Octree-based Approach for Real-time Visualization of Surfaces Defined by Signed Distance Fields (B.Sc. thesis)

Efficient solution for the estimation of surfaces of triangle-based objects through the use of signed distance functions. The solution is based on an octree data structure, which acts as a recipient to store and manage distance values of a given object. It works for any closed triangle mesh, and allows real-time visualization of operations such as the offset, the union, and the intersection.

Logon Renderer (personal project)

Logon Renderer is a project started on the Physically Based Rendering course, offered by Dr. Christian Pagot, at Universidade Federal da Paraíba. The application is a physically based renderer, based on the Path Tracing algorithm, that has been written from scratch in C++ for educational purposes. Although some acceleration techniques have already been (and may be in the future) included into the project, the main goal is not performance, but the construction of a high quality, full featured, CPU-based ray tracer through readable, modular, extensible and easy to understand code.

Machine Learning Intern

Ericsson

• Designed and developed hardware resource forecaster for network infrastructure. Containerized solution uses statistical and deep-learning methods trained on existing logged usage data. Allows on-demand probability forecast suiting diverse use-cases.
• Lead the development of smart search engine for network defects. Containerized API and interface allows engineers to quickly find previously logged solutions of similar defects across Ericsson global. Uses combination of existing search algorithms and trained NLP models for enhanced suggestions. Validated and approved by network engineers.
