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)

I love sharing knowledge, live coding, and mentoring (helped over 15 devs go from junior to intermediate in the last three years). Experience with leading projects, project management, and running startups. Frequent conference speaker and organizer of NisJS, a local JavaScript meetup in Nis, Serbia.
