What I'm looking for
I am a full-stack software engineer with over 13 years of experience in building scalable web applications for startups and high-growth tech companies. My expertise lies in modern JavaScript frameworks and backend technologies, including Node.js, Python, and Ruby on Rails. I have a proven track record of designing APIs, leading product features from concept to completion, and optimizing performance in complex systems. My strong focus on developer experience, clean architecture, and cross-functional collaboration allows me to thrive in fast-paced environments.
At Stripe, I played key roles in developing high-performance, accessible UIs for global merchants and enterprise clients. I engineered reusable components, improved frontend performance, and led efforts to modernize build pipelines. My experience at Shopify further solidified my skills, where I transitioned from a junior engineer to a senior role, owning key features and mentoring new hires. I am passionate about leveraging technology to solve real-world problems and enhance user experiences.
