He has strong problem-solving skills and is motivated by delivering value and finding new ways to optimize and simplify designs, clean code, and clean architecture.
Understanding, explaining, and enforcing the software architecture approach for software companies.
Overseeing the design, development, and deployment of software solutions.
Ensuring that high-level decision-making is used to manage the software development process.
Creating architectural flows for new features with scalability and flexibility in mind.
Writing code in Kotlin with Spring Boot and using Kotest and MockK for unit and integration testing.
Working with databases such as Neo4j, MongoDB, and PostgreSQL.
Developed a Java SDK API for Health Canada PrescribeIT to be used as a helper for the API access and to simplify the workflow required to have external systems integrated with the government system.
Built the architecture and configured the environment to assist developers in meeting the requirements.
Assisted the project manager in developing a roadmap, CI/CD, and a Jira workflow for milestone releases.
Built a static code analyzer product that takes advantage of microservices architecture to evaluate thousands of repositories and commits per day, using Spring Boot, AWS SQS/SNS, and Kubernetes to build microservices and an API façade for conventional version control systems like Git and Mercurial, with some connections with GitHub API, Jira, FogBugz, and Auth0.
Implemented Apache Airflow to orchestrate DAG (Directed Acyclic Graph) on Kubernetes cluster and built Cypher Queries to catch code violations in a Neo4j database with AST for the corresponding programming language; used Angular 8 and RxJS to create a Spring Shell command-line application that integrated the REST API and a web UI interface.
Followed quality practices, clean code, and architecture principles, with all code passing two or more code review phases before being merged into milestone/master branches and unit tests covering 100% of the new lines introduced.
Created two web portals for Brazil IRS: SICOBE (Sistema de Controle de Bebidas) and SCORPIOS (Sistema de Controle e Rastreamento da Produção de Cigarros).
Built several stored procedures and batch operations while working on front-end and back-end projects, using a Scrum approach with daily meetings, sprint planning, and Jira tool management.
Involved in creating systems used by all cigarette and beverage producers in Brazil for IRS tax auditing, handling ~40 billion items per year in manufacturing.
Managed the environment adequacy and development processes for the team's developers.
Performed system migration from Visual Basic to Java and system development for business proposal verification.
Improved project on processes and systems for operational and billing areas.
Focused on futures, shares, and asset custody and maintained the bank website.
Managed requirement gathering and improvement of proposals for company systems, including refactoring of Java code.
Migrated a project from legacy JBuilder to IDE Eclipse.
Developed a static code analyzer that processes thousands of repositories daily.
Utilized Spring Boot, AWS SQS/SNS, and Kubernetes to build microservices and an API façade.
Integrated Apache Airflow for DAG orchestration on a Kubernetes cluster and Cypher Queries for code analysis in a Neo4j database.
Qohash is a platform for finding, tracking, and safeguarding sensitive data.
The Qostodian platform deploys in minutes to identify risks and track data propagation.
It utilizes Kotlin, Spring Boot, and testing frameworks for architecture and persistence.
Developing a Java SDK API, PrescribeIT, for API access and system interface.
Utilizes Core Java, Jackson, Apache HttpClient, Cucumber, JUnit, and other libraries.
The project aims to simplify the process of connecting external systems with the governmental system.
