Hello world,
And I'm a Software Developer, an AI Engineer and a Content Creator
Name: Isis Beatriz de Alencastro
Location: Porto Alegre, Brazil
Education: Computer Science (in progress)
I am a software developer and AI Engineer focused on applied AI: putting language models inside systems that actually run in production.
I integrate LLMs (GPT-4 and Claude) with channels like WhatsApp Business, maintain PostgreSQL backends with vector semantic search (RAG) and build n8n automations that connect the database, the model and the channel. I also build websites and web applications in React, TypeScript and Python.
I am a Computer Science student at UniRitter, the founder of my own technology studio, and I create content about my journey on LinkedIn and YouTube. I work with organization, care for data and testing before shipping: nothing goes live without someone checking what was delivered.
My studio
IBA is my development, AI and automation studio in Porto Alegre, Brazil. We put AI to work in companies' day-to-day operations: customer service that answers after hours, reports that put themselves together without anyone copying spreadsheets, and tools that pass information to one another.
Websites, portals and systems that grow with your operation. An institutional website live in up to 10 business days; custom portals and systems with the scope agreed in writing.
