What I'm looking for

I’m looking for a team where I can build and optimize REST APIs and SaaS features using .NET and modern frontend frameworks, working in Agile/Scrum/SAFe with CI/CD, unit testing, and code reviews to deliver measurable performance and user impact.

I’m a Full Stack Software Engineer with 3 years of experience building and optimizing RESTful APIs and enterprise SaaS platforms. I specialize in C#/.NET 8, Vue.js/React, and SQL/NoSQL databases, and I’ve delivered client-facing features within Agile/Scrum teams.

I’ve consistently improved backend performance by 30–50%, shipped modular backend systems using SOLID principles and repository/service patterns, and reduced code redundancy by 25%. From tuning SQL/LINQ to scaling PostgreSQL schemas for growing transaction volume, I focus on maintainability, performance, and clear API contracts supported by documentation and diagramming.
