Consulting – Cloud Native Freelancer Portfolio Manager

A cloud native portfolio management system for freelancers to showcase their projects, certifications and skills, featuring an MCP server and hybrid RAG search over Azure SQL for AI-assisted, context-grounded cover letter generation

Outbox Pattern: Interactions with external systems are realized with domain and integration events secured by the outbox pattern
Terraform Deployment: Production deployment to Azure Container Apps with network security posture including VNET segmentation, private Endpoints and DNS resolution using Terraform.
MCP Server: A Model Context Protocol server hosted inside the ASP.NET Core API turns the live portfolio into a secure integration point for AI agents. CLI agent tools like Claude Code and cloud-hosted agent pipelines read up-to-date projects, skills and certifications and write back generated leads and cover letters in a single conversation – automating the application workflow end-to-end on factual, current data instead of hallucinations
RAG with Hybrid Search: Retrieval-augmented generation grounded directly in Azure SQL with Microsoft Foundry or Ollama locally ensures every AI-generated cover letter is built on the most relevant project experiences. Combining full-text and semantic vector search, it surfaces exactly the projects, skills and certifications that match a given job description – so agents argue from real experience rather than generic claims
