I'm a software engineer with a passion for building scalable cloud-based systems and automating complex workflows. I design and ship end-to-end solutions, integrating asynchronous data from multiple APIs and driving continuous delivery. My work at Insulet and previous freelance engagements has sharpened my ability to ship reliable software with a focus on performance and user experience. I've led architecture initiatives, mentored teammates, authored rigorous design docs and workflow diagrams, and built automation that simplifies repetitive tasks. I'm comfortable working remotely with cross-functional teams, and I enjoy turning vague requirements into concrete products through iterative development and strong collaboration.…I'm a software engineer with a passion for building scalable cloud-based systems and automating complex workflows.
