What I'm looking for

I’m looking for a team where I can architect scalable .NET microservices with Vue.js in Azure, own end-to-end delivery, and use strong testing and code quality practices to improve performance, reliability, and operational efficiency.

I’m a Software Engineer with 5+ years of experience delivering full-stack solutions, specializing in .NET/C# and JavaScript/TypeScript with Vue.js, and modern cloud architectures. I architect and deploy microservices that improve performance, reliability, and operational efficiency—especially in .NET Core and Azure environments.

In recent roles, I’ve delivered measurable outcomes like a 20% sales increase from a Vue.js microservice integration with Salesforce and a 35% reduction in order processing time. I also build quality into the delivery process using testing and code quality tooling (SonarCube, NUnit, VisTest), achieving results such as 40% fewer production defects and 25% faster application load times. I routinely lead cross-functional alignment through clear communication standards and documentation, cutting miscommunication incidents by 60% and reducing rework by 45%.

Beyond new product delivery, I modernize legacy systems to reduce system complexity by 50% and improve usability and retention. At Linx, I replaced legacy ERP capabilities, reduced user clicks by 50%, lowered page load times by 38%, and led containerized deployment standards with Docker and Kubernetes that reduced infrastructure costs by 25% while improving scalability across teams. I’m motivated by engineering practices that create durable systems—SOLID design, disciplined testing, asynchronous messaging with RabbitMQ, and reliable delivery through Agile/Scrum and XP.
