Backend Dev Needed for PaidFamily Platform – API & Real-Time Integration Hi, I’m looking for an experienced backend developer to integrate APIs and real-time features for my platform. All UI templates (HTML/CSS/JS) are fully built and ready. Your role will be to handle backend development, integrations, and making the system fully functional. ⸻ Key Features Needing Implementation 1. Call / Communication System (Most Critical) * Outbound call creation via provider (Twilio / Plivo / similar) * Caller ID configuration using custom caller ID spoofing and real-time call control features * Real-time call control (answer, hangup, DTMF input handling) * Multi-language voice support (TTS integration) * Call recording storage & retrieval * Call flow / verification workflows...
I’m creating a brand-new application and need a single developer who can own the entire stack. The work spans the full journey—from crafting a polished, responsive front-end to wiring up robust back-end APIs, shaping the data layer in MongoDB, and finally deploying everything on AWS. MongoDB is the non-negotiable database for this project. For the rest of the stack (React.js, Node.js, or any comparable modern framework), I’m flexible as long as performance, scalability, and clean code standards are met. Deliverables • A fully-functioning application deployed to an AWS account I’ll provide • Well-structured MongoDB schema and seed data • Source code in a Git repository with clear commit history • Concise setup & deployment documentatio...
I have a custom-built e-commerce store hosted on Hostinger. I already own the domain; what’s missing is a proper server-side configuration so the URL loads the storefront and every feature can read and write to my MongoDB database. Here’s the situation: • The files are on my Hostinger VPS. • The domain’s DNS is active but not yet pointing to the right place. • The store’s back-end expects a live MongoDB connection (I have connection string and credentials ready). Your task is to: 1. Configure the domain and any necessary A/AAAA/CNAME records so the site resolves cleanly over HTTPS. 2. Adjust Hostinger’s server settings (Nginx/Apache, SSL via Let’s Encrypt, or whichever stack you prefer) so requests hit the correct build folde...
We are looking for a developer to make improvements to our existing Qbank (question bank) admin panel and backend system made in react, node js and mongodb. Project Scope: Rich Text Support for Options: Currently, our question and explanation fields already use a rich text editor. We need to extend the same functionality to the answer options (A, B, C, D). The solution should support formatting such as tables, bold text, images, and basic styling. Ensure proper rendering of formatted content on the frontend. Video Feature Integration: Add support for video content in questions. Preferred approach: allow embedding via video URL (YouTube/Vimeo or similar). Optional: simple video upload feature if feasible within budget. Display videos properly in the frontend question view. Requi...
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...
I need a clean, well-structured Node.js backend to power a real estate platform. The server must expose RESTful endpoints (or GraphQL if you prefer) that handle two core domains: 1. Property listings management • Advanced search and filter capabilities so users can narrow results by location, price, bedrooms, and any custom attributes I add later. • Image and video gallery support for each listing, stored locally or in a cloud bucket, with URLs returned in the payload. • Dedicated property detail pages delivered through the API so the frontend team can render full descriptions, media, and agent contact information in one request. 2. User authentication & profile management • Secure sign-up, login, password reset, and token refresh. • ...

I have a clear technical document ready and need a developer to turn it into a working full-stack real-estate site on the MERN stack. The project is not about flashy visuals; it is about reliable, maintainable code and a solid user experience.

Our cloud-based accounting platform is built entirely with a JavaScript/Node.js back-end on top of MongoDB. During closed beta everything behaved, but the moment we opened the doors to a larger audience the application locks up under load—no gradual slowdown, just a complete system freeze that forces a hard restart. I need a seasoned engineer who can dedicate roughly 5–6 hours every day for at least the next three months to hunt down the root causes and redesign the platform so it scales smoothly. You’ll collaborate directly with me and two in-house developers; we work on GitHub, communicate over Slack, and deploy through a basic CI pipeline that will probably need tightening as part of this project. Key objectives 1. Diagnose and eliminate the freeze: trace blockin...
I already have GenieACS v1.2.16 installed but need it taken far beyond the default install so every Airtel-supplied router in the field can be managed from a single pane. The job centres on advanced customisation, with special emphasis on two capabilities: • Firmware management – automated upgrade/downgrade workflows with model-specific images, version checks and fallback logic • Remote diagnostics – on-demand and scheduled health checks, log pulls and KPI reporting, surfaced in the GenieACS UI or via API You will be working directly on my server, so tight, well-commented presets, provisioning scripts, custom parameters and TR-069 profiles are essential. I expect clean integration with the existing MongoDB and Redis back end, zero-downtime roll-out to live devices...
I need a clean, responsive hotel-booking website built with HTML5, CSS3, Bootstrap and vanilla JavaScript, backed by MongoDB for data storage. The core of the project is a room-booking workflow that lets guests pick their dates, see live availability and receive instant confirmation the moment their reservation is written to the database. Alongside the booking flow I also want a dedicated Photo Gallery so visitors can browse high-quality images of each room and the property before they commit. Key deliverables • Front-end pages: home/landing, room listings, room detail with booking form, instant confirmation splash, photo gallery, and a basic success page. • JavaScript-powered availability checker that reads and writes to MongoDB in real time. • MongoDB schema fo...

The project covers everything from setting up the back-end architecture to delivering a polished, responsive front-end that works flawlessly on desktop and mobile.

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’m building an end-to-end website for SRPP Polytechnic Institute and want it written entirely with Node.js, Express, MongoDB, and EJS templating. The scope is straightforward but complete: The core of the site is an open-access student portal paired with a course-management section. Because I don’t need user authentication at this stage, every visitor should land straight into the content without being asked to log in or create an account. The course area simply needs to present detailed college information for each programme—title, overview, syllabus highlights, credits, faculty contacts, and any downloadable PDFs—while allowing me to add, edit, or retire courses from an admin back-office. Although the event calendar is not a must-have right now, please architec...
