    I’m ready to turn a new content-management concept into a fully-functioning web application and need a product engineer who can own the software side from first sketch to production launch. The core goal is to let non-technical users create, edit, organise and publish content through an intuitive browser interface, backed by a solid, scalable architecture. You would guide the technical vision, select the most appropriate stack, set up the database schema, craft the front-end experience and stitch everything together with clean, well-documented code. Secure authentication, role-based permissions, media handling, version control and a straightforward editorial workflow all have to feel seamless for the end user. An API layer for future integrations and basic analytics would be a big p...

    I need an e-commerce website built from the ground up that lets visitors locate items quickly through a fast, accurate product-search feature. Everything from the storefront layout to the backend catalogue management should revolve around that smooth search experience so customers can reach any product in only a few keystrokes. Core requirements • Modern, responsive design that works on mobile and desktop • A well-structured product database and search algorithm (live suggestions, filters, typo tolerance) • Easy dashboard where I can add or update products without touching code While user reviews and a full shopping-cart flow could be added later, the initial milestone focuses on putting the catalogue online and making search flawless. Tech stack is flexible—S...

    I need a clean, well-structured MySQL database that covers the essentials of a small banking operation. The core modules are: • Account management – creation, updates, balance handling, status flags • Transaction tracking – deposits, withdrawals, transfers, full audit trail with timestamps • Customer information management – personal details, KYC fields, contact history The schema must support three user groups: bank employees, customers, and administrators, each with the right level of access control that can later be tied to an application layer. Deliverables I expect 1. Normalised ER diagram (PDF or image) 2. SQL scripts to create all tables, indexes, constraints, and sample seed data 3. A concise set of stored procedures or views that dem...

    CANONICAL DATA MODEL Hello, What caught my attention in your project is that the real problem is not simply completing missing features. You already have a product. The challenge is that several parts of that product are beginning to behave as independent systems when they should be operating from the same source of truth. SipVault, the Document Hub, and Form Configuration should not merely exchange data. They should share a coherent domain model. That is where I would begin. Before changing production behavior, I would inspect the current React / TypeScript / Node.js / PostgreSQL implementation, map the existing entities and relationships, identify duplicated or conflicting models, and define the canonical structure that the rest of the application should depend on. From there, the...

    I’m working on a database-centric project that touches several parts of our tech stack, and I’d like a hand tightening everything up. The core of the work is MySQL—designing tables, refining queries, and making sure data flows smoothly—but the surrounding codebase is written in Java, Python, C++, C#, JavaScript, HTML, and a little Assembly for low-level routines. Here’s what I need: • Review and optimise the current MySQL schema, indexes, and stored procedures. • Write or clean up data-access layers in Java and Python, with light C++/C# bindings where needed. • Build small JavaScript/HTML utilities that visualise or test the data endpoints. • Ensure each language layer stays in sync after the database changes (compilation checks,...

    I’m developing a professional-networking platform exclusively for Android and need the full application coded and ready for launch on Google Play. The core experience centres on meaningful professional connections, so fluid in-app messaging is essential. Users must be able to start one-to-one or group chats instantly and exchange photos or short videos without noticeable delay or quality loss. All accounts will be created and secured through phone-number verification; no email or third-party social logins are planned, so the onboarding flow has to handle SMS code delivery, validation, and graceful error handling. Once inside, users can update a quick profile, search or receive suggestions, start a chat, and share media directly from the camera or gallery. Backend architecture, da...

    I need a custom inventory-management system tailored to the daily realities of my building sites. At any moment I want to know exactly how much cement, rebar, timber, and fixtures are sitting on each location, what was consumed today, and what must be reordered before work stalls. A clean web dashboard (ideally with a companion mobile view for site supervisors) should let us: • Create and edit material SKUs, units, and supplier data • Record deliveries, issues to crews, and site-to-site transfers—barcode or RFID scanning would be a plus • Watch live stock levels with low-threshold alerts by email or push notification • Generate daily, weekly, and per-site usage reports exportable to Excel/PDF • Control access by role so that foremen, storekeepers, ...

    I need a seasoned SSRS developer to turn a SQL Server data set into a polished compliance-audit report. My top priority is the visual structure—nested tablixes, precise grouping, conditional colour cues, warning/approval symbols, image placeholders, and reliable page breaks all have to work together so the PDF reads like a board-ready document. You will receive the database objects, sample data, and a style guide. From there, build the RDL yourself (no AI-generated one-click templates), and keep notes on why each region, expression, and parameter exists; I’ll ask you to walk me through that reasoning once the draft is ready. Deliverables • Production-ready .rdl file matching the style guide • A short design brief (1–2 pages) explaining layout choices, key expr...

    I’m building an online colour-prediction game modelled on Fiewin and need a complete web solution. The first release must run smoothly in the browser, be fully responsive, and allow each player to create and maintain a personal profile—user profile management is the one interface feature that is mandatory for now. The standout requirement is automated payouts. When a player’s withdrawal request is approved, the system should trigger an API call to my bank’s transfer gateway, confirm the response, then update the internal wallet balance without any manual step. Please architect the payment layer so that other processors such as PayPal or Stripe could be added later without a rewrite. Core scope • Secure sign-up / login, basic KYC fields, editable profile &...

    Hiring a Developer on Monthly Basis I am building a multi-page web application that streamlines several internal accounting tasks and I need an extra set of expert hands. The core stack is PHP on the server side with plenty of JavaScript and jQuery driving the client interactions, so confidence in those technologies is essential. Familiarity with common accounting concepts—ledgers, journals, reconciliations, simple reporting—will help you grasp the business rules more quickly and keep revisions to a minimum. The project is strictly web-development focused: database models and rough page wireframes already exist, but they still need to be polished, connected, and made production-ready. You would help me: • Wire the remaining PHP controllers to MySQL tables. • Craf...

    I am building an e-commerce webpage in Java focused solely on selling services rather than physical or digital goods. The platform has to feel seamless to a client who lands, chooses a service, books a time slot, pays, and leaves feedback—all in one visit. The three cornerstones of the build are: • Booking system – real-time availability, calendar view, and confirmation emails. • Secure payment gateway integration – Stripe, PayPal, or a comparable Java-friendly API, with SSL and clear error handling. • Customer reviews – star ratings and text comments tied to each service, stored and displayed in a way that is search-engine friendly. Tech stack choices remain flexible, but a modern Java backend (Spring Boot, Jakarta EE, or similar) is expected. ...
