English instructor at SENA using Claude and Claude Code to build offline AI workshops, grading tools, and teacher training workflows.

Message

At SENA – National Vocational Training Service, I design CLIL and task-based English lessons for young adults training for software development and digital animation jobs. I introduced voice-based custom GPTs as speaking partners for about 60 learners and used survey feedback to inform the next design.

For teachers and educators, I’ve created training materials, playbooks, and guides, and delivered more than 160 hours of AI training on lesson planning, assessment, and feedback. In the CILE Program, I produced 14 methodological guides with 70 annexes, a bank of 87 teaching resources, and eight implementation plans.

With Claude Code, I’ve built tools including an offline AI tutor, the SET placement test and exam simulator, Engrama, and a phone-photo paper exam grader. I also built and optimized a family travel agency website for AI search visibility, which brought in more than 30 international quote requests in its first month.
