About

• Helping clients with architecture, performance and developer experience improvements.
• Running workshops and training sessions for engineering teams.
• Building AI powered tools and workflows to improve developer productivity and velocity.
• Clients included: Vinted, Polymarket, Shotsy, The New York Times and many others.

• Created a lot of internal developer tools and optimized the development workflows for the whole team, leading to increased productivity and efficiency for the entire team.
• Implemented architectural improvements and boosted testability, significantly enhancing the project’s overall quality.
• Established best practices and cultivated a strong team culture, resulting in a highly effective and collaborative engineering environment.
• Actively contributed to building the company’s engineering brand recognition, attracting top talent and fostering a reputation for excellence.
• Created the onboarding experience
• Led the main home feature (Library)

Lead development of two applications:

1. A complete rewrite of our main Newsreader app, I started leading with a team of ~12 engineers and grew it to 20+ engineers.
2. Education application for Kids. Designed a completely new architecture and build real time preview system for editorial team.

Outside technical leadership, I’ve focused on creating a improving developer experience for my teammates through innovative architecture and tooling.

• I’ve built an Observable library for the company that would be a foundational block for all iOS codebases, it’s a simplified model of FRP that’s easier to understand, the team at the time didn’t know FRP, but we wanted to get the best out of MVVM+C
• Established best practices, wrote numerous guides and internal talks
• Created high-level abstractions that enabled simple Snapshotting of our view layers
• Lead multiple development workflow revamps that save us a lot of time when building the projects
• Built a 2-Way communication bridge between JS and Native that lets native developers add new features without dealing with any JS related code
• Additionally I’ve built the ARKit/SceneKit integration into the bridge, on this platform we won Emmy awards and Webby award
• Built an early warning system, that lets us warn developers when unexpected behaviour happens in the application, can also be tested via UITests.
• SLO’s / Performance tracking system that would lead us to easily understand what’s going on in our apps
• Built a data snapshot system that allowed us to reproduce bugs that would otherwise be extremely time-consuming to reproduce given the quickly changing feeds News has
• Heavily automated A/B testing solution
• Heavily automated beta settings that removed thousands of lines of code we had to maintain and streamlined the whole process
• Helped build a spelling bee game in Flutter

Worked on a new social application based around video.

• Worked on a video app for content creators
• Implemented innovative custom user interfaces and interactions for both creation and consumption flows
• Implemented a low level AVFoundation based resource manager that allowed to stream and cache videos at the same time for better UX
• Grew Flex (unidirectional) based architecture in Objective-C

Joined as Senior contractor working remotely, after 2 months became technical lead for European team.

• Design and implement maintainable architecture for our clients like H&R Block.
• Implement many custom UI interactions
• Coordinate work of other developers in the teams
• Improving process and quality of code, and teaching other developers through writing and internal talks.

Joined as Senior engineer, after 7 months became lead engineer.

• Lead the 10+ engineering team and making sure every project was running smoothly
• Hands-on I’ve also designed and implemented maintainable architectures and innovative UI for clients like Headspace, News International, Unilever and many others.
• Modernised and automated workflows for projects like Talk Talk XFactor / TV Heads
• Lead development of few new projects for UK retailers

• Created fully animated and interactive interfaces for apps to be used at medical conferences

Worked on multiple platforms before settling in on iOS.

• Lead multiple projects
• Helped optimise mobile application for map navigation
• Developing many custom views, including usage of OpenGL-ES 1.1 and 2.0
• Created press publishing platform “Pixblish”
• Worked on 2 apps for one of the biggest multinational energy companies.
• Created framework for graphical applications (OpenGL-ES 2.0) and developed few games(5+) on it for Samsung Bada.
• Created custom LockScreen with physics for android.
• Art app for german fashion house Michalsky

I’ve co-founded a mobile studio with two designers, we created 5 award-winning apps.

• Sole engineer on 5 applications
• All of them were featured by Apple in many categories
• Apple’s ‘Best App of 2013’, ‘10 Apps That Wow’ and Apple Design Award nomination
• My apps were featured in over 400+ services, TV shows and even by Kara Swisher
• Coined an entirely new concept called Behaviours that enabled non-engineers to easily contribute logic changes to the apps

Before transitioning to iOS development in 2008, I spent years building game engines and 3D graphics systems from scratch. This foundation in low-level systems programming and real-time graphics profoundly shaped my approach to mobile development—particularly my focus on performance optimization and smooth user experiences.

Engine & Rendering

• Built multiple full 3D game engines supporting both DirectX and OpenGL
• Implemented advanced rendering pipelines (forward/deferred rendering, shader systems)
• Designed a WYSIWYG editor with automatic shader code generation

Core Systems

• Created custom RTTI/Reflection and Serialization systems in C++
• Developed proprietary scripting language for game logic
• Built custom UI and Physics frameworks
