    I’m a full-stack developer with 7 years of experience, specializing in designing and optimizing scalable, performance-oriented applications. I have a strong understanding of software design patterns (e.g. Singleton, Factory), RESTful, and GraphQL API designs, which I frequently use in my work experiences. I am also open to working on a project in microservices architecture. My skills include performance optimization and enhancement for code and databases, advanced debugging and logging tools. I can say that I tested my developments in relatively basic ways, as the teams I was in did not include testing in their development programs. However, I am open to working with teams that tested frameworks in ideal ways (unit, integration, performance) and used security best practices (OWASP, secure coding). Although not in a primary role, I was involved in scaling applications and implementing CI/CD pipelines on the Azure cloud platform. I also have extensive experience in Git, GitFlow, and Agile project management tools like Azure DevOps Boards, JIRA. I'm trying to improve myself and gain as much experience as I can in different technologies. When I'm not working, I spend time with my family and friends. I am interested in team sports, such as 3x3 basketball and football, and individual sports, such as swimming, cycling, and running. I also enjoy camping and fishing.
