Project details
🛠 One Engine • 🥅 Three Walls • 👷♂️Three Audiences • 🚫Zero Leakage
After Week 1's AI Onboarding Automation, I wanted to explore a different challenge:
🔐 Three Tokens. Three Knowledge Lanes.
👤 Consumer Token
Access to pricing, products, FAQs and SLA information
Knowledge sourced from PostgreSQL
Delivered through Web Chat or Telegram
🏢 Internal Token
Access to HR policies, SOPs, compliance and procurement documents
Knowledge sourced from SharePoint
Delivered through Microsoft Teams
🤝 Vendor Token
Access to contracts, specifications and onboarding packs
Knowledge sourced from Google Drive
Delivered through partner experiences
✅ Consumers cannot retrieve employee data
✅ Employees cannot retrieve vendor content
✅ Vendors cannot access internal documentation
The isolation is enforced by the retrieval engine itself—not by prompts.
💼 Business Use Cases
✔ Employee Knowledge Assistants
✔ Customer Self-Service Bots
✔ Vendor Portals
✔ Policy & Compliance Search
✔ Procurement Knowledge Hubs
✔ Service Desk Automation
✔ Product Documentation Assistants

Power Apps Implementation
I've worked with Sukumar since July 2023 on a complex, multi-year ERP build, and he's one of the best developers I've partnered with across my long career. He's deeply skilled across the Power Platform stack, especially Dataverse, Power Automate, and Power Pages. He handled everything from FetchXML and OData queries to flow development and environment management across Dev, UAT, and Prod. His turnaround speed is excellent without sacrificing quality. We held standups five mornings a week at 7 AM, and on weekends when necessary and he never missed one, always prepared with relevant detail on the task at hand. Reliable, technically sharp, and genuinely invested in getting things right. If you want a developer who shows up, communicates clearly, and delivers, Sukumar is exactly that. I'd hire him again without hesitation! I am actively looking for the next project that I can bring him into. He is just that good.

Build MS Power Apps Timekeeping App
I gave the requirements to Sukumar for the project. However, they were never fully delivered, including after a month of back and forth. I finally gave up, and decided to go another route. WIll not be using the delivered product.
