About Me

From sysadmin to senior React developer — the longer story.

I started in tech as a system administrator, managing servers and networks. My direction changed when I wrote a script to parse a phone number database for a marketing campaign — that small thing showed me how satisfying it is to solve problems through code. I moved into web development, started with Vue.js and D3.js, then settled on React for its scalability on complex projects. I haven't looked back.

Since then I've worked across startups and larger companies — in-office and remote, including US-based teams. I care about TypeScript, testing, and CI/CD not as checkboxes but because they make complex codebases actually manageable. I focus on doing things right, not just fast.

My Philosophy

Pragmatic Approach

Select the best tool for the task while staying open to improvements and adaptability.

Quality Focus

Prioritize quality and maintainability in complex software, keeping complexity to a minimum.

DevOps Mindset

Automate repetitive tasks — CI/CD, linting, packaging, and testing — so the team ships faster.

Continuous Learning

Technology evolves rapidly, and so do I. Always exploring new tools and frameworks to stay sharp.

  • TypeScript & component architecture
  • Performance & Core Web Vitals
  • Unit, integration & E2E testing
