Systems that deliver.
Based in Campinas, Brazil, I am a Mechanical Engineer with 18+ years of experience across hydraulic turbine systems, industrial equipment, pressure vessels, fabrication drawings, technical documentation, supplier support, and global engineering workflows.
My work sits at the intersection of mechanical engineering and digital systems: ASME-based calculation logic, 3D-driven documentation, structured review workflows, engineering databases, and AI-assisted tools that improve speed, traceability, and execution quality.
I do not see engineering as isolated drawings or calculations. I see it as a system of decisions, documents, checks, interfaces, and feedback loops. When a process is repetitive, unclear, or error-prone, I look for a way to structure it, standardize it, and automate it.
Mechanical Design
ASME-based vessel design, fabrication drawings, internals, nozzles, calculations — from concept to manufacturing support.
Digital Engineering
Web apps, AI-assisted review workflows, automation pipelines built to eliminate recurring, manual engineering bottlenecks.
Process Improvement
3× faster drawing delivery via 3D-driven workflows, standard templates, and structured documentation systems.

Mechanical Engineer II — Global Process Engineering
Pall Corporation — Diadema, SP, Brazil
- 01Delivered full mechanical engineering packages for industrial filtration & pressure vessel projects — 3D models, fabrication drawings, calculations, BOMs.
- 02Completed complex vessel drawings in ~18 hrs using a 3D-driven workflow, compared with an internal estimate of ~60 hrs using a traditional 2D process.
- 03Proposed a flange recovery solution that reduced estimated cost and schedule impact while avoiding unnecessary replacement parts.
- 04Created Active Drainage Filter / RCR2 layout sketches clarifying vessel height & internal configuration options for cross-functional stakeholders.
- 05Developed PULSE / GPE Tracker, Engineering Comments Intelligence & CRS Automation, TBE Quality Gate, and PV Design Reference Database concepts.
- 06Built lightweight standard-work templates for Drawing Review, 1st Check, TBE, CRS, and Weekly Project Review.
Digital engineering work built outside the day job.
