    I am putting together an internal business web application and I need an extra pair of hands who is comfortable living in the Python + Flask world.

    I’m kicking off a brand-new web application and want the entire stack set up from scratch. The backend must be built with Spring Boot, exposing clean REST endpoints and following best practices for security, logging, and testing. Data will live in a relational store—MySQL or PostgreSQL—so the schema, migrations, and repository layer should be wired for one of those engines with minimal friction to switch between them. On the front end I’m open to modern JavaScript frameworks; feel free to propose React, Angular, or another popular choice as long as it integrates smoothly with the Spring Boot API and supports responsive design. Because this is green-field work, the project will move through typical milestones: design, MVP, iterative feature drops, and deployment. I...

    Node.js Loan Backend Build

    I am assembling a new loan-processing platform and need a seasoned Node.js developer to stand up the entire backend. The core of the job is to architect and code secure user authentication and authorization, handle the full life-cycle of a loan application form, and build reliable payment processing with clear tracking of every transaction and status change. For data persistence I would like you to work with a SQL database—MySQL or PostgreSQL are both fine—so please structure your models and migrations accordingly. Beyond our own data store, the service must connect smoothly to several third-party providers: a credit-score API to pull applicant scores in real time, a payment gateway for disbursements and repayments, and notification services that let us push SMS and email upda...

    I need a browser-based back-office portal that can speak fluently to both Verifone Commander and Gilbarco Passport systems running in our forecourts. The goal is to centralise inventory, capture every transaction in real time, and give my staff role-based access without relying on the vendor-supplied desktop tools. Your experience configuring Verifone and Gilbarco is essential; the project will involve working with their XML/JSON feeds, pollers, and any available APIs to pull price books, tank levels, and sales data into a single PostgreSQL or MySQL store (I am open to your recommendation). From there, the web UI—preferably built with a mainstream framework such as React, Vue, or Angular—should present dashboards for stock levels, live transaction logs, and straightforward scr...

    I’m ready to move Catalyst from concept to a working MVP and need an experienced full-stack partner to make it happen. Catalyst will serve insurance brokers as an all-in-one operating system, replacing today’s patchwork of spreadsheets, email quote requests, and individual insurer portals. Scope of this first build The MVP must let a broker log in, create or import a client, request quotes from the major national insurers we’ll support at launch, display side-by-side comparisons, track compliance evidence automatically, and communicate outcomes back to the client—all through a single, responsive web interface that works smoothly on desktop and mobile. Core modules to deliver • Automated quoting: trigger and retrieve quotes via the insurers’ AP...

    FREELANCE DEVELOPER NEEDED – STABILIZE & IMPROVE REACT NATIVE MARKETPLACE APP (EXPO + SUPABASE + STRIPE) PROJECT OVERVIEW I am developing a peer-to-peer rental marketplace mobile application where users can list items for rent and others can book them. The concept is similar to platforms like Airbnb or Fat Llama, but focused on renting physical items between users. The application is already built and functional. The current priority is stabilizing and refining the existing system, improving reliability and UI consistency before expanding into additional features. This project is NOT about building an app from scratch. The core product already exists. The main goal now is to strengthen the existing architecture, improve stability, and polish the user experience so the platfor...

    Our production MLM binary system is built with on the front end and PostgreSQL on the back end, and I’m ready to move it forward under a monthly retainer with milestone bonuses for completed feature sets. The focus is strictly on new feature development rather than general bug fixing or performance tuning. The first major deliverable is an enhanced user dashboard. I need clean, modern UI improvements plus rock-solid commission tracking that pulls data directly from our existing genealogy tables. Advanced analytics can follow once the new layout is in place, but the commission view must be accurate and fast from day one. Alongside the dashboard, you will handle integration with selected third-party services (think payment processors, messaging platforms, or a lightweight CRM). Expe...
