    Company is planning to implement ERPNext and now need it molded to my exact processes across the Finance, Inventory Management and CRM modules. The objective is to re-configure screens, forms and logic so day-to-day work flows naturally for both Admin and regular Employee users, each with the right permissions and an intuitive UI. What I expect from you: tailor the existing doctypes or build new ones, create the necessary scripts inside the Frappe framework, and adjust role-based permissions so that admins have full control while employees see only what they need. Any new fields, server scripts, print formats or integrations you propose should stay fully upgrade-safe and documented. You’ll get direct access to a staging server, and I’ll provide a detailed workflow map upon ki...

    I’m assembling a reliable database of Mumbai-based borrowers who already have an active home loan and I’m paying ₹10 per complete record. Each record must contain: borrower’s name, mobile number, pincode, total amount sanctioned, current outstanding balance, interest rate, EMI, and remaining tenure. I’ll start by reviewing a sample of 10 fully populated records delivered in an Excel spreadsheet; once the format and data quality are approved I’ll commission larger batches. Feel free to tap verified channels such as financial institutions, real estate databases, and credit-bureau sources like CIBIL. I expect intermediate validation—so be sure every field follows a consistent format (numbers in the same units, phone numbers in the same pattern, etc.) be...

    I need a full-featured, small-scale multi-vendor marketplace built natively for both Android and iOS.

User roles the system must recognise: - Buyers - Sellers/Vendors - Admin Core flows include simple account creation, product upload with images and variants, cart and checkout, order tracking, and in-app messaging between buyer and vendor. I will also need an admin console (web or app-based) where I can approve vendors, moderate listings, manage commissions, and view analytics.

    I have several production PL SQL scripts that are starting to show their age: execution times have crept up and they are consuming more CPU and memory than I am comfortable with. The primary focus of this project is therefore PLSQL itself, not application-level logic or UI work. What I need from you is a careful optimisation of the existing codebase. The goal is two-fold—raise overall performance and cut back on resource usage—without changing the functional output in any way. You will be working with code that is already in use, so a light-touch, incremental approach that can be verified against current results is essential. Deliverables I expect • Revised PL SQL scripts ready for drop-in replacement • A short before/after performance summary (timings and resourc...

    I am looking to have a self-contained desktop application built that lets us record and track three key data sets in one place: staff information, individual training records, and detailed instrument-calibration histories. The program will be used on a small internal network, so a local database engine such as SQLite, MS Access, or an embedded PostgreSQL instance is perfectly acceptable as long as installation remains straightforward for non-technical users. Two role levels must be enforced: Admins need full create / update / delete privileges plus the ability to add new users, import legacy spreadsheets, and run global reports, while Managers only require read-only dashboards and the ability to print or export filtered reports for their teams. Typical daily tasks should feel intuitive: ...

Clinicians must be able to type directly into clean, well-labelled forms, import legacy records from CSV or Excel, and drop scanned documents that the system will pass through OCR, automatically mapping recognised values to the correct fields. • On-the-fly calculations.
