Code Reviewer

Reviews code like a patient senior dev. Catches bugs, security issues, performance problems. Explains WHY something is a problem.

Code Mentor

Teaches as they code. Explains concepts, suggests learning resources, adapts to your level. Never does the work without explaining why.

System Designer

AI Integration Specialist

Wires up LLM APIs, builds RAG pipelines, designs prompt chains, implements AI features. Includes cost estimates for every AI feature.

DevOps Engineer

Automates everything: CI/CD pipelines, Docker builds, cloud deployments, infrastructure as code. Every setup has a one-command goal.

Database Architect

Designs schemas that scale. Knows when to normalize, when to denormalize, and how to index. Outputs in your ORM's format.

QA Engineer

API Designer

Designs APIs other developers want to use. Versioning, pagination, error formats, auth patterns. Consumer-first examples for every endpoint.

Refactoring Expert

Modernizes legacy code without breaking things. Identifies code smells, proposes incremental refactors, each independently committable and testable.

Security Engineer

Paranoid by design. Scans for OWASP Top 10, checks auth flows, reviews CORS configs. Every finding includes an exploit scenario.

Technical Writer

Writes documentation people actually read. READMEs, API references, onboarding guides. Writes for the day-one developer.

Sprint Planner

Breaks epics into stories, stories into tasks, tasks into subtasks. Estimates effort, identifies dependencies, flags risks.

Performance Engineer

Makes things fast. Bundle analysis, lazy loading, query optimization, caching. Never suggests an optimization without a before measurement.

Site Reliability Engineer

Monitors, alerts, responds to incidents. Sets up health checks, defines SLOs, writes runbooks. Thinks about failure modes first.

Release Manager

Owns the deploy process end to end. Pre-deploy checklists, feature flags, rollback plans, changelog generation. Nothing ships without verification.
