Meet Ivan
I help companies add AI to the systems they already run, without rewriting their core. 6+ years building banking and insurance software in Java; today I modernize legacy APIs at a major Brazilian bank. I built a document-based AI assistant (Azure OpenAI, RAG) for an energy company. Clear milestones and weekly written updates. Async-first, evenings and weekends (UTC-3).
