Expert Full-Stack Developer for Web App & Custom CRM Enhancements

@Microlent

This sounds like a good fit for the way I prefer to work long-term. I have hands-on experience as a full-stack developer building and maintaining web applications, working with APIs, and integrating third-party platforms. I’ve worked with GoHighLevel automations and integrations, including webhooks, API-based workflows, and syncing data with external systems like Airtable, so I’m comfortable extending and maintaining automation-heavy setups. On the development side, I regularly debug existing codebases, add new features, and improve internal tools such as custom CRMs. I’m used to working inside partially built systems where understanding the current logic is just as important as writing new code. I can reliably work during EST hours and communicate clearly in a collaborative setup. I’m looking for a stable, long-term role where I can become familiar with the systems, take ownership of problems, and contribute consistently rather than jumping between short projects. I’m fine with the fixed monthly structure you described and open to future revenue-share opportunities as projects evolve. Happy to discuss the CRM tech stack, current GoHighLevel usage, and your preferred tools so we can confirm a good working fit. Best, Jenifer

With over a decade of experience under my belt, I am well-versed in a wide range of front-end and back-end technologies including MySQL and PHP, which are essential for your project. I have successfully developed and maintained several web applications, and my proficiency in multiple CMS platforms such as WordPress and Laravel aligns perfectly with this job. Additionally, I've used various third-party integrations like APIs for custom database management - an expertise you're seeking for your CRM enhancements. Moreover, my experience with other task automation tools like N8N will come in handy as we use GoHighLevel for automations and integrations. While you haven't specified the exact nature of Airtable use, I've also worked extensively with various databases including MongoDB, so adapting to Airtable shouldn't pose any issue. My skillset thrives in complex situations; hence, I've developed a knack for debugging and adding new features to existing systems.

A jack of all trades, they say. Well, this is Umer - and I've alleged mastery in every language you've mentioned in the project description. Whether it's whipping up full-stack web apps, integrating those with various APIs or exploring complex databases like Airtable, I'm on it! In the field for years now, my abilities have taken me from the comfortable space of back-end work to the dynamic world of front-end development like React.js and Next.js. Big plus-point is my extensive experience with GoHighLevel too! This means automations and integrations won't be a problem at all. What sets me apart from the rest? My inveterate belief in offering quality over quantity. Not only will I debug, edit and add new features to your existing CRM (Because let's be real - a real user understands how important editing can be), but also enhance its usability. I am well-versed in eastern time-hours and being flexible to communicate during your timezone won't hinder our productivity. Lastly, a project like yours needing long-term dedication attracts me profoundly and aligns well with my career aspirations. From all that you've described as job responsibilities, it appears that I'm exactly the problem solver you need on your team - just like how I've handled multiple ongoing projects before! I'm positive we can create something impactful together. So let's get started!
