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...

I need a cloud-ready School ERP written in ASP.NET MVC (C#) that can host several schools under the same deployment while keeping data strictly isolated per client.

I need a small, self-hosted web application for a class project that lets students browse internship openings while giving companies and admins the tools they need to keep those listings current. The stack must stay within HTML, Java, PHP and MySQL so that I can run everything locally on my laptop (XAMPP/WAMP is fine).

I need a complete takeaway POS that installs and runs smoothly on any current Windows machine. The core workflow must cover the full service loop—order processing at the counter or over the phone, real-time inventory management that updates with every ticket, and seamless payment integration for cards, cash, and modern wallets.

I need two tightly-connected newsroom tools built as installable modules that can drop into a modern CMS (WordPress, Joomla, or Drupal—whichever you feel most confident customising). 1) Editorial Calendar & Planning The calendar must let editors line-up stories by date, assign them to reporters, and keep everyone talking in one place. At minimum it has to cover: • Content scheduling with a clear visual timeline • Task assignment that tracks status from pitch to publish • Lightweight collaboration/chat inside each story card 2) Reporter KPI Scoring Each published piece should automatically flow into a scoring engine that credits the reporter on: • Article reach • Publishing frequency • Reader engagement On top of those raw count...

I’m building a subscription-based service that lets customers reserve time slots through a mobile app and a companion website. The project covers three platforms from day one—iOS, Android and a fully responsive web interface—so a shared codebase or closely aligned stacks will keep maintenance sensible. Core functionality is already defined: users create and manage their own accounts, choose a plan, pay securely, and see an always-up-to-date booking calendar before confirming their reservation. Recurring payments, free-trial logic and prorated upgrades or downgrades all have to flow smoothly through the same checkout. Beyond that I’m flexible about the underlying tech; what matters is a clean, well-documented architecture that can scale as the subscriber base grows....

I’m kicking off a brand-new mobile product and will rely on you to architect both the Flutter front end and the Laravel back end from the ground up. The first release targets Android only, so performance, clean UI, and rock-solid API design are paramount. Please structure the code with future iOS and web expansion in mind. Clear, near-native English (C1 or better) is essential because we will review requirements, pull-requests, and sprint retrospectives and also communication with client (US) entirely in English. We’ll collaborate on an hourly basis; the current plan sits in the low-teens USD range, so think steady, agile progress rather than a rush job. Deliverables for our initial phase: • Laravel REST API with authentication, CRUD endpoints, and scalable database sche...
