Can a project started by another developer be taken over? — answered by Engineer Saeed Baatiah
Yes, and it is common. It starts with a short assessment inspecting what actually exists — the code, the database, the hosting, and documentation if any — and ends with a candid report: build on what is there or rebuild, why, and at what cost for each option. The only requirement to begin is full access. Assessing before pricing protects both sides from surprises that cannot be estimated from the outside.
