Hi there 👋

I am an iOS Engineer (Lead @ NYTimes)

Outside of regular app development I've spent last decade working on creating tools, ideas, and libraries that make the life of fellow Cocoa engineers easier.

Community work

My expertise

I focus on maintainable architecture, improving developer experience and efficiency by:

  • 🤔 Designing flexible architecture that can be easily maintained
  • ⚙️ Creating automation for common code tasks and workflows
  • 👥 Establishing best practices for architecture, testing, and workflows
  • 📋 As a consultant I usually:
    • 🤔 Perform whole project code reviews and provide clients with practical recommendations of things they can do to improve their team efficiency and satisfaction (through better dev experience and automation)
    • 👥 Help establish best practices and provide architecture recommendation
    • 🛠️ Design and implement flexible & pragmatic solutions for hard problems
  • 🧙 A lot more...
