Deployment & Operations Expert responsible for securely, rollbackable, and observably deploying builds that pass Reviewer and QA gates to servers (PM2 3-process cluster + Nginx reverse proxy + BT Panel). Adheres to engineering baselines including zero-downtime deployment, health checks, rollback within ≤3 minutes, and post-release smoke testing. Handles deployment orchestration, configuration management, traffic management, and monitoring & alerting. Applicable when receiving task cards from the Deploy department or needing to release to production.
Create safe, reversible database migration scripts with rollback capabilities, data validation, and zero-downtime deployments. Use when changing database schemas, migrating data between systems, or performing large-scale data transformations.
Generate comprehensive rollout plans with preflight checks, step-by-step deployment, verification signals, rollback procedures, and communication plans for infrastructure and application changes
Execute database migrations across ORMs and platforms with zero-downtime strategies, data transformation, and rollback procedures. Use when migrating databases, changing schemas, performing data transformations, or implementing zero-downtime deployment strategies.
Deployment procedures and CI/CD pipeline configuration for Python/React projects. Use when deploying to staging or production, creating CI/CD pipelines with GitHub Actions, troubleshooting deployment failures, or planning rollbacks. Covers pipeline stages (build/test/staging/production), environment promotion, pre-deployment validation, health checks, canary deployment, rollback procedures, and GitHub Actions workflows. Does NOT cover Docker image building (use docker-best-practices) or incident response (use incident-response).
Produces Go/No-Go deployment checklists with SQL verification queries, rollback procedures, and monitoring plans. Use when PRs touch production data, migrations, or risky data changes.
Database migration best practices — schema changes, zero-downtime migrations, rollback strategies, and data migration patterns. Reference when modifying database schemas.
Orchestrating migrations, upgrades, and modernization across frameworks, libraries, APIs, databases, native runtimes, and dependencies. Detects deprecated libraries, suggests native API replacements, runs technology radar, generates codemods, applies incremental strategies (Strangler Fig/Branch by Abstraction), verifies behavioral equivalence, and produces rollback plans.
Land a subagent worktree branch onto the integration branch with preflight + recorded rollback. Triggers: HSM `merge-pending` substate, `merge_orchestrate` next_action verb. Local git operation — NOT remote PR merging (that is `merge_pr` in the synthesize phase).
Manage database migrations and schema versioning. Use when planning migrations, version control, rollback strategies, or data transformations in PostgreSQL and MySQL.
Transaction correctness audit worker (L3). Checks missing intermediate commits, transaction scope (too wide/narrow), missing rollback handling, long-held transactions, trigger/notify interaction. Returns findings with severity, location, effort, recommendations.
Manage project state using append-only, time-based Markdown files under /project/. Use when managing multi-epic projects, tracking decisions over time, maintaining audit trails, coordinating distributed teams, or requiring rollback visibility. Forces context loading, explicit confirmation gates, and immutable history preservation.
