Bruno Kenji Okamoto · Software Development

I develop software
and keep learning
about artificial intelligence.

I am pursuing a degree in Systems Analysis and Development and have hands-on software quality experience. In academic projects, I have worked with C#/.NET MAUI, React, and PostgreSQL; I am currently expanding my knowledge of Java, Python, artificial intelligence, and cybersecurity.

Professional experience

Software quality
in practice.

PDVx Tecnologia

A cloud-based commercial automation platform for retail and food service.

Software Quality Intern

I validate PDVx across different devices and document product updates. When I find a problem, I investigate the conditions in which it occurs, share the evidence with the QA team and retest the fix to confirm the expected behavior.

  • Functional testingInstalling and validating the software on smartphones, tablets, computers, and smart terminals to verify compatibility and expected behavior.
  • InvestigationReproducing bugs across different scenarios and environments to identify the conditions that trigger them, including layout issues.
  • ValidationReporting evidence to the QA team, tracking fixes and retesting them to confirm the expected behavior.
  • DocumentationTechnical notes explaining new interfaces, fields, features and workflows step by step for support teams and customers.

Academic projects

Built
as a team.

FitShare and StudyFlow show my work across requirements, data modeling, development, documentation, and validation.

Aug — Dec 2025Presented at Acelera

FitShare

A mobile prototype focused on health and accessibility for older adults, people with disabilities, and people with lower fitness levels. I worked on the project from requirements analysis through user validation.

My contribution
Requirements, software engineering, prototyping, front-end, back-end, and documentation.
Engineering
Requirements analysis and UML class, use-case, and sequence diagrams.
Implementation
Built with C# and .NET MAUI, using in-memory data structures because the project did not allow a database.
Validation
Partnerships with Grupo Maior Idade and Studio Moving Saúde helped the team plan workouts and evaluate the prototype.
Outcome
Presented at the Acelera event at Fatec Cruzeiro; aligned with Sustainable Development Goals 3 and 10.

StudyFlow

A team-built study application with a web interface, a PostgreSQL database, and ESP32 integration. I worked on data modeling, the shared development environment, engineering documentation, and parts of the front-end.

Database
Conceptual and logical data models in BRMW (brModelo), followed by DDL and SQL code for PostgreSQL.
Environment
A Docker container with PostgreSQL ensured that the entire team used the same database version.
Engineering
Contributed to requirements analysis and created UML use-case and class diagrams.
Front-end
Implemented parts of the prototype with React.
