Position: CTO / System Architect
Category: Lead
English level: fluent
Years of experience: 11

At current job:
Got hired by the CTO at that time, but 4 month later turned out that he must leave Belarus because Trump tightened migration regulations and he had a risk of losing green card. Being the first developer, who has been in process of interviewing future team members I was the only one developer left in company. Today we have strong dev teams (mobile, DevOps, frontend, backend). Half of members got hired being Juniors with only The Rolling Scopes School courses as IT background (tho we had interviews only with best of best). Today those Juniors already teaching new professionals in both RSS and inside a company, showing great performance in parallel

Created technical roadmap, together with full product vision via hot discussions with stakeholders. Of course, it was updated many times due to different hypothesis testing and a better understanding of client needs. But main ideas and values is kept unchanged since those days. 
Designed, verified, and developed a cryptology core of the product. Created PoC to utilize that code. This allowed company to successfully raise the first round. 
Created MVC to close another round. And added many features, designed initially to work with crypto core, along those years.
Security concepts, from white paper to source code verified by different independent auditors.

Streamlined Delivery process of the product on all stages. From automatically created environments for each opened PR to Release stage when Product Owner have to click just a few buttons in order for new version to be released. Important note: We do releases every 2 weeks because field specifics (privacy-focused product) require a lot of additional testing before release can be made. This is one of the big disadvantages you have developing a product that utilizes the strictest zero-knowledge approaches about user data. Infra stack: Kubernetes, Docker, Docker-compose, Helm, MongoDB, Redis, Terraform, Ansible, TeamCity, Prometheus, Grafana, Sentry, ELK, Ceph

Created uniq, democratic work environment where no one is afraid to criticize and ready to be criticized for the best of the company.
2010 - 2013 elance and odesk (thanks dad for ordering bank card and helping with docs!)
2014 - Beetsoft - Local outsourcing company. Somehow at that stage they made me hate PHP and almost every framework available at that time. Also worked at Pet Projects in order to find  another backend language to fall in love  (they all are dead now, like most of google projects )
2015 - Worked on ERP for local company in my native town. JS ultra stack: from infra to backend to frontend including everything in between. One of best kickoffs from the cliff someone trying to overcome middle level may have)
2016 - Worked on first version of squadintouch.com 
-----   Decided to move out of Russia to Belarus:  -----

2016 - SolarWinds (ex. LogicNow, ex. IASO Backup) - worked on "system frontend" which included ultrastack infra/backend/frontend of CCTV system to be integrated with backup solution developed by company. Long story short: After 8 months of working in the company it got acquired, project is closed. NDA is expired so I will be happy to discuss pitfalls and nuances here, one of most fun experiences I've had!
2016 - 2017: iFuture - worked on mobile version of one of most popular betting websites - marathonbet (coffeescript, flux, and the rest of techs to scare the youngest of us)

2017 - now: Decided that time has come to make next step in career growth. Got very good offers from two companies, tried in both (yep, full-time, since hoped sleep that isn't mandatory). 3 months: burned out, sticked with just one company and till now work on privacy-focused product. Check Achievements for more info about what was there ;)

P.S. The funny term ultra stack from my PoV is only way how devs may stop asking colleagues from DevOps department dead-simple, yet complicated questions. And the reason why I'm scared by the rise of ultra-simplified backend (e.g. firebase) from Google&Co. No way to break those fragile instances or completely mess-up with the cluster (its 2022, after all)
Nice to haves:
* Fintech or related to crypto
* Ability to maintain honest and clear communications. Not all C-Level managers are ready to listen when their mistakes are highlight, even in private discussion. 
* Helping hand in analysing current processes, readiness to change and adapt them
* Startup at early or scale-up phase
