Educational AI - Student Assistance

Educational AI - Student Assistance

Distance learning brought many benefits, but also a big challenge: the lack of direct contact with the teacher, which can delay answering questions and grading activities.

I participated in building the infrastructure of an educational AI designed to support students in a personalized and efficient way.

WhatsApp CRM Web Extension

WhatsApp CRM Web Extension

I built a solution to integrate an educational institution's CRM with WhatsApp Web, bringing service and automation together in a single workflow.

With features like reminders, a customizable image editor, real-time notifications, scheduled messages and follow-ups, the solution has driven millions in results since November 2024.

RBot.com.br

RBot.com.br

A proprietary SaaS that uses multiple LLM models to generate humanized messages for mass WhatsApp outreach, distributing sends across 50+ simultaneous chips.

It includes documented integrations with external systems and vector knowledge in its responses, ensuring high-quality replies. The solution directly drove lead generation and reached a 2,650% ROI, considering only platform costs.

Student Portal

Student Portal

I participated in building a student portal from scratch, centralizing the entire academic journey: from enrollment to certificate issuance.

Built with my own front-end and back-end, from design to deployment.

About Me

I'm a full stack developer, pragmatic and results-driven, with experience in large-scale projects across the healthcare and education sectors.

For over 4 years I've worked as a Full Stack Developer at a higher education institution. I participated in building educational portals, an AI agent, the main sales landing page and 4 other websites. I'm also responsible for several reports within the management system.

My approach combines solid engineering practices with continuous delivery. Currently, I focus on integrating Artificial Intelligence and automation to optimize products.
