Leonardo Alves Guimaraes 📍 Sao Paulo - SP
I'm a full stack developer. I like to build entire systems from scratch at once, and I do everything myself, from the background application interface to the user interface. I am currently working on the event ticketing platform Evianto and am personally responsible for most of the technology stack, including the user site, admin panel, background application interface and even the AI-powered WhatsApp chatbot.
While I'm still at IFSP, I spend my free time experimenting with new tools and honing my existing skills.

I've been doing 3D modeling and printing for some time now, and I usually like to make practical custom parts myself. I do parametric modeling with OpenCAD and create organic shapes and art-style models with Blender. I'm very familiar with G code, and I write it myself, read it and fine-tune the speed, the quality and the behavior of the material. I also built the FarmLoop Stage 2 on the Bambu Lab A1 Mini using a Raspberry Pi Pico and designed and built the case and mechanical parts myself. I have worked with a variety of filaments, including PLA, PETG and TPU, and I have a complete understanding of how to adjust each material. Even if the STL file gets corrupted, it can be repaired, and the results can change dramatically with a few changes to the slicing settings.
Right now, I'm focusing on Evianto. Interactive seating tables for transaction sales, Mercado Pago payments, multi-agent AI chatbots for WhatsApp, admin dashboards for transaction and customer management, CI/CD pipes using Jenkins and much more.
