Full-Stack Developer | AI Automation, APIs, CRM & Integrations

Need a workflow automated, two systems connected, or a custom tool built around the way your business actually works? I build full-stack applications, integrations, and automations for businesses that have outgrown manual processes, disconnected software, or repetitive administrative work. My projects typically involve connecting existing platforms, moving data between systems, automating business workflows, or building custom functionality where an off-the-shelf solution isn't enough. SERVICES • Full-stack web applications • API development and third-party integrations • CRM integrations and custom workflows • Business process and workflow automation • OpenAI API integrations and AI-powered features • Dashboards, admin panels, and customer portals • Payment and data synchronization • Existing application troubleshooting and improvements • Docker and self-hosted deployments TECHNOLOGIES JavaScript • TypeScript • Next.js • Node.js • PHP • MySQL • APIs • Docker • CRM platforms • Automation tools A lot of my work happens between systems rather than inside just one application. That might mean connecting a website to a CRM, synchronizing customer or payment data, automating what happens after a form submission, integrating an external API, or replacing a manual process with a purpose-built tool. I’m comfortable working with both the technical side of a project and the business problem behind it. Before building something, I want to understand what is slowing you down, what your existing systems already handle, and where custom development will actually make a difference. If you have a workflow that takes too much manual effort, systems that should be communicating but aren't, or an application you want to build or improve, send me the details and I can help determine the best way to approach it.
