PROJECT OVERVIEW I am building Pipe-r, an AI-powered field-service management platform designed specifically for plumbing companies. The goal is to create a polished, scalable SaaS product that can compete with platforms such as Jobber and ServiceTitan while providing deeper plumbing-specific workflows, better automation, a faster user experience, and practical AI tools. A prototype/application shell currently exists at and was created using Base44. It establishes the product direction, interface, navigation, and portions of the intended workflow. The selected developer or agency must first audit the existing application and determine what can safely be retained, improved, migrated, or rebuilt. This is not a simple website or basic scheduling application. I need a production-ready, mu...

I want a modern, mobile-first e-commerce site built with React on the front end and a Node/Express API backed by MongoDB. The store will sell physical products, so I need a polished catalog, intuitive search, a secure customer account system (registration, login, password reset), and a friction-free cart and checkout flow. On the admin side, I need a dashboard where I can add, edit, or retire products, review orders, and manage users. Role-based access is important—regular shoppers should never touch admin routes. Please follow best practices for security (hashed passwords, JWT or similar token strategy, server-side validation, HTTPS readiness) and performance (lazy loading, code splitting, indexed queries). A clean, component-driven UI is essential; I’d like you to keep styl...

I need a seasoned PHP developer to design and build a clean, well-documented API from the ground up. The project centres entirely on backend logic—there is no front-end work—so your focus will be creating efficient endpoints, solid authentication, and clear JSON output. Here’s what I have in mind: • Code in modern PHP (8.x preferred) and follow PSR standards. • Use a framework or micro-framework you’re comfortable with—Laravel, Lumen, Slim, or even plain Composer packages are fine—as long as it stays lean and easy to maintain. • Include token-based authentication, structured error handling, and basic rate limiting. • Provide concise documentation (endpoints, parameters, responses) plus a Postman or Insomnia collection so I can...

I have an AI-enabled smart collar on every cow in my herd. The collars stream real-time health metrics and behaviour-analysis data that I want flowing straight into an ERP so I can treat each animal like a live SKU inside my wider inventory, analytics and supply-chain workflows. I have not selected the ERP platform yet; SAP, Oracle or Microsoft Dynamics are all on the table. Part of the assignment is to advise which option will connect most cleanly to the collar data pipeline and to my existing farm-management processes, then build the actual integration. The finished solution should: • pull the collar’s health and behaviour data automatically (API, MQTT or another method you recommend) • map and normalise those fields inside the chosen ERP so they support inventory m...

I need a solid PostgreSQL-backed RESTful API to drive the Solar TwinPro web application. Your task is to design the database schema and expose clean, versioned endpoints that cover full CRUD functionality for each core resource in the system. The web front-end will consume JSON, so consistent status codes and clear error handling are important. Please structure the project so it can be deployed easily (Docker preferred, but I am open to other simple approaches) and include concise documentation; an OpenAPI/Swagger spec is ideal so the front-end team can plug in without guesswork. Deliverables • PostgreSQL schema (DDL) and seed data • REST endpoints covering create, read, update, delete for all defined entities • Environment and run instructions (e.g., Dockerfile or...

I represent a marine-sector company that now needs a full digital presence—far more than a brochure site. The goal is to deliver a polished corporate website supported by an online booking engine, a content-management system our staff can run without developers, and a secure client portal that streamlines every post-booking interaction. Scope of work • Design and build a modern, mobile-first corporate website that conveys our authority in the maritime industry and is easy to navigate. • Create an end-to-end booking platform where customers can view availability in real time, select services, complete payment, and instantly receive confirmation. • Provide a CMS with role-based access so marketing and operations teams can update pages, rates, and schedules on thei...

The project centres on a streamlined, secure web platform that lets individual borrowers handle every step of a small-ticket loan online, while giving my internal team full oversight from the admin side. The front-end must be responsive so applicants can comfortably use desktop or mobile, and the back-office should feel equally intuitive for staff processing dozens of files a day. Borrower portal – required modules • Loan application form with basic KYC upload • Real-time loan status tracking once a request is submitted • Clear repayment schedule that updates automatically after disbursement Admin panel – required modules • User management (create / edit / suspend borrower accounts) • Loan approval workflow with status gates (review →...

I need a purpose-built B2B e-commerce portal that allows corporate clients and our field sales representatives to interact inside a single, secure environment. Unlike a standard storefront, the site should emphasise relationship management: every user signs up, lands on the appropriate dashboard, and can start a private conversation thread with the rep assigned to them before any order is placed. Core workflow I have in mind: • User registration & profile creation for two roles—client and sales rep. • Internal messaging so both sides can discuss pricing, availability and order details in real time. (We already manage product data in-house, so a full catalogue can be added later; the immediate focus is on the people connection.) The underlying platform simply needs...

I need a seasoned .NET backend developer to build a suite of RESTful APIs that will power our next release. The core of the job is pure API development—no UI work—so you should feel completely at home writing clean, well-structured C# code in .NET (preferably .NET 6 or later), wiring it up with Entity Framework or Dapper for data access, and documenting everything with Swagger / OpenAPI. Here’s what the APIs must handle: • User authentication (token-based, ideally JWT) • Full CRUD operations for our primary data models • Smooth third-party integrations, starting with two vendors that expose JSON endpoints I’ll provide the database schema, access credentials, and a concise list of integration endpoints on kickoff. You’ll return: 1. So...

My production C# application currently targets .NET Framework 4.8 and has started to show its age. I need it migrated to a supported, more secure runtime (ideally the latest LTS release of .NET), with every dependency updated and any obsolete APIs refactored. The primary driver is security: I want all outstanding vulnerabilities removed, HTTPS enforcement tightened, and modern authentication/cryptography practices adopted throughout the codebase. During the upgrade I also want to introduce a clean integration layer so the app can talk to external systems (REST and, if feasible, simple message-queue endpoints). This should be implemented in a way that keeps the core logic decoupled and unit-testable. Finally, a handful of persistent UI glitches—visual misalignments and sporadic cont...

I’m ready to move my Paying-Guest/hostel operations off spreadsheets and into a single, web-based platform built with .NET (C#), SQL Server or MySQL, HTML, CSS and JavaScript. The application will sit on a hybrid setup—part cloud, part on-prem—so clean separation of concerns and a painless deploy script are important. Core scope • Secure, role-based authentication for Owners, Students and Administrators, each landing on a tailored dashboard. • Property and room management with live availability, quick search and filters. • Student self-registration followed by a guided room-booking flow that updates availability in real time. • Integrated rent ledger: capture payments, show history, flag overdue amounts and let me export or print offline recei...

I need a website that brings two sides of my practice together: data-driven analysis and strategic business consultancy. On the analytics side the site must present interactive dashboards that clients can explore in real time, as well as generate automated PDF or Excel reports they can download without my intervention. For the consultancy arm, I want a polished area that highlights past client testimonials and lets prospects book an appointment directly into my calendar (Google Calendar or Outlook integration is fine). A clean, modern front-end with mobile-first design is important, and the back-end should make it simple for me to upload new datasets, create additional dashboard views, and update testimonial content without touching code. If you prefer to build in WordPress, Django, or an...

I’m building an engagement-driven marketplace that feels as easy and addictive as scrolling through Twitter, yet fully focused on buying and selling. The core of the product is a real-time social feed where every post represents an item for sale. Users will be able to list handmade goods, digital products, and second-hand items—essentially anything they wish to move—then have those listings surface in a chronological feed that other users can like, comment on, repost, or purchase from directly. I need a full Android app and a responsive web experience that stay visually in sync and share one backend. Speed and fluidity matter; the feed should refresh instantly, images should lazy-load smoothly, and notifications should land in real time. Think infinite scroll, hashtag or...

I run an IT asset disposition, reverse-logistics, electronics remarketing, and recycling operation and I need a single web-based application that keeps every device visible from the moment we collect it until it leaves our doors. The core of the build is asset tracking and management with two must-have capabilities: • Real-time location tracking – the system should update each item’s status and physical position as soon as it is scanned or moved, whether that’s during pick-up, in-transit, inside our processing areas, or on the way to resale or recycling. • Robust inventory management – dashboards that show quantities by customer, condition, lot, and warehouse zone, plus fast search and filter tools so our team can locate any serial number in seconds. ...

I’m ready to build a marketing-driven mobile application that works seamlessly on both iOS and Android. The core experience revolves around a robust booking calendar where users can register or log in, view available slots, and lock in appointments.

Key deliverables • Escrow system that keeps funds secure until both parties confirm the deal • Robust verification workflow so buyers and sellers earn a visible “Verified” badge before they trade • Support-ticket system that opens private threads for any dispute or question Beyond these essentials, the build should include: – Custom role and permission architecture (I’ll supply the exact hierarchy once we ...

I’m putting together an end-to-end payroll platform that lives on the web and pairs with a dedicated Android time-tracking app. The goal is a seamless flow of attendance data straight into payroll so every payslip is accurate the moment it is generated. On the payroll side I absolutely need automated salary calculation, built-in tax filing, and benefits management. Those core functions should draw directly from the attendance module to eliminate manual entry and reduce errors. For attendance, the Android app must capture reliable Clock-in/Clock-out data (with offline buffering if the connection drops), calculate overtime in real time, and feed Leave management back to the web dashboard so balances stay up to date. Key deliverables • Responsive web portal with admin and em...

I already run a WhatsApp Business account, but it still shows as “unverified.” I need someone who knows the Meta Business Manager flow inside-out to walk me through the remaining steps, review the documents I have prepared, and make sure the green checkmark appears without delays or rejections. Right after the verification is complete, I want the WhatsApp Cloud/API environment configured so I can launch fully automated messaging from our server. That includes generating the API keys, linking the number, setting an initial webhook, and proving that a sample template message can be sent successfully. Please have prior, hands-on experience with recent Meta/WhatsApp policy changes; I don’t want to waste requests or hit rate limits while testing. If you can finish both pie...

I’m building a computer-vision layer that can reliably recognise images and return structured results that the rest of my platform can consume. The core of the project is an AI-driven image-recognition model; I need someone who can take it from dataset preparation all the way to a callable endpoint. Here’s what success looks like for me: • A well-architected model (TensorFlow, PyTorch or comparable) trained on the dataset I’ll supply—or augmented with open-source sets you recommend—to reach an agreed accuracy threshold. • Clean, readable Python code with clear comments and a short README so future team members can retrain or fine-tune the model. • A lightweight API or Dockerised service that I can spin up on AWS/GCP and hit with a POST requ...
