AI-Expert Software Developer for Business Application

Send me sample of your best work. I am looking for a highly experienced software developer to complete, improve, test, and commercially launch an existing proprietary business software application. To protect the project, the public posting will not disclose the software's industry, proprietary business logic, unique features, calculations, workflows, or competitive strategy. Full details will be shared only with bidders I am seriously considering. I would like my project done in 8 to 10 days. The developer must be an expert in AI-assisted and AI-generated code and must be capable of auditing existing code rather than assuming generated code is correct. You must identify and fix incomplete, broken, inaccurate, unreliable, or poorly designed functions and build any missing features required by the final specifications. This is not simply a coding assignment. The selected developer will be responsible for making the complete product work from end to end, including the software, user interface, local data/storage functions, calculations, reports, imports/exports, backups, licensing/subscription connections, website integration, downloads/delivery, and any required third-party service connections. Required Experience • Expert-level software development and debugging experience. • Strong experience reviewing, correcting, and completing AI-generated or AI-assisted code. • Experience with professional business/financial applications, dashboards, calculations, reporting, local data storage, CSV/Excel import/export, backup/restore, and PDF/document output. • Strong GUI/UX skills. The finished program must be extremely user friendly, with important functions easy to find and logically organized. • Experience integrating commercial software with websites, subscription/payment systems, licensing/activation systems, downloads, account communications, and other services when required. • Ability to test realistic end-to-end workflows and prove that every required feature actually works. Testing & Demonstration Requirements The developer must test and verify every feature, button, calculation, workflow, import/export, report, backup/restore function, integration, website connection, and commercial purchase/delivery process. Any failure must be fixed and retested. The developer must also provide clear step-by-step demonstrations using the actual working software and realistic business examples. I need to see what information is entered, what each feature does, the result it produces, and how a real customer would use it. Mockups or demonstrations of features that do not actually work are not acceptable. Agreements Before receiving the confidential project files and full specifications, the selected developer must sign my Non-Reverse Engineering Agreement and Work Made for Hire Agreement, along with any other required confidentiality/IP agreement. When Applying • Describe your experience completing or repairing AI-generated software. • Provide examples of comparable business software you personally developed. • Explain your testing/QA process. • Confirm that you can handle website deployment, integrations, subscription/licensing setup, and commercial launch testing. • Confirm that you can create step-by-step demonstration videos using realistic examples and the actual working software. I will own the full and exclusive copyrights to all software, text, sound, images, raw files, source files, project files, and all work created for me. I will keep all work you provide the software, text, sound, images, raw files, source files, project files, and all work created for me. and I will own all copyrights to all work. I will release the full milestone when the software is completed, delivered, and accepted by me. I do not pay any milestones until software, source code is completed, all files delivered, all testing, all fixes, all features, all setup, all screen capture videos, are completed and accepted by me. If your work is High Quality and exactly what I need I would be interested in considering you for Future projects. I don't communicate on Sundays and I don't expect you to work on Sundays.
