For Barcelona startups with code inherited from a vendor who stopped responding, we audit the app's real state before accepting the easy diagnosis of rebuilding everything. We refactor what is reusable, modernize abandoned libraries and leave the app documented, so your team regains real technical control without losing months on a full rewrite that is not always necessary.
Did Your Previous Developer Leave Your App Outdated? We Rescue It in Barcelona
In Barcelona we frequently see the same pattern: a startup that grew fast on top of an app built by a vendor no longer available, with code nobody on the current team fully understands. We first audit what can be rescued before recommending a rebuild, refactor in verifiable stages while keeping the app running, and document everything so your technical team regains real autonomy over the project.
We help you regain control of repositories, developer accounts and credentials that got scattered.
We analyze the legacy code and deliver an honest diagnosis of what to rescue and what not.
We define the order of work: first what unblocks publishing updates, then deeper modernization.
We execute the modernization in stages, keeping the app operational throughout the whole process.
We validate that everything that worked before still works after each stage of the migration.
We close with the updated app, complete documentation and, if you want, an ongoing maintenance plan.
We understand the pressure of a startup that needs to keep shipping features while carrying a legacy app nobody on the current team built. We audit the real code to separate what is rescuable from what should be rewritten, always prioritizing keeping the app running in production as we work, without the risk of a full migration that halts your product during critical weeks.
We document everything that was missing: architecture, technical decisions and deployment processes, so your internal team gains real autonomy over the project. In an ecosystem where talent moves fast between companies, that documentation is what prevents your startup from getting trapped again depending on a single person who knows the code and could leave for another opportunity at any time.
We assess the real state of the code, its dependencies and its risks, with a clear report of what to rescue and what to rewrite.
We modernize old native code into the current languages Google and Apple recommend, incrementally and without stopping the app.
We bring outdated framework versions up to date, resolving the breaking changes accumulated between versions.
We identify unmaintained dependencies and migrate them to active alternatives before they become a security risk.
We adjust the app to the API levels and current policies of Google Play and App Store so it can publish updates again without friction.
We document the code, architecture and deployment processes, the insurance against getting trapped with a single vendor again.
