Portfolio Projects and Capstone Roadmap

Project A — Developer Assistant

Capabilities: Repository metadata, documentation search, and issue lookup.

Architecture: Read-only tools + documentation resources + reusable review prompt.

Tests: Invalid paths, missing repository, pagination, and untrusted document injection.

Interview story: Explain why source reads are resources while searches with filters are tools.

Project B — Business Data Assistant

Capabilities: Customer/order lookup, validated filters, and role-based access.

Architecture: MCP adapter → service → authorization policy → repository.

Tests: Cross-customer denial, parameterized queries, timeouts, empty results, and pagination.

Project C — Support Assistant

Capabilities: Ticket lookup, draft creation, approved submission, and an audit log.

Safety: Separate read/write tools; writes require a preview, confirmation, and an idempotency key.

Final capstone

Build two servers and one custom host: a documentation server + a business server + a TypeScript client. Add tracing, an approval UI, failure recovery, deployment, a threat model, architecture decision records (ADRs), tests, a README, and a short demo.

Resume bullet template

“Built a TypeScript MCP system exposing validated tools and resources over stdio/Streamable HTTP, with role-based authorization, approval-gated writes, structured outputs, integration tests, and operational tracing.”

Use only the features you have actually completed and measured.
