- Translated technical documents from English and French to Portuguese.
Project and Commercial Manager
Mectron
- Prospected a R$200,000 new contract for embedded software development from DCNS, a French Naval and Defense exporter, by working all the way from first cold contact with the client until the contract signature.
- Led engineers who were expatriated to France for software development on the client’s premises.
- Accumulated the responsibility for the contract prospected by me. Embedded software development for PLC under the PMI methodology to French clients.
- Reported my project progress to stakeholders, including the CEO, the new business director, and the French client DCNS.
- Finished the project within the deadline, and its profit was above expectations, from a loss to 10% positive.
- Wrote contracts, including pricing definitions and answers to requests for information and proposals (RFI/RFQ).
- Represented as an exhibitor in many international defense events, such as the Brazilian LAAD and IDEX in the United Arab Emirates.
Aerospace Engineer
Denel Dynamics
- Developed real-time data fusion for missiles and guided bombs: transfer alignment for initialization of inertial platform and aided navigation (GPS, BaroAltimeter, and aircraft INS).
- Validated the embedded code on hardware-in-the-loop simulation, embedded on ARM using C language, and analyzed flight test data by telemetry in the field at Air Force launching base.
- Increased the flight span duration from 1 to 10 minutes thanks to better navigation accuracy.
- Created a novel target tracking algorithm for missile employing extended Kalman filter by performing data fusion of passive target line-of-sight signals based on 6-states extended Kalman filter with design in MATLAB and embedded in C code.
- Automated code unit tests of in-house linear algebra and Kalman filter libraries.
- Simulated missiles subsystems including moving parts, hydraulic, external, and internal aerodynamics (subsonic and supersonic) on Simulink.
- Defined the technical specification of the inertial unit (gyroscope and accelerometer) for a long-range missile.
- Translated technical documents such as textbooks, papers, and technical reports from English to Portuguese.
Aerospace Engineer
Embraer
- Retrofitted the propulsion system for the F5-BR jet fighter and AMX (A-1M) jet bomber, including field tests with the airplane anchored to the ground and its turbine operating with afterburner on.
- Created a simulation of the Rolls-Royce Spey Mark 807 engine in MATLAB to support other departments such as aerodynamics.
- Managed propulsion system project requirements with DOORS software.

Brandify, Online Addition of Logo on Background of An Awesome Ad Image
This methodology is achievable by reusing a trained ResNet101 (transfer learning) for image segmentation, followed by image processing to find the best spot on the background to place the logo.
Virtual Try-on (Virtual Showroom, Augmented Reality with Real Garments)
Planned the scope of the proof-of-concept (POC) and minimum viable product (MVP) for a startup about to launch a new mobile shopping experience by combining augmented reality, photogrammetry, artificial intelligence, simulations, and virtual try-on.
The outputs are a photorealistic image of the user wearing the virtual garment and a heatmap as a realistic representation of how the garment will fit and the proper size for the specific user.
Proposed new state-of-the-art solutions (better than photogrammetry) to accurately scan the human body.
