I specialize in Python automation, SQL, Oracle Database, and PL/SQL, with a strong focus on performance optimization, query tuning, data validation, and data migration. My work has centered on turning manual, support-intensive, and validation-heavy processes into reliable automated workflows that improve delivery speed, reduce operational effort, and increase software reliability. I have experience working across enterprise systems, internal tools, legacy modernization, REST API integration, and technical documentation, and I enjoy solving complex problems through root-cause analysis and engineering discipline. I have also collaborated closely with QA, support, product, and technical leadership to investigate production issues, validate business scenarios, and reduce delivery risk. I am based in Brazil and am open to remote LATAM opportunities. I value measurable impact, technical ownership, mentoring, and continuous improvement in engineering teams. ## Skills ### [Python](https://jobicy.com/talent/python.md)[SQL](https://jobicy.com/talent/sql.md)[Communication](https://jobicy.com/talent/communication.md)[JavaScript](https://jobicy.com/talent/javascript.md)[Collaboration](https://jobicy.com/talent/collaboration.md)[React](https://jobicy.com/talent/react.md)[Jira](https://jobicy.com/talent/jira.md)[Git](https://jobicy.com/talent/git.md)[Troubleshooting](https://jobicy.com/talent/troubleshooting.md)[PostgreSQL](https://jobicy.com/talent/postgresql.md)[Mentoring](https://jobicy.com/talent/mentoring.md)[MongoDB](https://jobicy.com/talent/mongodb.md)[PHP](https://jobicy.com/talent/php.md)[Technical Documentation](https://jobicy.com/talent/technical-documentation.md)[REST APIs](https://jobicy.com/talent/rest-apis.md)[PowerShell](https://jobicy.com/talent/powershell.md)[Azure DevOps](https://jobicy.com/talent/azure-devops.md)[Vue.Js](https://jobicy.com/talent/vue-js.md)[Root Cause Analysis](https://jobicy.com/talent/root-cause-analysis.md)[System Integration](https://jobicy.com/talent/system-integration.md)[Data Migration](https://jobicy.com/talent/data-migration.md)[Data Validation](https://jobicy.com/talent/data-validation.md)[Bitbucket](https://jobicy.com/talent/bitbucket.md)[Workflow Automation](https://jobicy.com/talent/workflow-automation.md)[Pl SQL](https://jobicy.com/talent/pl-sql.md)[Laravel](https://jobicy.com/talent/laravel.md)[Query Optimization](https://jobicy.com/talent/query-optimization.md)[ERP Software](https://jobicy.com/talent/erp-software.md)[Enterprise Software Development](https://jobicy.com/talent/enterprise-software-development.md)[C#](https://jobicy.com/talent/c-sharp.md)[WSL](https://jobicy.com/talent/wsl.md)[DBeaver](https://jobicy.com/talent/dbeaver.md)[Firebird](https://jobicy.com/talent/firebird.md) ## Tech Stack & Tools ### Collaboration [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/jira/jira-original.svg) Jira](https://jobicy.com/talent?tool=jira.md) ### Data Stores [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/dbeaver/dbeaver-original.svg) DBeaver](https://jobicy.com/talent?tool=dbeaver.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/firebird/firebird-original.svg) Firebird SQL](https://jobicy.com/talent?tool=firebird.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/mongodb/mongodb-original.svg) MongoDB](https://jobicy.com/talent?tool=mongodb.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/postgresql/postgresql-original.svg) PostgreSQL](https://jobicy.com/talent?tool=postgresql.md) ### Development [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/bitbucket/bitbucket-original.svg) Bitbucket](https://jobicy.com/talent?tool=bitbucket.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/git/git-original.svg) Git](https://jobicy.com/talent?tool=git.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/github/github-original.svg) GitHub](https://jobicy.com/talent?tool=github.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/powershell/powershell-original.svg) PowerShell](https://jobicy.com/talent?tool=powershell.md) ### Languages & Frameworks [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/delphi/delphi-original.svg) Delphi](https://jobicy.com/talent?tool=delphi.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/laravel/laravel-original.svg) Laravel](https://jobicy.com/talent?tool=laravel.md) [![Image](https://cdn.jsdelivr.net/gh/devicons/devicon@master/icons/react/react-original.svg) React](https://jobicy.com/talent?tool=react.md) ## Experience Software Engineer - Enterprise Systems @ TOTVS S/A Jun 2024 - Present Develop and maintain business-critical ERP workflows for sales, pricing, order processing, validations, and enterprise operations using Delphi, Oracle Database, PL/SQL, SQL, REST APIs, and internal tools.
