Building production software for industrial companies — Java/Spring and Python backends, Angular/React frontends, AWS deployment, and applied AI at the core.
I'm a software engineer with 25+ years of experience designing and building production systems — from IBM mainframe manufacturing in Brazil and the United States to cloud applications and applied AI in Germany.
At WEISS GmbH I built the backend of the product configurator that is live on the company's website and used daily by customers and the sales team. I work across Java/Spring, Python (Flask, FastAPI), Angular and React; I deploy to AWS and Heroku with Docker and CI/CD; and I build practical AI systems with LangChain — RAG pipelines, LLM fine-tuning for text and images. My focus is software that an organisation actually depends on, not demos. I started in manufacturing and test engineering of IBM mainframes, where precision and quality at scale were non-negotiable — and I bring that same systems rigour to every line of code I ship.
Production-proven across backend, frontend, cloud, and AI layers.
