I need a freelancer with experience developing chrome extensions to help with a small piece of work. I have built a POC that injects buttons into a site but need someone to get it over the line, debug, test. Please only apply if you have experience with Chrome Extensions, Javascript and APIs. Here is the example page. The goal is for buttons to be added to the two pages and when clicked it picks up the correct details (odds, match details, etc) Note that the goal is to ensure that similar functionality works for related pages (note that DOM is slightly different so needs a bit of work, possibly separate JS scripts for each page but will let you recommend best approach). Example of total page [login to view URL] Example of handicap page [login to view URL] Example of match betting page: [login to view URL]

Hi, To finalize your Chrome extension, I'll debug and test the existing POC to ensure the buttons work correctly on the specified pages. This will include: - Debugging the current implementation to fix any issues. - Ensuring buttons capture the correct details from the pages. - Testing functionality across the related pages with different DOM structures. I will approach this by reviewing the existing code, making necessary adjustments, and ensuring compatibility with the different page layouts. Ready to start once you provide access to the current code and any additional details. Thanks!

Hi there, I like how you have outlined your project description with clear examples and goals. You are looking for an experienced Chrome Extension developer to help finalize your proof of concept by debugging, testing, and enhancing button injection functionality across multiple related pages with slightly different DOM structures. The core challenge involves capturing accurate match details, odds, and other relevant data when the injected buttons are clicked. With strong expertise in Chrome Extensions, Javascript, and interacting with APIs, I have successfully delivered similar projects involving dynamic DOM manipulation and cross-page functionality. I understand the nuances of tailoring scripts for differing page structures and can recommend the best approach, whether that be modular JS files or adaptive logic, to ensure robust and maintainable performance. I will thoroughly test the extension on all provided page examples and optimize it to work seamlessly. My goal is to get your POC fully functional and polished. Please feel free to reach out so we can discuss your requirements and timelines in detail. I am excited to collaborate and help you bring this extension to completion efficiently.

Hi, We’ve developed multiple Chrome extensions that interact with external websites, including one that extracts data from a betting site and sends it to a backend for processing. This experience has equipped us with the skills to handle complex scenarios like dynamic DOM changes and ensure that extensions remain functional across different versions of Chrome. In addition to Chrome extensions, I’ve worked extensively with JavaScript frameworks such as React and Vue, where I’ve developed fully-fledged web applications that integrate with third-party APIs and utilize server-side rendering. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit. I usually respond within 10 minutes. I’m eager to learn more about your exciting project. Best regards, Adil

As a seasoned developer with broad experience spanning multiple languages including JavaScript, I am not only familiar with but proficient in Chrome extension creation. I have a thorough understanding of how to effectively use the Chrome extensions API and JavaScript to inject buttons and related functionalities as you've described. Building upon the proof of concept you've already developed, I can take your project over the finish line by debugging, testing and ensuring that functionality seamlessly extends to similar pages despite differences in DOM. My expertise in creating elegant solutions for even the most intricate requirements make me the right fit for this task. In my previous projects, I have worked on similar debugging tasks. For instance, when faced with disparate DOMs that required separate Javascript scripts, I successfully implemented appropriate solutions that achieved seamless functionality across varied web pages. This kind of adaptability is critical for addressing idiosyncrasies in web scraping projects such as yours. Not only will I bring my extensive skills to this project, but as a collaborator, I'm focused on not just meeting but exceeding client expectations. My commitment to delivering high-quality, scalable code and meeting deadlines aligns perfectly with your project's needs. Let's collaborate closely to iron out all the necessary details and get this project completed masterfully and expeditiously!

Hello. I can help you finalize your Chrome extension and stabilize the button injection logic across your target pages. I have extensive experience building extensions that interact with dynamic DOM structures and external APIs to capture sports betting data. I will debug your current proof of concept and implement a robust selector strategy to handle the variations between the total, handicap, and match betting pages. I am available to start immediately and will ensure the data extraction is accurate and the extension passes all tests. Please reach out so we can review your existing code and get this over the line. My plan involves refactoring your content scripts to use a modular approach that detects the page type and applies the specific selectors for odds and match details. I will implement mutation observers to ensure buttons are reliably injected even as the dynamic betting content loads. cheers Nehal

Hello there, I'm an experienced Chrome Extension developer with a focus on debugging, JavaScript, and API integration. I’ve built and refined extensions that inject UI elements into pages, ensuring they work across related pages with minor DOM differences. I understand the need to iterate on a POC, debug, and test thoroughly to get a reliable, production-ready solution. I’ve previously debugged extensions that inject buttons on various sport betting pages, wired them to pull odds and match details via APIs, and tested across slightly different DOM structures. My approach would be to scope per-page variants (or lightweight separate scripts if needed) while sharing a solid core for data collection, with robust error handling and clear logging for easy debugging. I can handle this work end-to-end, delivering a polished extension with clear milestones and test coverage. Best regards, Billy Bryan

Hi, I’m Juan Pablo. I’ve built and debugged Chrome extensions that inject UI elements, read dynamic DOM data, and interact with APIs across pages with different structures. You need someone to take your POC, stabilize the injection logic, ensure buttons appear on all target page types, and reliably extract odds, match details, and related data. The key challenge here is that each page type has a slightly different DOM, so selectors must be adaptive or separated into modular scripts to avoid brittle behavior. A critical detail is handling asynchronous DOM changes — many betting sites load odds dynamically, so the extension must wait for the correct nodes before attaching buttons or scraping values. My approach: – Review your current extension structure and fix injection timing and selector logic. – Implement page‑specific or unified handlers depending on DOM complexity. – Ensure accurate extraction of odds and match details across all provided URLs. – Add clean debugging, testing, and logging to validate behavior. – Package a stable, production‑ready version. I can start immediately and get your extension working reliably across all related pages.

It’s so frustrating when a Chrome extension almost works but just won’t reliably grab the right details across different pages. Spending time tweaking scripts for changing DOMs and still not having the buttons pick up odds or match data perfectly can really hold up your project. You can expect the extension to consistently add buttons to all target pages and pick up the correct match details, no matter how the DOM varies. First, I’ll review your current POC and identify exactly where the selectors or scripts need adapting. Next, I’ll adjust the code so it reliably injects buttons and collects the right data for each page type. Finally, I’ll test thoroughly to be sure it works smoothly on all similar pages. Could you let me know if there are any edge cases or specific data points that have been giving you the most trouble?
