I have a partially built web application made with git hub and google api keys with a solid baseline of code and clear ideas for the remaining features, yet the core functionality still isn’t working as expected. I’m looking for a developer who can dive into the existing repository, diagnose what’s breaking, and carry the project through to a fully operational state. You’ll receive the current codebase, detailed notes on intended behaviour, and access to the dev environment. Your main focus is resolving functionality issues—whether they stem from logic errors, mis-wired API calls, or incomplete server-side processes—and then polishing the pieces so everything runs smoothly from end to end. Deliverables • A fully functioning build that matches the outlined feature set • Clean, well-commented code reflecting any changes made • A short hand-off document (or inline README) explaining setup, key components, and next steps I can take on my own I’m happy to answer questions about frameworks, libraries, and hosting once we connect, and I can give quick feedback throughout the process to keep momentum high. If this sounds straightforward to you, let’s get the app over the finish line.

Hi, I can help you take this app from “partially working” to properly functional. I’m comfortable jumping into an existing codebase, tracing broken logic, API integration issues, and incomplete backend processes, then cleaning things up so the whole flow works end to end. I’ll also keep the code organized and documented so it’s easier for you to maintain afterward. If you want, I can review the current setup and outline the likely problem areas before we begin.

Hi — Elias here from Miami. I see you have a partially built web application that needs fixing. The goal is to ensure it functions seamlessly and meets your expectations without introducing new issues. What usually matters most here is the integration of components while maintaining clean code and future scalability. A common issue in systems like this is managing dependencies and securely handling API keys. The tricky part is ensuring effective communication between the frontend and backend, especially with complex workflows. My approach would involve reviewing the existing code to identify gaps or potential pitfalls. I’d focus on structuring the application for stability and maintainability, ensuring we’re not just patching up but also future-proofing the system for upcoming features. I’ve worked on similar web applications requiring careful API integration and have navigated the complexities of Git for version control. This experience helps me foresee potential risks and address them proactively. A few questions to better understand the scope: Q1 – What specific functionalities are currently incomplete, and what are your priorities? Q2 – Are there specific user roles or permissions to implement? Q3 – How do you envision the integration with Google APIs working? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hi! This is something we can definitely take on. Before jumping in, I'd want to understand what we're actually dealing with — what does the app do, and what's the core functionality that isn't working? Knowing that upfront helps me gauge the effort honestly rather than guessing. Also, what's the stack — is it mostly PHP, Node.js, or a mix? And are the GitHub and Google API integrations central to what's broken, or more peripheral? Happy to review the repo once we connect and give you a real picture of what it'll take.

Hi, this sounds like a practical fix-and-complete project rather than a vague rebuild, which is good because it means we can move faster once I inspect the repository. I can work through the current implementation, pinpoint why the core functionality is failing, and then polish the remaining pieces so the app behaves the way your notes describe. I’ll also provide clear documentation for setup and future edits on your side. If needed, I’m available for a call through the platform as well.

Hello!, I am a US-based senior software engineer(frontend, backend, ecommerce, etc) with 15+ years of experience in PHP, JavaScript, Node.js, HTML, Git, API integration, and full-stack web app debugging. I read your project carefully and understand you already have a partially built web application with GitHub and Google API keys in place, so this is less about starting over and more about identifying what’s broken, tightening the architecture, and getting the app finished cleanly. Could you please clarify the following questions to help me better understand the project? 1) What exact part is incomplete right now: frontend UI, backend logic, API auth, or deployment? 2) Are the Google API keys already connected and working, or is the issue around setup/callbacks/scopes? 3) Do you want this fixed with the current codebase only, or are small refactors acceptable if they improve stability? My approach would be: - review the repo and run the app locally - trace the broken flow end to end - fix the incomplete pieces without disrupting the solid baseline - test the final behavior and provide a clean handoff I’ve done similar work on smaller SaaS tools and internal web apps like a booking dashboard, a CRM sync tool, and a Google Sheets automation panel. I’m the kind of person who pays attention to details early, so you don’t end up with a half-finished fix. If you want someone who can jump in, understand the current code fast, and close the gaps properly, I’d be glad to help.

Your core functionality is likely failing at the integration points, not the unfinished features. The first thing I'd do is trace the request flow end to end to find where the logic breaks—whether that's API calls, server-side processing, or how the existing pieces are wired together. Once the root cause is clear, I'd fix the underlying issue rather than patch symptoms, then clean up the surrounding code so the application behaves consistently. With Git, I'd keep changes organized and leave the codebase easier to maintain, along with a concise hand-off document covering setup and the key moving parts. One thing I'd want to confirm early is where the failure first appears: does the data stop before reaching the backend, or does it make the round trip and return an unexpected result? That answer usually narrows the investigation very quickly.
