Message

At Tecnomotum, I developed secure microservices and REST APIs using clean architecture, JWT, and OAuth2. I also worked on containerized services on Google Cloud Run and optimized SQL queries for performance and KPIs.

I built ETL pipelines to BigQuery and data-cleaning pipelines for LLM training and fine-tuning. Earlier, I worked on REST APIs and SOAP services at Tecnomotum, and microservices, Angular integrations, and Jenkins CI/CD pipelines at Bizlink.
