In total, I have 3.5 years of development experience, with hands-on involvement in various projects. I have successfully created products from scratch, built Minimum Viable Products (MVPs) in extremely agile environments, and integrated into large-scale projects for further maintenance and scaling.

Throughout my career, I have proven myself as a valuable team member in product companies, outsource teams, and while working as an outstaffed developer.

I am proficient in communicating with teams and stakeholders in three languages: English, Ukrainian, and Polish.

My technology stack consists of:

3+ years of experience: React, Redux, Sagas, styled-components, Webpack, vanilla JS, Git. 
(I have used these technologies in almost every project and continue to use them in my day-to-day work routine.)

1.5+ years of experience: TypeScript, Next.js, MaterialUI, TanStack Query, AntDesign, Node.js, Express, Fastify, PostgreSQL, GraphQL, Sequelize, Cypress, Jest, Docker, Kubernetes. 
(I have commercial experience with these technologies, having worked on multiple projects and gained hands-on experience.)

0.5 year of experience: Solidity, Ganache, Truffle, React Native, Vue, Python, AWS, Electron. 
(While I have limited commercial experience with these technologies, I have had the chance to use them in one commercial project or completed courses and developed a pet project.)
Having experience working in product, outsource, and outstaff companies, I strongly believe that a product company would be the ideal environment to make the most of my attitude and mindset.

I am also open to considering opportunities with outsource companies that involve long-term projects starting from the ground-up.
