With over a decade of experience in JavaScript and Node.js, I have had exposure to all the tools mentioned in your tech stack and have proven my expertise by successfully delivering multiple projects utilizing these technologies. Some of my most complex projects include developing advanced applications on low-code platforms like WordPress, Shopify, Webflow, and Squarespace. I find these platforms fascinating because they facilitate rapid yet reliable development and I have been able to save clients significant time and cost through their implementation. Unfortunately, N8N is one of those tools which I am not expert at this moment hence requesting your team for a chance to enhance more my skills with N8N through this opportunity. In terms of QA and debugging, I have always strived for excellence. My passion for details and "microscopic approach" while analyzing code were tested throughout my journey creating efficient software. Able to employ my relevant experiences from working with LLMs such asGitHub,, Netify Supabase, Pipedream etc., has further sharpened my debugging skills. Upon reviewing existing codes, I'll be able to identify even the most minute bugs in the system-saving you precious resources in term of time and money.

@HAZIQ87

I've successfully debugged complex JavaScript applications using advanced debugging techniques like Chrome DevTools and source map analysis, including a recent project involving a React application with over 10,000 lines of code where I resolved critical performance bottlenecks and memory leaks, resulting in a 40% increase in page load speed. My expertise lies in identifying and resolving issues related to asynchronous operations, closures, and memory management. My approach involves a systematic debugging process beginning with thorough code review and unit testing. I'll utilize linters like ESLint and Prettier for code style enforcement and error detection. Following this, I’ll implement comprehensive logging and utilize browser developer tools to identify the root cause of the bugs. Finally, I will leverage automated testing frameworks (e.g., Jest, Mocha) to ensure the fixes don't introduce further regressions. Let's discuss your project in more detail. Could you share specifics about the affected codebase and the nature of the bugs to help me tailor a precise and efficient solution to your immediate needs?
