I’m putting together a simple, learning-oriented e-commerce web application in Java and would like clean, well-commented code that I can study and extend later. The core flow is straightforward: a visitor lands on the site as a Guest, registers or logs in to become a Customer, browses a product catalogue, adds items to a cart, and submits an order—no payment gateway needed. Role management must cover Admin, Customer, and Guest. From the Admin dashboard I need the ability to Add, Edit, and Delete products, view every order that comes through, and manage the user list. For data storage we’ll use MySQL; please include a schema script plus any sample seed data so the app is ready to run after import. I’m comfortable running the project with Maven or Gradle, so structu...

I have a green-field web idea and want it built from scratch on a Python stack—Django is my first choice, though a solid case for Flask is welcome. The project covers everything from planning the architecture and database schema, through building the API and responsive front-end, to deploying a production-ready version on a cloud host. Clean, well-documented code in a Git repository, regular checkpoints, and clear communication are non-negotiable. If you have shipped live Django or Flask sites before, I would like to see them and hear how quickly you could deliver an MVP. Deliverables • Technical design and schema draft • Working MVP on a staging server • Production deployment with hand-over notes I’m ready to start as soon as I find the right fit.

We need a skilled WordPress developer to build a custom CRM system with eCommerce functionality that supports multiple user roles and access levels.

Requirements: • Strong WordPress development experience • WooCommerce integration and customization • Custom user role and permission management • Order tracking system implementation • Customer dashboard development • Experience with AI-assisted development tools (Claude preferred) • Frontend development skills (HTML, CSS, JavaScript) • Database des...

I’m putting together a full-stack web application for advertising residential properties and I’d like a React front-end paired with a Node.js (Express) back-end. The platform is residential-only, so every screen, filter and data model can focus on homes and apartments rather than commercial space. Core data visible to visitors must include the number of bedrooms, total square footage and the asking price; those three fields need to be prominent in both card and detail views. Search and sorting should work off the same attributes. Role-based access is essential: • Admin – complete control over users, listings and site settings. • Agent – create, edit and deactivate their own listings, upload photos, mark properties as sold. • Buyer – brow...

The goal is to create software that matches the exact flow of my dealership operation instead of forcing us to adapt to an off-the-shelf package.

I’m ready to launch a fantasy sports platform that mirrors Dream11 in both look and feel. I need the complete, production-ready Android source code plus deployment on my own hosting server, so the app is live and fully functional when you hand it over. Core functionality must include secure user authentication, real-time scores and match updates, and support for multiple sports right out of the gate. I want the UI to track closely with Dream11’s visual language—fonts, color palette, screen flow—so users feel instantly familiar while still keeping the branding elements I’ll provide. Beyond basic ads, I’ll rely on two monetisation streams: subscription tiers and sponsored content slots. Please wire these into the codebase so I can configure pricing and s...

Looking for SQL expert who has experience with the stored procedures to debug and fix the errors

Thousands of lines of T-SQL that once worked are now returning incorrect results. I need a fresh set of expert eyes to comb through the entire script, pinpoint exactly where the logic breaks down, and fix it. The code lives in SQL Server. While you work through the main script, I also need you to cascade several hundred new parameters into a series of dependent stored procedures. These procedures already compile; they simply require the additional parameters to be wired through correctly so downstream calculations stay consistent. What I expect from you: • A clean, corrected version of the original query and any touched procedures • A concise change log explaining the root cause of the logical error and how you resolved it • Updated stored procedures with the new param...

I have been running my numbers in spreadsheets for far too long and now need a properly structured Microsoft Access solution. The goal is to design and optimise a database whose sole focus is managing financial data—specifically our invoices and billing records. Here is what I need from you: • A relational schema that keeps the tables normalised, eliminates duplicate data, and supports growth. • Intuitive forms for entering new invoices, applying payments, and updating client details without exposing raw tables. • Parameter-driven queries and summary reports that let me filter by client, date range, paid / outstanding status, and export cleanly to Excel or PDF. • Thoughtful use of indexes, validation rules, and VBA where necessary so the system stays fast ...

I’m ready to launch a brand-new corporate website and need an experienced PHP developer who can take the project from concept to production. The build will start on a clean slate, so you’ll be free to lay down a solid architecture that supports modern design enhancements, feature-rich modules, and smooth, high-performance operation right out of the gate. What matters most is a polished, responsive interface that matches our brand, backed by clean, well-documented PHP code (Laravel, Symfony, or a comparable framework is welcome). Alongside the usual pages—company profile, services, team bios, contact—you’ll weave in easy-to-use content management so our staff can update copy and images without touching code. From the beginning, please bake in performance best ...

I’m building a full-scale, multi-tenant SaaS platform and need an experienced developer who can take the idea from architecture through deployment. The core requirement is true multi-tenancy: a single code-base and shared infrastructure that isolates data and configuration for each customer while still letting me roll out updates globally. Access control must combine both role-based and feature-based permissions so that I can define granular user roles inside each tenant and also toggle modules or premium features per account without redeploying. I want the data layer designed around a hybrid model—relational tables for structured, transactional data alongside a NoSQL store for high-volume or schemaless collections—so familiarity with both SQL (PostgreSQL or MySQL) and s...

I need a straightforward mobile app that runs smoothly on both iOS and Android. Its core job is to let me record every ice sale in seconds: • I select (or add) a customer and their pre-saved price per 1 kg, 3 kg, and 5 kg bag auto-fills. • I type the quantities sold and the app instantly shows the line total and the grand total. • At any moment I can open a dashboard that sums all sales: one view groups them by day, another rolls them up by calendar month. A small back-office screen must let me: – create, edit, or deactivate customers and their individual price lists; – correct any mistaken sale; – back up or export the raw table (CSV or similar). I’m open to your suggestion on the underlying data store—MySQL, SQLite, Firebase, or a...
