I founded 26 Lines of Code in October 2017, under its first name, DTEAM. Today it is 70+ specialists in the US, Estonia and Ukraine with 150+ projects behind them, and I run it as CEO from Miami. Since February 2025 I have also been a co-founder and the CTO of HirePilot, a product for job seekers that our team builds.
How I got here
- 2008-2013, freelance web developer. I learned to program on paid projects: online shops, content sites and dashboards, in HTML, CSS and JavaScript, then Python from 2010 and Django from 2013. The degree I studied for at the same time was in avionics.
- 2013-2014, junior full-stack developer at a small studio: from a designer's mockup to a site on a server, handed over to the client.
- 2014-2019, middle and senior Python developer, then CTO at a software agency in Ukraine. The work I remember best: six months building a subscription system from scratch, with plans, add-ons and permissions. I also started a monthly Q&A broadcast for my colleagues, on anything from blockchain to productivity.
- From 2017, my own company. I was its only CTO until a full-time one joined; since then I mostly work as CEO, and as the solution architect on projects that need one.
What I work with
Solution architecture, DevOps and engineering leadership. My own stack: Python with Django, Flask and FastAPI; JavaScript and TypeScript with React and Angular; Docker, GitLab CI and AWS; Linux administration since 2009.
Projects of ours I have led as CEO and architect include RxPhoto, PBM Source and Raina Music.
Education and languages
- Master's degree in Business Administration (Management and Operations), Kyiv-Mohyla Business School, 2025.
- Master's degree in Avionics, National Aviation University, Kyiv, 2014.
- English, Ukrainian and Russian; Hebrew at a basic level.
Before this blog I wrote tutorials on a real-time chat with Django Channels and on the HTML5 Geolocation API. My articles on this site are below.
