About

Hey! I'm Pavel, a creative 22-year-old who loves building products with code. And when I need to relax, I like to create designs or 3D models.

Currently, I'm a Senior Front-End Engineer at DCC company, accessibility. I contribute to the creation and maintenance of UI components, ensuring our platform meets web accessibility standards and best practices to deliver an inclusive user experience.

In the past, I've had the opportunity to hone my web-development skills—starting with simple React sites and UIs, then moving into security engineering by implementing anti-bot and anti-scraping defenses and writing parsers to probe vulnerabilities. I've built both Node.js/Express backends and React frontends—ultimately specializing in the frontend—and worked in diverse settings, from advertising agencies and large corporations to start-ups and small digital studios. Along the way, I've mentored junior developers and served as a Tech Lead at major companies.

    Co-Founder · Silence Team | Architect
    Together with colleagues, I architected and delivered a private software suite for cryptocurrency arbitrage and large-scale social account monitoring. We built custom parsers for dozens of websites and bypassed advanced bot protections by leveraging unofficial APIs for Twitter, Discord, Outlook, GMX, and others. I led the deployment and configuration of physical servers and personal proxy networks to manage high-volume traffic. Our microservices architecture—initially powered by BullMQ and later RabbitMQ—featured custom integration services and Go-based helper modules. We also maintained a bespoke Storybook UI kit for internal tools.

    Developer · BHZ
    At a fertilizer enterprise with a small 3–4-person dev team, I maintained and modernized legacy systems—rewriting UI in React, migrating JavaScript modules to TypeScript, and rebuilding sites originally done in page-builder tools. I also tweaked Express backends and wore a full-stack hat throughout the project.
