Software Engineer
Apple
Jan 2022 - Nov 2025 • 3 yrs 10 mos
Worked as a Software Engineer at Apple, where I focused on improving Apple Pay, specifically around payment reliability and checkout issues. I worked on identifying bugs that could interrupt the payment process, improving how the system handled errors, and making the overall experience smoother for users. A big part of my work involved debugging real user-facing problems, testing different edge cases, and collaborating with other engineers to make sure fixes were stable and well-built. I also helped improve performance so the product felt faster, more consistent, and more dependable during everyday use. That experience taught me how to solve technical problems with care, write cleaner code, and think deeply about the user experience. I bring that same approach to client work: clear communication, reliable development, and a focus on building software that works well in real situations.
