01About

Engineering depth.
Digital execution.
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.

02Drawings

Fabrication-ready drawings.
Built precisely.

Engineering drawings are where design intent becomes manufacturing reality. I produce fabrication-ready documentation for pressure vessels and industrial equipment, with clear dimensions, weld details, BOM structure, notes, interfaces, and review logic to support suppliers, quality teams, and project execution.
3D Modeling - Inventor & SolidWorks
Parametric 3D models developed for equipment design, fabrication planning, interference checks, assembly validation and technical documentation. Models can be delivered in native CAD formats or exported as STEP, IGES or other neutral formats when required.
2D Fabrication Drawings — AutoCAD, Inventor & SolidWorks
Manufacturing-oriented 2D drawings created from 3D models, including views, sections, dimensions, material references, technical notes and details needed for supplier quotation, fabrication, inspection and customer approval.

From Engineering Desk to Field Reality

My engineering experience goes beyond calculations, CAD models and technical documentation. I have worked closely with real equipment, suppliers, fabrication shops, industrial plants and offshore environments, supporting practical decisions where design intent must meet access, assembly, maintenance, safety and manufacturing constraints.

This hands-on background helps me create drawings, models and engineering documents that are not only technically correct, but also easier to fabricate, inspect, install and maintain.

Good engineering is not only what fits on the drawing. It is what can be fabricated, installed, inspected, maintained and trusted in real operation.
Hands-on Experience
Direct involvement with equipment, inspection, installation and maintenance activities.
Real World Understanding
Practical knowledge of piping, equipment, access, constraints and operational conditions.
Better Engineering Deliverables
Documentation and designs that work in the shop, in the field and throughout the asset life.
Industrial & Offshore Exposure
Experience in offshore and heavy industrial environments with a focus on safety and reliability.
