# Dana Oira Shi > Software Engineer at Celonis | Frontend & Data Visualization Enthusiast Location: San Francisco Bay Area, United States Profile: https://flows.cv/danaoirashi **Note to recruiters: Please do not reach out to me about full stack or backend engineer positions. I will only respond to frontend engineering or data visualization opportunities. I am a Frontend Engineer who is passionate about writing code for good by making difficult problems more tangible through interactive data visualizations. I enjoy working heavily in the frontend with data visualizations as a primary component of a company's product portfolio. Opportunities in the health tech space are of interest to me and is a nice to have, but data visualization is a must for future opportunities. As of 2026, I have 5 years of experience with React, D3.js, Redux and 3 years of experience with Angular, Typescript, RxJS, and Jest. I also have worked with Jira, GitHub, Atlassian ecosystem, Figma, Datadog, i18n, a11y with more as my tech stack increases. I have 7 years experience in the full software lifecycle from the architecture, software design and development of product frontends from scratch, having had experience in the founding frontend engineering team in an AI supply chain and logistics startup. I also have experience with software maintenance, complex refactor efforts from upgrading code bases from Angular to React to refactoring frontend code to be more scalable and performant not just on the user end, but also for my fellow frontend engineers. I've also done complete refactors of state management from Redux to React hooks as well as refactoring data integration in collaboration with API software engineers and data engineers to improve performance on the frontend as well as streamline the data ingestion point to make data integration in the frontend development easier. ## Work Experience ### Software Engineer @ Celonis Jan 2022 – Present | Palo Alto, California, United States At Celonis, I work primarily on the Frontend stack.
