Reinaldo Junior
@reinaldojunior
Full-stack software engineer delivering secure, regulatory-compliant React and ASP.NET Core products.
CanadaWhat I'm looking for
I’m a Full Stack Software Engineer with 10+ years building and shipping React and ASP.NET Core applications across legal-tech, fintech, and enterprise domains that demand security and regulatory rigor. I design microservices and RESTful APIs, and I partner with stakeholders to shape technical roadmaps.
In recent work, I build enterprise justice management features with React and C# .NET Core, integrating with SQL Server and Microsoft Dataverse. I gather requirements directly from legal-sector stakeholders and translate them into well-defined, dependency-mapped technical tasks, shipping in Agile/Scrum sprints.
As a freelance developer, I designed a government data search platform with a NestJS backend exposing REST APIs over PostgreSQL, and I delivered MaidPlanner end-to-end with a React + React Native frontend, a C# .NET Core REST API, and Stripe payment integration. I architected AWS and GCP infrastructure, automated deployments with GitHub Actions, and enforced test suites as a CI gate.
Earlier roles as a Senior Full Stack Developer pushed me deeper into performance, security hardening, and clean-code practices—optimizing SQL queries, mentoring developers through code review as a quality gate, and building record-control and sector-management systems. I’m at my best when fast delivery and compliance can move together.
