About Mark Koester, Founder and Lead UX Designer and Developer

Hi, I am Mark Koester, and I have over a decade of hands-on experience taking digital products from ideas into production as a UX Designer (3+ years), Product Manager (5+ years) and Developer (8+ years). I've helped design, develop and launch dozens of digital products.

Some of my past clients include Nissan Auto, Basic.AI, BookLoversCon, Funding Innovation Network, International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), and many others.

Besides product development, I am active open source developer and a serial tech entrepreneur having funded and launched multiple products in the e-learning, events, health and data science industries. I have also organized hundreds of events and developed unique programs for e-learning and entrepreneurship. I have helped hundreds of companies as a mentor and advisor, having served previously as regional director at Techstars in China. I currently serve as a co-director of Startup Boost Los Angeles, a pre-accelerator program helping startups get funded.

Some of my recent personal product work includes Biomarker Tracker, PhotoStats.io, PodcastTracker.com and QS Ledger.

Key Elements of My Process:

  • What do the users want?: User Research and UX Design
  • How might we build it?: Tech Assessment and System Architecture
  • Build and Ship it: Full-Stack Software Development
