# Mike Ciesielka > Senior Software Engineer at Product Hunt Location: Greater Philadelphia, United States Profile: https://flows.cv/mikeciesielka My name is Mike Ciesielka, and I'm passionate about things that make me think. If you've got interesting problems, I'd like to help you find interesting answers. ## Work Experience ### Senior Software Engineer @ Product Hunt Jan 2021 – Present | New York, New York, United States - Contributed as a generalist in projects and initiatives across the company: + Led development of our brand new iOS app + Worked as a full-stack web engineer (React + Ruby on Rails) + Helped democratize access to data to generate insights and power decision-making ### Senior Software Engineer @ FanDuel Jan 2021 – Jan 2021 - Maintained and implemented automated integration tests for the iOS Daily Fantasy app, including a mock API server to provide mock data ### Sr. Software Engineer @ Aaptiv Jan 2020 – Jan 2021 | New York, New York, United States - Architected refactoring of large, existing codebase into shared frameworks to deliver modular features across multiple application targets - Continually involved in all feature development and launches, including increased ownership over a rich Apple Watch experience with HealthKit integration, iOS 14 widget, and more ### Software Engineer @ Aaptiv Jan 2018 – Jan 2020 | New York, New York - Central figure in the launch of all major features including an in-app social experience, a recommendation-focused fitness plan, a gamified and reward-focused encouragement system, and others - Advocate for testing best practices in a fast-paced environment at all levels from development to quality assurance to deliver consistent and dependable quality to users ### Sr. Software Engineer @ Pandora Jan 2017 – Jan 2018 | Oakland, CA In a senior role, I've been given a more focused position in driving key projects amongst a deeper set of responsibilities to protect app health and quality. Projects include: - Ad-Supported Pandora Premium: This cross-functional initiative provides our ad-supported and Pandora Plus tiers with the ability to watch an ad in order to get access to a (mostly) full suite of our Premium offering's functionality. - Release Engineer: Mediate with Quality Engineering teams and Product / Engineering to manage individual iOS releases and assess the risk of certain bugs for our users. This role also designates me as a shepherd of code quality and safety within the app who strives to keep crash and bug rates low while keeping app ratings high. ### Software Engineer @ Pandora Jan 2016 – Jan 2017 | Oakland, CA Quickly grew into a core contributor while developing Pandora's first on-demand music experience, Pandora Premium. While I managed to touch many pieces of the final product, my major contributions included differentiated features like: - Add Similar Songs: an automated way for users to extend their playlists - Autoplay: users experience never-ending music that picks up right when your current song, album, or playlist ends with songs recommended by Pandora's acclaimed Music Genome Project - Various data-driven updates: helped to build features with goals to increase performance in key KPI's in the aftermath of the premium launch, such as increasing manual playlist adds Concurrent with the work above, I've been a regular advocate for: - Modernization: I've helped to create an enthusiasm surrounding Swift and the continued improvement of Pandora's legacy structures with hopes of using the best and newest tools to provide a more maintainable and stable app - Accessibility: building products for mobile applications means building them for a variety of users, including the vision-impaired. Promoting awareness for VoiceOver users has helped to keep Pandora a preferred destination for such users, and has inadvertently assisted our automation team's ability to protect against regressions and maintain app health. ### iOS Engineer Intern @ Pandora Jan 2015 – Jan 2015 | Oakland, CA • Refactored legacy code while implementing some top-level architecture modifications to adapt the Pandora iOS app to prepare for split-screen multi-tasking on the iPad introduced by Apple at WWDC in June 2015 • Assisted in some minor user-facing bug-fixes related to UI issues and accessibility ### iOS Developer @ Kode Jan 2014 – Jan 2015 | Greater Los Angeles Area • Converted specifications from a designer to a functioning and scalable iOS application complete with “Auto-Layout” fluidity across mobile devices as a freelance worker ### Lead Developer @ OffPeak Jan 2014 – Jan 2014 • Contributed as the lone developer of a small, three-person company to implement an iOS mobile application connecting local restaurant owners and undergraduate students available at three universities beginning in the 2014-2015 school year • Developed an online control panel for administrators and restaurant owners to interact with OffPeak promotions and monitor their business’ success • Adapted to Parse’s iOS and Javascript SDKs on-the-fly to react to the demands of a fast-paced development cycle and create software to the standards of the product manager and designer ### Research Assistant @ University of Southern California Jan 2013 – Jan 2014 | Los Angeles, CA • Collaborated with professor Seon Ho Kim, graduate students and undergraduates at the Integrated Media Systems Center at USC to create a mobile application integrating media, crowdsourcing, and geographical metadata now being used in more than five locations around the world • Attained a foundation in the Android SDK by processing and learning the functions of the existing application and adding new features thereafter ## Education ### Bachelor of Science (B.S.) in Computer Science University of Southern California Jan 2012 – Jan 2016 ### Plymouth-Whitemarsh High School Jan 2008 – Jan 2012 ## Contact & Social - LinkedIn: https://linkedin.com/in/maciesielka --- Source: https://flows.cv/mikeciesielka JSON Resume: https://flows.cv/mikeciesielka/resume.json Last updated: 2026-03-22
