- Write unit and integration tests; manage deployments through development, testing, and production environments following change-management and security protocols.
- Develop AI-driven automation using LLM APIs, agents, and scripted workflows for monitoring, onboarding, and support tasks.
- Maintain comprehensive technical documentation, runbooks, and handover notes.
- Participate in support rotations for client environments during US business hours.
