I build automation systems that work reliably because I understand how software works under the hood. Unlike typical no-code builders, I am a full-stack developer. That means I can debug APIs, write custom logic, handle edge cases, and build integrations that others can’t. I work with Zapier, Make, n8n, REST APIs, webhooks, and JavaScript to connect platforms, automate operations, and eliminate manual work. Clients hire me when: • automations become too complex • data must be transformed or validated • API limits & pagination appear • custom logic is required • existing workflows keep breaking I don’t just connect tools - I engineer stable systems.
