About Alexey

Please visit my portfolio website https:// lexer.dev

I'm a Senior Software Engineer with more than 11 years of hands-on experience in building scalable, maintainable, complex technical projects.

I have solid experience in:
- Software project architecture, working with monolithic as well as microservice architectures;
- Developing enterprise software and system architecture design;
- Developing sophisticated and extendable web applications from scratch;
- Working with legacy code, rewrite code, reduce tech debts;
- Software troubleshooting and fixing tricky defects;
- Designing and configuring CI/CD project workflows;
- Leading the team, interviewing candidates and mentoring for newcomers and junior developers;
- Working with agile frameworks like Scrum and Kanban.

My main stack is Javascript, TypeScript, Node.js, React, Firebase, Google Cloud Platform, AWS, Rest API, Express, WebSockets, CI/CD

Recent projects I worked on are decentralised autonomous marketplaces for IoT devices with integrated blockchain (DLT) & cryptocurrency payments, automotive eCommerce, analytics dashboards and data analysis tools, investing application, eCommerce online store serving >100k monthly users.

Technical culture: I follow the idea that software engineers must always be all-sufficient when it required to solve business needs. I can lead any task in any stage of delivery pipeline – analysis, decision research, architecture design, planning, implementation, review, testing, deploying, writing end-user instructions and gaining feedback from the real world. I always remember the initial idea, which business wanted to implement with a task. I'm able to work in startup-style – implement each feature pragmatically and as fast as possible, to get feedback from the real-world faster. With hard problems, I'm always looking for a short-term workaround, which allows gaining the time for solving the issue properly (which often is long-time).
