# Sophia Ottleben > Senior Software Engineer - CT Image Generation Location: Milwaukee, Wisconsin, United States Profile: https://flows.cv/sophiaottleben Senior Software Engineer with 6 years of software engineering experience. Currently working at GE, where I contribute to the development and optimization of GPU-based image reconstruction algorithms for photon-counting CT scanners. I collaborate with global teams to translate Matlab and Python algorithms into efficient C++/OpenCL/CUDA implementations, integrating them into larger imaging frameworks. I also conduct image quality analysis and performance evaluations to ensure the robustness and precision of both new and existing algorithms. Previously, I worked at Polco as a Full-Stack Senior Software Engineer, developing new product features for a civic engagement web application in a fast-paced, lean/agile startup environment. My major projects included setting up AI Assistant integration, SSO integration, Role-based Access Control (RBAC) for administrators, and an Idea Submissions feature. I also contributed to system architecture projects, creating microservices and implementing an ORM to support the migration from a monolithic to a scalable microservices architecture on AWS. Skilled in C++, OpenCL, CUDA, TypeScript, React, Apollo GraphQL, Prisma, and PostgreSQL, with a strong foundation in biomedical engineering. I hold a Bachelor of Science in Biomedical/Medical Engineering from Johns Hopkins University and a Professional Capstone Certificate in Computer Science from the University of Wisconsin-Madison. ## Work Experience ### Senior Software Engineer - CT Image Generation @ GE HealthCare Jan 2024 – Present | Waukesha, Wisconsin, United States • Designed and optimized GPU-based image reconstruction algorithms for photon-counting CT scanners, driving advancements in medical imaging performance. • Decomposed Python and MATLAB algorithms and technical specifications into parallelizable tasks, enabling cross-functional collaboration, accelerating delivery timelines, and minimizing bottlenecks. • Directed communication across global teams to translate MATLAB and Python algorithms into efficient C++/OpenCL/CUDA implementations, integrating them into broader imaging frameworks. • Conducted image quality analysis and performance assessments to ensure the robustness and precision of both new and existing algorithms. • Managed agile workflows, guiding sprint planning, feature prioritization, retrospectives, and team execution while mentoring team members to achieve project milestones. • Conducted design reviews and created UML diagrams to extend infrastructure with third-party library functionality, applying consistent patterns to support additional integrations. • Delivered the first implementation leveraging platform team infrastructure to create performance dashboards—providing leadership with improved visibility into key metrics and offering feedback to enhance the platform’s capabilities for future use. • Mentored junior developers in completing self-assessments and setting goals focused on design rigor, scoping technical requirements, and making informed architectural decisions. ### Senior Software Engineer @ Polco Jan 2022 – Jan 2024 • Led a team of 4 engineers following the Scrum framework through successful project lifecycles • Worked with product owner and UX Designer to write PRDs • Mentored the engineering team to translate PRDs into technical requirements and manageable goals according to our Scrum process • Improved code quality by providing code reviews for Junior Engineers • Implemented web features using: Git, CI/CD pipeline, React, Bootstrap, Apollo Client, TypeScript, REST APIs, Jest testing framework, Prisma ORM, and PostgreSQL database • Analyzed latency issues and coached the engineering team on ways to scope out solutions • Completed a product-led growth (PLG) project that provided existing users access to a demo application in order to upsell features • Setup infrastructure for auto-generating API documentation for ApiGateway Endpoints • Owned implementation of Prisma to increase efficiency when working with the database • Created database model, API endpoints, and web page of a RBAC and Idea Submissions feature ### Software Developer @ Epic Jan 2019 – Jan 2022 • Contributed to web (C#) and server (MUMPS) development of population health software products from requirement definition through successful deployment • Provided guidance and timely solutions to implementation and technical issues with the software • Maintained functional-area ownership of software for social determinants of health screening tools • Provided user-requirement analysis and led design conversations for medical software that aided in screening for and addressing social determinants of health • Used the following programing languages: C#, Java, MUMPS, and TypeScript ### Quality Assurance Team Lead @ Epic Jan 2018 – Jan 2019 • Managed team members’ workloads, provided constructive feedback, and aligned their skills and interests with the areas they were working on. • Led development projects while managing customer expectations and working with the development team to meet project timelines. ### Quality Assurance Tester @ Epic Jan 2015 – Jan 2018 I supported the design and quality of Electronic Medical Records software at Epic. This involved understanding the end user's needs, but also knowing how our software could help create a more effective, safer work environment. I worked directly with the software developers to help come up with design solutions that accomplish the end goal and I tested the software to ensure that the product was high quality. • Completed a variety of testing techniques including functional, usability, performance, integration, and stress testing. • Attended onsite hospital visits to learn how analysts, pharmacists, nurses, and doctors interact with the software. • Managed projects for new features including development for international customers. • Participated in Root Cause Analysis meetings to come up with solutions on how past problems could be avoided. • Hosted webinars for our customers about new features in our software. ### Johns Hopkins Underrepresented in Medical Professions (JUMP) Intern @ Office of Multicultural Affairs Jan 2013 – Jan 2015 | Baltimore, Maryland JUMP is a collaborative program whose mission is to promote the success of students from underrepresented populations that are interested in pursuing careers in medicine and other health professions. Visit this link to learn more: http://oma.jhu.edu/programs/jump-initiative/ As a JUMP Intern, I planned and coordinated events held for members of JUMP. I also produced the monthly newsletter and maintained the JUMP website page. ### Undergraduate Research Assistant @ Carnegie Institution for Science Jan 2013 – Jan 2015 | Baltimore, Maryland Worked as an undergraduate research assistant at the Carnegie Institution for Science. The study of this lab was to find translocations and linkages between genomes that could lead to the explanation of the D. Melanogaster-Wolbachia relationship. ### CIIP Summer Program Coordinator @ Thread, Inc. Jan 2014 – Jan 2014 | Baltimore, Maryland The Community Impact Internships Program is a competitive, paid summer internship, that pairs JHU undergraduate students with nonprofit organizations and government agencies to work on community-identified projects in Baltimore. I coordinated the Thread Summer Job Program which involved placing high school students in jobs that would teach them life skills. I worked with both the employers and students to make sure that each party was satisfied with their placement. ### Undergraduate Research Assistant @ The Johns Hopkins University School of Medicine Jan 2011 – Jan 2013 | Baltimore, Maryland Worked as an undergraduate research assistant in the Department of Anesthesiology and Critical Care Medicine. The study of this lab was to understand the role of H2S in Sepsis. ## Education ### Bachelor of Science (BS) in Biomedical/Medical Engineering The Johns Hopkins University Jan 2011 – Jan 2015 ### Professional Capstone Certificate Program in Computer Science University of Wisconsin-Madison Jan 2016 – Jan 2018 ## Contact & Social - LinkedIn: https://linkedin.com/in/ottleben --- Source: https://flows.cv/sophiaottleben JSON Resume: https://flows.cv/sophiaottleben/resume.json Last updated: 2026-03-22
