Summary
Sean Doe-simkins is a Senior Software Engineer based in Chicago with 13 years in tech and nine years focused on building accessible, high-performance web UIs. He specializes in TypeScript, React, and Angular, and has spent the last four years driving front-end rewrites, feature work, and test coverage across adtech and insurance domains. Sean combines hands-on coding with team leadership—mentoring juniors, conducting technical interviews, and improving hiring and sprint processes to reduce defects and technical debt. His track record includes leading accessibility fixes that dismissed a lawsuit, onboarding engineers through documentation and training, and contributing to acquisition-stage product work at Logik.io/ServiceNow. He thrives in cross-functional teams with Product and Design, balancing pragmatic delivery with maintainability. Unusually for an engineer focused on front-end UX, he also has product-owner experience early in his career, giving him a strong sense for metrics and customer-facing tradeoffs.
