ABOUT ME

Senior full-stack developer

I am an experienced engineer with a broad full-stack skillset, currently specializing in backend development (Rust / Node.JS) and DevOps.

EXPERTISE

Rust

3 years experience

I'm a huge Rust enthusiast. My most recent job was to lead the transition of a large project's backend codebase from Node.JS into Rust.

JavaScript

7 years experience

I've created complex fullstack applications in JavaScript (Node.JS + React).

React

For the past 5 years React has been my primary tool for frontend development. I have worked with many libs that solve common problems (mobx, redux, react-virtualized, etc), tried various approaches to state management (see my article - what is the best state container library for React?). Most importantly, I understand React in-depth, including rendering and reconciliation mechanics.

Node.JS is more than a framework for building backends in JavaScript. It is an ecosystem. Good command of Node.JS is a must even for a frontend JavaScript developer. Whereas in React I advocate for functional approach, in my backend JavaScript applications I usually stick to object-oriented approach with dependency injection.

GraphQL simplifies development a lot, but also comes with some unique challenges. I have developed a personal set of best practices to design maintainable GraphQL API and solve common problems on both frontend and backend.

I use TypeScript even in my smallest projects, primarily because of DX benefits that it provides. Developers sometimes avoid using TypeScript because it limits their freedom in some way, but in my opinion it is not a valid reason with modern TypeScript features, such as conditional types. In some cases, especially on backend, TypeScript can even reduce the amount of code you have to write, thanks to the Reflect API feature.

MongoDB

2 years experience

I often use Mongo as a primary database in my pet projects.

What is the best state container library for React?

Spoiler: I generally use none. And you might not need one either. First, I’d like to underline: I’m not saying that any of the below listed libraries are useless or that you shouldn’t be using...

I initially joined Leviosa as a full-stack developer and helped lay the foundation of their frontend SPA. As the team grew, I specialized in a backend development role. Among other things, I helped design flexible and robust GraphQL APIs, was a key contributor to development of early prototypes in Node.JS, and later led the transition of the server codebase to Rust, improving the performance, reliability, and security of the system. I also engineered and implemented the CI/CD pipeline using Kubernetes, Docker, and GitHub Actions, enabling fast and consistent delivery of features and updates. Additionally, I mentored junior developers and helped them learn Rust and best practices for web development.
