I'm an intern hired as a generic "logistics solution" with data science and developer background at a large industrial company.Today I presented a project I built: a full-stack solution with frontend, backend, data, and AI components (Because that's what they have always looking for and I brought my expertise to tackle this) The repo is done, the license is done, and auth is compliant with company policies. The response was that if I leave, nobody can maintain it because there are 0 developers in the branch I work like 0 out of 1000 that actually work for this company, nobody knows how to code except subcontracted companies that develop another solutions by they are so useless and very bad maintained...

I'm not planning to stay long-term, and I'd like to be paid properly for the value I've created rather than leave it as a free handover or dump it.…
