About Me
Is your React Native app slow, buggy, or stuck in someone else's messy codebase? I help startups, product companies, and agencies turn underperforming mobile apps into fast, reliable products — or build them right from scratch.
Here's the problem I see over and over: You hired a team (or a freelancer) who got the app 70% there. Now it's sluggish, the codebase is a maze, and every new feature feels like it takes twice as long as it should. Or maybe you're starting fresh and you don't want to end up in that situation in the first...

3/2024 - Ongoing
Cross generation Smart TV application for one of the biggest
Latvian tv providers
Platforms: tvOS, Android TV, Tizen, webOS, HiSense, Web
I am a tech and team lead overseeing a team of eight. I created a
monorepo that hosts a single codebase, allowing us to share
nearly 90% of our code across platforms. I also developed CI/CD
pipelines to automate store releases and introduced trunk-based
development to the team. Additionally, I co-created an internal
spatial focus library that is nearly twice as fast as react-tv-
space-navigation.

Cross platform Ed Tech mobile app
I was responsible for developing a scalable mobile app that
serves 1.4 million users. I assisted in leading a team of five and
played a key role in establishing and tracking release processes
using Swarmia. Single-handedly migrated the entire release
process from CodePush to CircleCI. Ported Unity games to React
Native. I have also led the porting of iPad OS. Furthermore, I
developed a backend microservice for a trivia game using
NestJS.

Social shopping app Flip - TikTok meets Zalando
Worked in a team that made Flip a unicorn. I was responsible for
performance optimizations, developing and maintenance of
native modules (SocketIO, live broadcasting, video merging,
livestream analytics, livestream player, fps and memory
analytics), developing new features (filters, shopping experience,
live chat). Created a custom native player (2x faster than
AkamaiPlayer). Created SocketIO wrapper (faster than any other
package on github). Created a React Navigation shared element
transition long before it became possible with Reanimated.
