Hey, I'm Oleksandr Ratushnyi
I'm javascript engineer from 🇺🇦 Ukraine and I like Typescript. I have a passion for creating beautiful and functional web apps. I have experience in saas, fintech and other industries. I able to work with a wide range of technologies and tools in both front-end and back-end development. I am a big fan of the React,NestJS and PostgreSQL, but also I have experience with React Native, Vue, Next.js, Remix, Firebase, Supabase, GraphQL, Node.js, Fastify and other technologies.
I have experience in teaching and creating courses on front-end development. I have successfully graduated several groups of students into front-end development. In addition, I developed my own course for Merge Academy.
When I'm not coding, you might find me capturing life through a lens 📸, riding a bicycle 🚴, perfecting my pizza recipe 🍕, or embarking on tourist trips with a tent 🏕️. Check out my photography Instagram.
At home, I have to two red cats 🐈🐈, though one is not quite as red as a desert.
my work 🗂️
I began my journey in web engineering in early 2018. Over the years, I have held various positions including front-end developer, full-stack developer, and CTO at an agency. Despite my progression into leadership roles, I primarily identify as an engineer.
