Hi! I build web projects that work fast, and I test software to ensure it doesn't break. I am a tech-minded freelancer with a strictly practical, engineering-first approach. I don't believe in overcomplicating projects with unnecessary, heavy features, distracting animations, or "boring academic water." My focus is on pure functionality, speed, and clean logic. If you need someone who cuts through the noise and delivers precise results, you are in the right place. PRECISION QA TESTING & UX AUDITS I don't just "click around"; I test like a real user but analyze like an engineer. My testing process is built on finding edge cases, breaking game logic, and ensuring the final product is ready for deployment. Functional & Exploratory Testing: Deep-dive testing for PC games and web applications to find softlocks, progression blockers, and technical failures. Detailed Bug Reporting: I deliver structured, easy-to-read, and actionable QA reports (PDFs, screenshots, video clips) so your developers can fix issues immediately without guessing. UI/UX Consistency: I pay close attention to visual details, stylistic consistency (e.g., pixel-art vs. vector graphics matching), and controller/input mappings. Recent Success: Successfully completed comprehensive pre-release testing for an upcoming Steam puzzle game, identifying UI inconsistencies and verifying edge-case stability. The client praised the clarity of my reports and invited me for their upcoming sequel. FUNCTIONAL FRONT-END WEB DEVELOPMENT As the creator and sole manager of my own functional web platform, I know how to build sites from the ground up. I prioritize performance and user experience over flashy, resource-heavy designs. Core Stack: Clean, semantic HTML5, CSS3, and JavaScript. Speed & Optimization: I prefer to strip away complex, heavy animations to ensure maximum loading speed and a seamless, straightforward user experience. Deployment & Management: Experienced in setting up custom domains, managing FTP/SFTP, and deploying via modern platforms like Netlify. Responsive Design: Ensuring your landing page, portfolio, or static site looks perfect on mobile, tablet, and desktop. THE ENGINEERING MINDSET My approach to tech is grounded in a solid engineering background. As a student at a secondary technical school, my hands-on experience goes beyond software. I actively work with microelectronics, home automation (ESP32, Arduino), and hardware logic. This hardware-level understanding of how systems interact trains my brain to think logically, troubleshoot efficiently, and spot flaws that others might miss. I know how to read technical documentation and translate complex problems into simple solutions. COMMUNICATION & WORK ETHIC I believe that clear communication is half the job. I ask the right questions, provide regular updates, and ensure we are always on the same page. Languages: Fluent in Ukrainian and Czech, with highly proficient English for clear written communication, reporting, and technical documentation. Let’s cut the noise and get your project running perfectly. Send me a message, and let's discuss how my precision and practical skills can help your business or game succeed! TECH STACK & CORE COMPETENCIES: QA & Testing: Manual Testing, Game Testing, PC/Steam Games, Controller Testing, UI/UX Audit, Bug Tracking, QA Reports, Functional Testing, Usability Testing, Edge-case Analysis. Web Development: Front-End Development, Web Design, HTML5, CSS3, JavaScript (Vanilla JS), Responsive Web Design, Static Websites, Landing Pages. Tools & Deployment: Netlify, Web Hosting, FTP/SFTP, Website Redesign, UI Optimization, Cross-Browser Compatibility.
