I'm offering
I am experienced front-end consultant with a focus on solving challenges and fulfilling business requirements by use of technology.
I have more than 6 years of commercial experience in Front-End development. Having extensive knowledge of JavaScript, I can work with different front-end frameworks and libraries. However, in the last 4 years, I work with ReactJS stack on a daily basis. While I am considering code reviews and pair programming as a large part of my job, I can equally undertake work on my own. I have experience with contemporary front-end architectures, SSR, PWA and performance optimisation. Moreover, I have an eye for design and enjoy working closely with creative teams. I can work on small to medium-sized NodeJS projects; however, it is not my main specialisation.
I am always open to explore new opportunities and happy to discuss how my expertise can benefit your business.
Inclusive but not an exhaustive list of my technical skills:
- JavaScript, TypeScript
- ReactJS, Redux, Apollo, NextJS
- CSS, SASS, BEM, CSS modules, CSS in JS solutions
- NodeJS
- Webpack
- TDD
- Sketch

Founder & Lead Consultant
Right Thinking.
Right Thinking is a small outsourcing consultancy. I started the company in 2018 to close the gap between development requirements of UK-based companies and highly skilled web developers based in countries such as Lithuania, Russia and Ukraine. We provide our clients with flexibility and cost-saving opportunities while ensuring the highest quality of the provided services. Our main specialisation is front-end development; however, we have a proven track record of full-stack and mobile application development.
Leading a small team of web developers spread around the world, I constantly participate in the development of technical solutions to meet the requirements of our clients. As a founder, my responsibilities include but not limited to business management, communication with clients and their representatives, screening and hiring of developers.

Issues with render-blocking scripts as well as ineffective JavaScript and CSS delivery were identified and eliminated. A part of the website functionality was successfully refactored and migrated to a standalone ReactJS application based on NodeJS server-side rendering in order to utilise Google PRPL pattern and optimise critical rendering path.

The work was involving close collaboration with the design team to increase website conversion by utilising A/B testing approach. Moreover, I was given an authority to successfully make strategic decisions to modernise technical stack as well as improve reliability and maintainability of the front-end codebase.
