Hi, I'm Alexey — a full-stack engineer working with Node.js, Next.js, React, Ruby on Rails, Google Cloud, Shell Scripting, and PostgreSQL. I combine strong backend, frontend, and cloud skills with modern AI tools and prompt engineering practices to deliver efficient, high-impact solutions.
Full-stack project management website inspired by Trello. Built with Ruby on Rails for the backend, PostgreSQL as the database, JavaScript, React, and Redux for the frontend. This app implements core CRUD functionality using RESTful API for desks, lists, and papers. It remotely stores users’ profile pictures in the cloud via AWS S3 to reduce server load.
Professional networking application that allows users to connect in a simplified manner. This app is built with Express.js / Node.js for the backend, MongoDB as database, Mongoose library for a schema-based solution to model application data, and finally React / Redux, and JavaScript for the frontend.
I started my career in Russia as a professional ice hockey player
and a student of International Relations, where I developed
resilience, teamwork, and a global perspective. After moving to the
United States, I transitioned from building physical structures to
building digital products.
In 2020, I completed an intensive software engineering bootcamp in
San Francisco, gaining expertise in JavaScript, Ruby on Rails,
React, Redux, and PostgreSQL. I contributed to open-source projects
with Hack for LA, collaborated in Agile teams, and built
production-ready features at Sidebar.
I'm a Software Engineer II at Formally, where I scaled core
platforms, led architecture improvements, and mentored teams. I work
across Node.js, Next.js, PostgreSQL, Python, Shell, and GCP —
blending strong engineering with AI-driven workflows, load testing,
and customer-first product delivery.
I'm passionate about building reliable, scalable systems and helping
teams move faster and smarter. Let’s connect!
