What I'm looking for

I seek senior engineering roles where I can lead scalable web/API projects, mentor teams, use data-driven development, and improve CI/CD and reliability.

I am a senior software engineer with 10 years of experience building scalable web and mobile applications, skilled in full-stack development, API architecture, and cloud-native tooling. I excel at collaborating with product and design teams to deliver user-centric features, driving improvements through data-driven decisions and automated testing.

Throughout my career I have led cross-functional teams, mentored junior engineers, and helped shape architectural decisions to increase system scalability and reliability. I actively promote best practices—CI/CD, code reviews, and agile methodologies—to raise code quality and accelerate delivery.
