15+ years of experience with iOS and over 190 iOS applications written in Objective-C and Swift. 16+ years of lecturing experience (iOS, OOP, Software Architecture) Mentoring others is my first love - and I have a tone of experience in that field. I started teaching others math, electronics, and electrotechnics and after some time - I started working for a couple of IT schools where I teach iOS and teach people to think differently.

I enjoy buildings things and solving problems. Problems don't exist in a vacuum and it's necessary to adapt any solution to the business or technical requirements at hand. My mantra is to hold myself to high standards of a software professional. This means that I am committed to: write the best code I can produce in the scope of the project, accountability, responsiveness, and setting clear expectations. Currently I'm exploring the Blockchain world, mainly focused on Ethereum and developement of Decentralized Applications using bleeding-edge technologies. I'm actively working as CTO @ Avalaunch, the official Launchpad of Avalanche ecosystem. In the last few years, I spoke and held workshops on the most notable Blockchain events all around the world: (After Covid-19 pandemic due to huge work overload, stopped attending conferences) * Ethereal Summit 2019 Tel Aviv Blockchain Week : [https://www.youtube.com/watch?v=5JtaEbVkxfc&t=4s](https://www.youtube.com/watch?v=5JtaEbVkxfc&t=4s) * Defi Dapps&Days 2019 Tel Aviv Blockchain Week: [https://www.youtube.com/watch?v=7rpNFP0yiEM&t=523s](https://www.youtube.com/watch?v=7rpNFP0yiEM&t=523s) * Blocksplit 2019 Split : [https://www.youtube.com/watch?v=xaE7-KHVXFw](https://www.youtube.com/watch?v=xaE7-KHVXFw) * EthCC 2020 Paris: [https://www.youtube.com/watch?v=fV5IvrPhpdc](https://www.youtube.com/watch?v=fV5IvrPhpdc)
