Most businesses donât need just another chatbot, they need end-to-end AI systems that think, integrate, and execute.
I specialize in building custom AI agents and automation platforms (code & no-code) that streamline operations across sales, marketing, and support. With a background in full-stack development, Iâve shifted focus to AI and now deliver production-ready solutions that save time, reduce costs, and generate revenue.
Achievements & Results:
â Saved clients 20â30+ hours per week by automating customer support, appointment scheduling, lead follow-ups, and internal business processes with AI agents.
â Improved lead response times by up to 90% through AI voice agents, WhatsApp sales agents, automated follow-up systems, and CRM integrations.
â Reduced repetitive manual work by up to 80% using AI call answering agents, employee help desk assistants, knowledge base chatbots, and workflow automation.
â Built 30+ AI agents and automation systems, including voice AI, customer support agents, appointment booking agents, RAG chatbots, call automation systems, and multi-agent business workflows.
