Participate in design walkthroughs, code reviews, estimation, sprint planning, and release planning.

Analyze and troubleshoot technical issues arising across development, deployment, migration, and production environments.

Collaborate with business analysts, architects, UX designers, testers, DevOps engineers, and security teams across the full software lifecycle.

Prepare comprehensive technical, deployment, system, and user documentation.
