Frontend Developer at Superfund Technologies who built a cryptocurrency trading platform’s admin system from scratch.
PolandWhat I'm looking for
At Superfund Technologies, I architected and built a cryptocurrency trading platform’s admin website from scratch, including real-time market data visualization, trade monitoring, and user management tools.
I implemented Jotai for state management and used Cypress and Playwright to maintain code quality, reaching 90%+ test coverage on critical components. I also contributed to the companion React Native app, including price alerts, portfolio management, and biometric authentication.
At PowerIt, I built N8N automation workflows for client research and lead generation, using Claude to help design workflows, generate code, and speed up research and reporting. I also developed client-facing websites and contributed frontend work to the company’s Vue-based application.
Most recently, at BGaming, I worked on casino games from pre-launch development through post-launch support, monitoring live games and shipping fixes and feature updates. I’m available for remote or hybrid roles across European time zones.
