I was a CTO at a startup, where we had to build real-time system from a scratch. A system had to be built with scalability in mind, to provide a platform, where dozens of people would interact with a specific peace of data. We had to ensure that they all see updates of each other in real time, are able to receive & give feedback on actions of others. The key point of all of this was a backend that utilised smart database-level transactions & socket across multiple server instances.

Another case that I was put on a tight schedule to implement a rich feature-set in a really old mobile app that was using Cordova. Despite the outdated technologies, with a team we were able to properly get use of React, quickly implemented  complicated features using modern technologies & develop a mechanism to insert the build into in app, which saved our client a lot of money.

I was a co-teamlead in a project where we had to build a meetings platform, which is capable of hosting up a dozen of members in a room & up to 15 thousand people watching the livestream of this room. This system were able to support real-time audience votes, speach request, room promotions & a lot of other cool stuff.

I was backend & mobile app develper in a Health-tech platform that connected pharmacists & pharmacies. The platform was dealing with constant hiring process, candidates, reviews, shifts & most importantly - with actual salaries payment.

I was CTO in project that was a universal scheduling Telegram bot, that could parse any university schedule from the website, structurise it and serve to students on weekly basis. The project was complicated due to the diversity of different schedule formats, yet it proved to be working with no issue for more than 5 years.

Besides work projects, I was also participating & winning in dozens of Hackathons, both in Ukraine & in global ones. Was a special guest at Slash & Junction that take place in Finland every year as biggest hackathon & startup conference respectively.
