At ISESMT, I develop three SaaS systems for occupational health and safety, working across frontend and backend. On Avalia NR17, I restructured the ergonomic assessment PDF to meet ABNT standards and cut the opening time for a 138-page report from 150 seconds to 40.
I implemented report versioning, a 5W2H action plan, mobile field data collection with autosave, and an indicators dashboard. I also brought ergonomic calculations to the server and created browser-based posture measurement from photos and video using MediaPipe.
Across these systems, I addressed customer data-isolation vulnerabilities and expanded automated tests for that area from 35 to about 220 cases. I also worked on payment integrations, audit trails, PDF reports, and responsive interface redesigns.
On the UFPI projects PREMAUT and TB-Koch, I develop web and mobile applications, APIs, and user interfaces. I’m also developing a thesis project that analyzes activities and handwriting for possible signs of dyslexia, using OCR, text processing, and predictive models.
