I build AI powered automations that eliminate repetitive work, connect business systems and turn manual processes into intelligent workflows. I specialize in AI automation AI agents, n8n workflows, API integrations and business process automation. I help businesses automate repetitive operations, connect their existing tools, process information with AI, and create reliable workflows that save time and reduce manual effort. What I build: • AI powered workflows • AI agents & assistants • n8n automations • API & webhook integrations • CRM & lead automation • Data processing & enrichment • Email & document automation • Business process automation • AI powered customer workflows • Custom AI integrations My approach starts with understanding the existing process, identifying where automation can create the most value, and then connecting the right AI models, APIs, applications and business tools. I also use AI tools throughout my development workflow for research, debugging, testing, documentation and development acceleration while keeping the workflow architecture, implementation and final quality control hands on. Whether you have a repetitive process that needs to be automated, multiple systems that need to communicate, or an AI idea that needs to become a working workflow, I can help turn it into a practical solution.
