, and is tested before it reaches you.
Cheaper
Less time digging through old code, and fewer defects in production.
Where you decide: the repository's owner confirms the impact map, and a second person approves before the change goes live.
Fully autonomous or fully gated →Other journeys
DevCurrent understands the old system, decides with you what to carry, redesign or drop, rebuilds it on a modern stack, and proves it still behaves the same. See the journey → Specification to production The specification is signed off, but building it still needs a team and months you don't have.
The full pipeline — architecture, data, backend, frontend, tests, security review and deployment — with your approval at every gate. See the journey → Existing code to audit report No one knows what is really in the code: the risks, the weak spots, the untested parts.
A full security, architecture and test-coverage audit, with the fixes and the missing tests ready to apply. See the journey →
