Deploy applications through CI/CD pipelines and partner with DevOps teams to support scalability, monitoring, and production readiness.

Troubleshoot and resolve complex issues across the application stack.

Conduct code reviews and contribute to continuous improvement of engineering practices.

Mentor and support junior developers across frontend, backend, and integration work.

Proficiency with modern front-end frameworks (e.g., React with Context API and Hooks).

Experience with geospatial technologies such as ESRI, PostGIS, and Mapbox.

Demonstrated ability to diagnose and solve complex technical problems.

Strong communication and collaboration skills, with the ability to explain technical concepts clearly.

Experience designing or contributing to agentic systems, including multi step or multi agent workflows.

Knowledge of CI/CD pipelines and automated deployment practices.
Familiarity with Google Cloud Platform (GCP).
Experience building AI‑driven or agent‑based applications in production.
Hands‑on experience with multi‑agent orchestration, Model Context Protocol (MCP), and standardized agent access to local and remote data.
