I’m a full-stack developer and n8n automation specialist focused on turning messy workflows into reliable, automated systems. I build API integrations, web applications, and AI-powered chatbot and automation pipelines that connect CRM, HR, and content operations.

At Katalyst CRM, I built an email monitoring automation in n8n that extracts HR data from emails and syncs it to an internal project management system. I also delivered a Slack time clock integration for attendance tracking, plus AI chatbots for Facebook Messenger and Instagram that support inbound classification and CRM sync. To improve pipeline speed, I developed a Lead Intake to CRM pipeline using Vapi AI voice agents to auto-sync qualified leads from inbound calls.

At NexaOps, I created a RAG-based chatbot for Facebook Messenger that answers customer questions by retrieving context from a knowledge base, coordinated through n8n. I also built an n8n orchestration pipeline connecting Slack, Gmail, and Supabase for candidate screening, and I experimented with fine-tuned OpenAI models and RAG for resume scoring.

Earlier, as a Software Developer Intern, I built full-stack features for a knowledge-sharing web app using C# .NET alongside a small agile team, covering UI/UX, database management, and REST API integration. I’m motivated by pragmatic automation, clean integrations, and building products that save teams time while improving accuracy.
