I need a lightweight, browser-accessible librarian system that stores all of our operational procedure documents in one place and makes them instantly findable. The core requirement is a fast, intuitive search-and-filter experience: users must be able to type keywords or apply simple filters (e.g., department, date, tag) and see matching SOPs in seconds. Because the whole team will reach the library through a standard web interface, the front-end needs to be responsive and straightforward—think clean tables or card layouts, file preview where feasible, and clear download links. I’m flexible on the back-end stack (PHP/Laravel, Node/Express, Python/Django, etc.) as long as it’s secure, well-documented, and easy for another developer to pick up later. A lightweight database such as MySQL, PostgreSQL, or even SQLite is fine; whichever you choose, please index it properly so search remains snappy as the library grows. We’re not implementing full version control or granular permission tiers for this phase; however, structuring the code so those features could be added later would be appreciated. Basic admin authentication, simple upload forms, and an option to tag or categorise each SOP on upload will do the trick for now. Deliverables: • Deployed web application (or clear deployment script) with working search & filter • Source code repository with concise README • One-page user guide covering upload, tagging, and document retrieval If you have prior examples of similar document repositories or strong ideas on improving search speed and relevance, feel free to mention them when you apply.
