Description

Hello!

I am a Fullstack Software Developer with a focus on web development. I have experience with everything from simple personal websites to multi-tenant SaaS systems. I am most comfortable with TypeScript, various JavaScript runtimes, and frameworks like Next.js and Nest.js. I am also very interested in related topics such as CI/CD, infrastructure, and IaC. I am capable of teamwork and constructive criticism, and I place great importance on high-quality work results. Technically challenging fields do not intimidate me.
