Senior/Lead iOS/ReactNative Engineer

Experience

First of all, I'd like to say that what I love most in my career is helping businesses turn their ideas into robust, scalable, and successful apps by becoming a bridge between their worlds (ideas / economy / investors / timelines / results) and the tech world (code / architecture / scalability / mentoring) so both parties end up profiting. The following experience is what helps me to do this.

I'm a mobile developer with more than 7 years of rich experience with iOS, ReactNative, and React.js. I've been developing / architecting / managing apps in various fields, from cryptocurrency and marketing to emotional intelligence and health, at different scales, from the early stage apps to large production apps with 10+ million active users. I've worked with big companies, such as Sony Music and Microsoft, and start-ups with fast-paced environments to help them deliver the best products.

During my career, I've gained solid fundamental knowledge of mobile/web technologies, design/architectural patterns, TDD/BDD approaches, building successful scalable apps, leading a team/project, etc.

I can be either part of a team, a leader, or alone. I'm not afraid to express my vision, but at the same time, I understand the business side and can help transform business requirements into technical ones.

I also have a good background in mathematics and algorithms, hence excellent analytical thinking and attention to detail.
I regularly participate in various competitive programming contests. It's my hobby, and solving complex algorithmic problems helps me look at difficulties from different angles.

To sum up, I'm at your disposal if you need help to turn your ideas into successful apps or scale existing ones.

Highlights

- One of my ideas/experiments led to the following:
• Apple featured the app on the AppStore
• Increased install-to-trial CVR by 13%
• Increased 7-day retention by 20+%
• Ultimately, increased app revenue by 7%

- Optimised fetching a massive database of 20k contacts at the first app start in a way it started to take about 30 seconds instead of 10+ minutes.

- I led a project related to a crypto wallet, helping both the entire mobile team (iOS and Android) and the backend team. I have consulted on architectural, UI / UX, and business issues.

- Have completed the iOS Lead Essentials Course where I learned a lot.

Looking for

I want to do something meaningful and engaging that could help people around the globe. A team where I can both get new experiences and share mine. I believe that together we can implement a fantastic product and level up ourselves more than individually.
