Database Development Jobs

I’m building a new content-management system and want a clean, well-structured MySQL schema engineered from the ground up. The brief is limited to database design only—no optimization or migration work is needed at this stage. The CMS will store core entities such as posts, pages, categories, users, roles, and whatever other tables you feel are necessary to keep the data normalized and future-proof. I’m open about the exact content types the system may handle later on, so please keep the structure flexible enough to add multimedia or user-generated modules without major refactoring. What I need from you • An ER diagram in PDF or PNG • MySQL-compatible CREATE TABLE scripts with primary/foreign keys, indexes, and constraints clearly defined • A short ...

I need a developer (or small team) to build a single, integrated hospital management solution that covers every daily workflow in our mid-sized facility. At the heart of the system you’ll create robust modules for patient registration, clinical records, ward/bed allocation, stock control for the pharmacy and general stores, and a seamless billing engine that handles both cash and insurance cases. The patient, inventory, and billing features are non-negotiable pillars of the project. On top of those, I also want a fully fledged pharmacy management add-on with its own POS-style billing interface, as well as secure telecommunication and teleconsultation capabilities so our doctors can conduct virtual follow-ups directly from the platform. All modules must talk to one another through a ...

We have a supabase project that consists of multiple tables consisting of product, pricing, and image data. To simplify integration for external users via API (e.g. clients, partners, 3rd-party platforms), a consolidated and secure API needs to be created. This will expose key product information via a single, well-structured endpoint, backed by a new consolidated table in Supabase. Project Objectives: 1)To design and implement a single, external-facing API that provides access to the supplier’s key product, pricing, and image data. 2) To create a new consolidated Supabase table that aggregates essential fields from around 8-12 existing tables, enabling access with one API configuration rather than multiple joins. Any data changes to the main tables needs to reflect onto the sin...

I need a detailed, up-to-date directory of U.S. grant programs that fund home repairs and rehab projects anywhere in the country. My priority is locating opportunities that pay for structural repairs, energy-efficiency upgrades, and aesthetic improvements, but I’m open to any program that ultimately reduces out-of-pocket costs for homeowners. What I’d like from you – A spreadsheet or database that lists every relevant grant you find, one row per program. – For each entry: the administering agency, contact details, award range, matching-fund rules, current application window, eligibility notes, and a direct link to the official application page or PDF. – A short summary outlining which programs appear strongest for someone tackling a full-scale renovatio...

I want to consolidate every day-to-day management activity into one bespoke application that will streamline operations, surface clear insights, and free my staff from juggling spreadsheets and disconnected tools. The software’s single, non-negotiable goal is effective business management; everything else—feature depth, tech stack, and preferred platform (desktop, web, mobile, or a smart blend of these)—can be shaped once you understand how my team actually works. Security, future-proof architecture, and straightforward maintenance are must-haves. At the end of the project I will need the full, version-controlled source code, concise documentation that allows an internal developer to pick up the project seamlessly, and a brief hand-over session to walk me through deploym...

I have a PHP-based Activecode admin panel that currently talks to an IPTV Xtream-Codes backend. I need the same interface re-wired so it communicates flawlessly with an XUI One installation instead. You’ll be working with two different database schemas: the Xtream layout already in the code and the XUI One tables detailed in the complete documentation I’ll supply. Core objectives • Replace every Xtream-specific query, endpoint call, and table reference with its XUI One equivalent. • Preserve all existing functionality exactly as today’s users experience it. • Introduce a new Stream Monitoring section so I can see real-time status and basic stats for each channel directly from the panel. All code must stay in PHP, follow the project’s curre...

I need a small utility—either a lightweight desktop app or a background service—that can connect to my existing SQL database and push data into clean, well-structured .qdb files. The tool must work from predefined queries; that is the core workflow I want. Once a query is executed the utility should automatically narrow the result set using two criteria I choose up front: data type and specific column values. The generated file must follow a consistent schema so a downstream system can consume it immediately. While optional .csv support is welcome, .qdb export is the priority. Connectivity via standard ODBC/JDBC, the ability to run on a schedule or by command-line/REST trigger, clear logging, and straightforward configuration (plain-text or simple UI) are all important for ...

I’m kicking off a data-management initiative and need a seasoned professional to help turn scattered information into a reliable, well-structured asset. The first step will be a short discovery session where you review what I already have, flag obvious quality or consistency issues, and outline practical options for organizing and maintaining the data going forward. Once we agree on the approach, you’ll implement it end-to-end—setting up the storage environment, configuring validation rules, and documenting the workflow so it’s easy for me (or future staff) to update and extract information whenever needed. I’m flexible on the specific tools; cloud databases, spreadsheets, or a lightweight ETL solution are all on the table as long as they fit the scale of the...

For the next two to three weeks I need an experienced auditor to verify every piece of IT equipment across our office and record the results directly into our existing asset-management software. You will have full access to the system on day one, so proficiency with standard asset-tracking platforms is essential; no new tool purchase is required on our side. Scope of work • Physically locate and tag all laptops, desktops, servers, networking gear and peripherals • Confirm and correct serial numbers, asset IDs, locations and user assignments in the software • Flag discrepancies or missing items immediately so we can investigate while you are still onsite • Capture any supporting photos and attach them to the asset records Deliverables 1. A fully updated, reconcil...

I’m looking for someone who already feels at home in Drawio to turn my written specifications into a clean, well-structured UML class diagram. I’ll supply the complete naming convention and style guide up front, so your main focus will be translating the classes, attributes, methods, and relationships into Drawio while keeping everything aligned with that guide. Accuracy is more important than speed: every association, multiplicity, and visibility modifier needs to match what I provide. Once the diagram is laid out, I’d like the original .drawio file along with an exported PNG (or PDF if you prefer). If you spot any logical gaps or see a tidier layout, feel free to suggest it before final delivery—I’m open to improvements as long as the agreed conventions sta...

I am building a web-based freight exchange that focuses exclusively on carriers. The goal is to let any registered carrier log in, search live cargo listings, and book loads in just a few clicks. A clean, intuitive interface is essential; most of my users are on the road and will access the site from mobile devices. Scope of work • End-to-end development from a blank repo: UX/UI design, responsive front-end, RESTful (or GraphQL) back-end, database schema, and deployment pipeline. • Core features for carriers: searchable load board with filters (origin, destination, weight, dimensions, dates), real-time availability, and one-step booking/confirmation. • Authentication: simple e-mail/password login with session management is enough; I do not need 2FA at this stage. &b...

I need a straightforward, browser-based database that holds every personal contact I’ve collected from 2020 through 2024. Each record only requires two fields—name and phone number—so the interface can stay minimal: add, edit, delete, and quick search. Once the data is in place, I also want a matching ledger file I can download at any time (CSV or Excel is fine) so I always have an offline backup of the same 2020-2024 contacts. Deliverables • Web app running locally or on a basic shared host (any mainstream stack is acceptable). • Imported contact data and the ability for me to keep adding more. • Exported ledger file with all current records. • Short read-me covering setup and basic maintenance. I’m ready to start right away and would...

I need a mobile application that helps tutors and students find one another quickly and keep every step of the conversation inside the same platform. At its heart the app must handle two distinct yet connected user groups—tutors and students—allowing each to create a dedicated profile and appear in search results for the other. Core features to be delivered • Search functionality: fast, filterable searches so users can narrow results by subject, level, location, price or any other basic parameter we agree on. • Profile creation & management: separate flows for tutors and students with photos, short bios, subject tags and editable availability. • Messaging system: real-time, in-app chat that supports text and basic file exchange to schedule lessons and ...

I need clean, maintainable native SQLScript and table functions created directly in SAP HANA, then thoroughly debugged and tuned. The work spans new development as well as refactoring existing code that is currently suffering from slow execution and other inefficiencies. What matters most is deep, hands-on experience with SAP Native HANA: SQLScript syntax, table functions, performance-oriented design patterns, execution plans, and built-in debugging tools such as PlanViz, SQL Analyzer, and tracing. Code must follow SAP best practices, leverage equivalent CE functions where appropriate, and remain easy for a team member to pick up later. Deliverables • Fully working SQL scripts / table functions that meet the stated business logic • Documented changes or fixes for any performa...

I’m looking for an experienced developer to turn a repetitive business-operations workflow into a fully automated software solution. This is a pure software-development job whose primary objective is to eliminate manual steps, reduce errors, and free up staff time. We’ll start by mapping the current process together so you understand the exact touch-points, decision rules, and data hand-offs. From there, you’ll design and build an application that runs those steps end-to-end with minimal human input. Clean code, clear structure, and maintainability are important to me—I’d like to be able to extend the system later without a full rewrite. Please be comfortable choosing an appropriate stack, integrating with common APIs or databases when sensible, and packagin...
