At Finetech Consultancy, I engineered AXON, a multilingual AI voice assistant with real-time conversational logic using the Gemini Live API. I added WebRTC voice activity detection to handle interruptions and connected it to PBX networks for autonomous call routing.

I built multi-agent systems with Google ADK and A2A on Vertex AI, and designed MCP servers and tools for secure access to enterprise systems. I also trained and deployed models on Vertex AI.

For Finetech Consultancy, I designed secure RAG pipelines using Cohere and Qdrant, and implemented managed RAG with Google and Azure services. I also built agents and business workflows with Microsoft Copilot Studio, Power Automate and Microsoft Foundry.

As a freelance AI Consultant & AI Architect, I advised companies on AI architecture and deployed RAG pipelines and automation workflows. Earlier, as a QA Intern at DineTap, I tested the app and website and worked with developers to reproduce and resolve bugs.
