Background

About Andrii Streltsov

I’m a hands-on Senior Software Engineer with over 10 years of experience building web applications using the MERN and MEAN stacks. Since 2014, I’ve worked on a wide range of projects, from single-page apps to complex, microservice-based systems. My focus is always on writing clean, maintainable code that solves real problems.I’m most comfortable working with JavaScript and TypeScript across the stack, utilizing React, Next.js, Angular, and Node.js (Express/NestJS). I’ve also worked with PHP (Symfony2, Laravel), MySQL, and MongoDB. Version control and task tracking with Git, Jira, Trello, and similar tools are second nature at this point.In my recent role, I’ve been supporting and scaling a large e-commerce platform built on a microservice architecture. Beyond coding, I mentor junior devs and collaborate with designers, testers, and product owners to plan and ship features that matter.I have a Master’s degree in Physics and bring a sharp, analytical mindset to every project. I’m always up for a challenge — especially when it involves building systems that are robust, scalable, and easy to live with.
