You will get GCP Vertex AI Agents | Secure State & History Management
Top Rated
Project details
I design and deliver production-ready agentic AI systems built entirely on Google Cloud Platform's Vertex AI infrastructure. The engagement covers end-to-end architecture and implementation — from LLM orchestration and tool use to robust state management, conversation history, and GCP-native security hardening.
What's Included
• Agentic System Architecture
Design and implementation of multi-step AI agents using Vertex AI (Gemini models), including tool calling, function routing, and orchestration logic — whether single-agent or multi-agent workflows.
• State Management
Reliable, scalable state handling across agent sessions using GCP-native services (Cloud Spanner, Firestore, or Cloud SQL depending on your requirements). Covers session state, agent memory, and intermediate task state with proper isolation and concurrency control.
• History Management
Full conversation and execution history logging — queryable, auditable, and optimized for both retrieval (RAG-style) and analytics. Built on BigQuery or Cloud Storage with structured schemas tailored to your use case.

Chrome Plugin Tool V2 (Keywordme)
Great experience working with Pankaj. He understood the requirements quickly, communicated clearly, and delivered a solid, well-built Chrome extension on time. Any feedback or tweaks were handled fast and professionally. Highly recommend and would definitely work with him again. Will be using him for all my projects going forward

Hello, I want to create a website for farms. Is this possible?
Hi Pankaj,
I hope you are doing well. I just wanted to say that I really value your role in our project. For me, Uretia is an important long–term product and I see you as the main architect of this platform.
I appreciate the effort and time you are putting into the work. What matters most to me is clear communication, realistic timelines and steady progress. If at any point you feel that something can be done in a better way – technically or in terms of process – please feel free to share your ideas. I am always open to your professional suggestions.
My goal is that we build a product together that both of us can proudly show in our portfolios. If you need anything from my side (content, decisions, priorities, clarifications), please let me know and I will support you as quickly as possible.
Thank you again for your collaboration and commitment,
Orhan
