• Update and maintain internal documentation, API specs, and runbooks

• Join sprint planning, daily standups, and retrospectives as an active team member

• Experiment with frontend components in the internal tooling dashboard (React + TypeScript)

• Production TypeScript microservices — structure, patterns, and testing

• Event-driven architecture with Kafka and RabbitMQ

• Docker and basic Kubernetes concepts (deployment, logs, exec)

• Code review culture and engineering standards in a global product company
