What I'm looking for

I am looking for a role that fosters innovation, encourages collaboration, and offers opportunities for professional growth.

As a Senior Software Engineer with over a decade of experience, I have a proven track record of leveraging cutting-edge technologies to architect scalable, secure, and real-time solutions. My journey began at Columbia University, where I earned my Bachelor's Degree in Computer Science, and has since evolved into a passion for enhancing user experiences through innovative software development.

At SimplePractice, I designed and implemented a telehealth service that significantly reduced patient wait times by 40% through AI-driven features. My expertise in backend and microservices has allowed me to build robust systems using Java, Node.js, and AWS, while my frontend contributions with React and Next.js have ensured a seamless user experience for over 64,000 active users. I thrive on mentoring my team and fostering a culture of continuous learning and improvement.

Previously, at Expedia Group, I enhanced platform scalability and stability during peak business periods by developing resilient microservices and optimizing data storage solutions. My commitment to quality and performance has consistently resulted in improved user engagement and satisfaction. I am excited to bring my skills in software engineering, cloud technologies, and AI to new challenges.
