Build and own the backend service for our AI Agent - a TypeScript/Node application that operates inside Google Chat and integrates with external system.

Develop the Google Chat app: event receiver, messages, file handling, mentions, interactive cards/buttons, and agent-initiated messages.

Implement identity and access control- matching each user and enforcing role-based permissions so the agent never has more rights than the person it acts for.

Build the integration through the MCP server (Agents SDK MCP client over streamable HTTP), with request keys, approval checks, chatter logging, and all-or-nothing writes; no direct database writes.

Develop the planning and allocation engine in plain TypeScript - exact, repeatable calculations for capacity, workload, hour estimates, and monthly planning.

Implement scheduled and background jobs with pg-boss on PostgreSQL (reminders, daily checks, reports) that are idempotent and survive restarts.

Design the PostgreSQL 16 + pgvector schema and build the activity log (end-to-end tracking IDs), retries/back-off, and PM safety controls (pause any feature; correct rather than delete).

Own deployment and operations on a lean stack: DigitalOcean/Ubuntu, systemd, Nginx, Let’s Encrypt, and Bitbucket Pipelines CI/CD, keeping the service running reliably 24×7.
