I designed and implemented RESTful APIs, significantly reducing response times and ensuring high system uptime through effective cloud management. My experience also includes mentoring junior developers, which has contributed to improved team velocity and overall project success.

Previously, I worked at Meltano Inc, where I designed core backend services for an open-source data integration platform, enhancing data pipeline throughput by 40%. My background also includes frontend development at Toast Inc, where I developed responsive user interfaces that increased user engagement. I am passionate about leveraging my skills to create impactful solutions and drive innovation in technology.
