# Julian Ceipek > Seeking to build professional tools for creatives & scientists Location: Greater Boston, United States Profile: https://flows.cv/julianceipek I craft systemic solutions with & for people. I love learning, collaborating & teaching. I have a passion for creating well-designed professional tools that serve the needs of creatives, scientists, and engineers. My experience ranges from interaction design to embedded firmware. Modern software is 100-1000x slower, buggier, and more complex than it should be. I can help change that. ## Work Experience ### Senior Software Engineer @ Lumafield Jan 2023 – Jan 2023 | Cambridge, Massachusetts, United States Delivered faster, more reliable, more usable embedded software for Lumafield's X-ray CT scanners, enabling high-volume inspection usecases in factories. - Reduced per-image processing time 30-50x to enable minute-long scans with quality equivalent to hour-long scans, replacing Scipy/Numpy/OpenCV algorithms with simpler, custom SIMD C code - Improved scanner UI responsiveness 90% while making UI code easier to change and increasing type safety, by writing a Typescript code generator and implementing O(log(n)) instead of O(n) state updates - Led 75% variable cost reduction project to move the 3d reconstruction pipeline from AWS servers to on-scanner CPU+GPU compute for high-volume customers - Root-caused intermittent 300ms system stalls using full-system profiling and reverse engineering tools including NSight Systems, LD_PRELOAD, Cutter, and jemalloc - Worked closely with QA, scanner fleet services, and frontend/backend software teams to implement, troubleshoot, and fix features for customers and internal teams ### Software Engineer @ Lumafield Jan 2020 – Jan 2023 | Cambridge, Massachusetts, United States Developed volumetric renderers, hardware drivers, and server backends for accessible industrial inspection using X-ray CT. - Implemented the core WebGL2 volume renderer customers use to look inside volumetric scans - Developed the hardware driver for the in-house motion system board used in all scanners - Created systems for version migrations and fleet-wide hardware health monitoring - Designed and implemented scan data ingestion and security for the company's cloud server backend - Produced detailed in-house documentation and presentations on software system performance, systemwide profiling, reverse engineering, and writing code that is easier to understand and change - Improved the intern hiring process with individualized feedback ### Software Contractor (2015-present) @ Studio Farahi Jan 2015 – Jan 2023 | Greater Los Angeles Area Create the "brains" for interactive garments and installations backed by Adidas, Steelcase, and Chicago's Museum of Science and Industry; and featured by outlets including WIRED, CNN, The Guardian, BBC News, Engadget, and CNET. - In under 130 hours, engineered complete simulation suite, control system, and wifi monitoring portal for display case that reacts to human emotions. Project presented to executives at Adidas headquarters. - Built visual calibration tool for tuning servo motors in 30 seconds (despite no prior servo experience). - Achieved 20x performance boost for generative animations using game development tricks. ### Founding Engineer @ Lynxtool, Inc. Jan 2020 – Jan 2021 | San Francisco Bay Area Designed, implemented, and documented the the render stack, IMGUI, and data tracing for an in-browser node-based programming environment and worked on the LLVM backend. Company acquired by Figma and then Adobe. ### Engineer @ Dark Jan 2019 – Jan 2020 | San Francisco Bay Area Led initiatives to unify user experience of revolutionary “live” programming environment for backend programmers, with goal of making coding 100x easier. - Developed, documented, and tested standard toolkit with which customers build software used by 10s of thousands of end users. - Introduced new programming paradigms and fixed biggest pain points during regular customer interactions. - Became go-to person to fix most complex problems. ### Developer/Designer @ Tender Claws Jan 2015 – Jan 2019 | Greater Los Angeles Area Created foundational game systems, in-house tools, native plugins, custom servers, and prototypes for critically-acclaimed AR and VR experiences supported by Google and Oculus. - Developed prize-winning first prototype and core multiplatform architecture for award-winning VR game Virtual Virtual Reality, with 50k+ installs and majority 5-star ratings. - Spearheaded and lead development of multiplayer services and backend infrastructure for virtual reality live theater experience showcased at Sundance Film Festival and backed by Oculus. - Amplified the efforts of my talented collaborators; learning, using, and teaching languages, techniques, and pre-release technologies as needed. ### Co-founder @ Carthage Games LLC Jan 2014 – Jan 2015 | Massachusetts ### Engineer Intern @ Codecademy Jan 2013 – Jan 2013 Designed, developed, and user-tested the initial prototypes for the project-based programming lessons that are now central to the company's subscription model. ### Developer/Designer Intern @ Riparian Data Jan 2012 – Jan 2012 Developed production code for browser-based enterprise email client and co-designed the user experience. ### User Experience Research Intern @ LexisNexis Jan 2011 – Jan 2011 First to integrate speech recognition into iPhone app for lawyers. ### iPhone Application Developer @ The Miami Valley School Jan 2009 – Jan 2010 Independently designed, developed, and delivered a web-connected iPhone app for parents and students. ### Youth Mentor for Elementary Students @ FIRST LEGO League Jan 2005 – Jan 2007 I co-instructed a robotics team that achieved state-alternate status. ## Education ### Master of Fine Arts (M.F.A.) in Interactive Media and Games University of Southern California Jan 2014 – Jan 2017 ### BS in Engineering with Computing Franklin W. Olin College of Engineering Jan 2010 – Jan 2014 ### The Miami Valley School Jan 2004 – Jan 2010 ## Contact & Social - LinkedIn: https://linkedin.com/in/jceipek - Website: https://jceipek.com --- Source: https://flows.cv/julianceipek JSON Resume: https://flows.cv/julianceipek/resume.json Last updated: 2026-03-22
