Provide technical reviews of requirements, organize them, and estimate the time required for development.
Integrate these applications within the BTS communications network.
Collaborate with multidisciplinary teams to design, develop, and maintain high-availability and high-performance applications.
Troubleshoot and debug applications to ensure their correct functioning.
Participate in code reviews and share technical criteria with the team.
Work with AI-assisted development tools (Claude Code): agents, skills, and automated workflows.
Occasional collaboration on the frontend (Angular) when the project requires it.
