Vignesh Athiappan · Senior Technical Lead

Enterprise systems, rebuilt for the AI era.

Architect, builder, and team lead — 7+ years of experience. I take estates from legacy to cloud-native — then put agents, models and MCP servers to work inside them. Designed, shipped and run in production.

What I do
Applied AI — front and centre

Agents, models and MCP servers — in daily use, not in demos

  • A multi-agent enterprise assistant on Microsoft Teams, org-wide
  • Azure AI Foundry models deployed into day-to-day work, per application
  • Data agents on the lakehouse · agents for talent acquisition
  • Multiple MCP servers turning systems of record into safe AI tools
  • A knowledge graph grounding it all · Foundry IQ and Fabric IQ next
The AI work, in full →
01 · Platform

Modernize

  • A decade-old layered architecture — migrated to Azure, entirely
  • Legacy SQL purged and tuned to a fraction of its size
  • A microservices application framework, end to end
More →
02 · Integration

Connect

  • REST APIs enabled across the whole application estate
  • Service Bus for resilience · API Management as the gateway
  • Logic Apps and Functions stitching systems together
More →
03 · Security

Secure

  • Front Door and WAF at the edge, private VNets within
  • Black-, grey- and white-box angles per application
  • Monitoring and alerts wired to act, not decorate
More →
04 · Observability

Observe

  • App Insights and Log Analytics across every layer
  • One correlated trace, from the user to the last hop
  • Load, capacity and cost measured, not argued
More →
05 · Data

Ground

  • Microsoft Fabric lakehouse — architecture designed end to end
  • Security built into the data layer, not bolted on
  • Dashboards leadership actually opens
More →
06 · Delivery

Ship

  • Business platforms delivered in weeks, adopted org-wide
  • An EU rollout led on the ground, thousands onboarded
  • A multi-disciplinary team across platform, data, AI and QA
