What I'm looking for

I am looking for a role that fosters innovation, collaboration, and growth, where I can leverage my technical skills to drive impactful projects.

With over 11 years of experience as a Staff Software Engineer, I have honed my skills in designing, developing, and deploying robust web applications. My expertise spans a wide range of backend technologies, including Python, Java, C#, and Golang, allowing me to build scalable, high-performance server-side solutions. I am equally adept in frontend development, utilizing JavaScript, TypeScript, and frameworks like Angular and Next.js to create dynamic, user-centric interfaces.

At Amazon, I designed and implemented a telehealth service that integrated AI-driven features and optimized data pipelines, significantly improving efficiency. My previous roles at Mercy and Zulily allowed me to lead migrations to modern frameworks and cloud infrastructures, enhancing performance and reducing operational costs. I am passionate about delivering innovative, maintainable code that drives business success through technical excellence.
