About me

I am a dedicated and driven full-stack software engineer with specialized skills in web development. I have extensive experience building industrial web applications from scratch to production for a variety of industries including healthcare, internet marketing, entertainment, live streaming, and blockchain/web3. I have a special passion for OpenAI/ChatGPT and GPT variants as well as other AI services, and I possess rich experience in integrating these services to build intelligent platforms. Over the past six years, I have been working on remote teams and consider myself a good team player.

Throughout my career, I have developed expertise in both front-end and back-end technologies, including JavaScript, TypeScript, React, Vue, Node.js, Python frameworks, and cloud services such as AWS and GCP. I enjoy solving complex problems and designing scalable, efficient systems. My recent projects have involved Web3 integration, blockchain wallet connections, and multi-chain support, showcasing my adaptability to emerging technologies.

I have a strong background in cybersecurity applications, having built secure web apps with React and integrated GraphQL APIs. I am comfortable working in agile environments, collaborating with management to prioritize needs, resolve conflicts, and develop content criteria. I am also experienced in converting mockups into interactive websites with animations and responsive designs.

My education includes two bachelor’s degrees in Computer Science from Coimbra University in Portugal and the State Flight Academy of Ukraine. These programs have strengthened my ability to learn quickly, work hard in demanding environments, and succeed internationally. I am fluent in English, Ukrainian, and Portuguese, which helps me communicate effectively in diverse teams.

I am certified in Front End Web Development and hold an AWS Certified DevOps Engineer – Professional certification. I have a proven track record of increasing API efficiency by 30%, reducing load times by 45%, improving project delivery rates by 25%, and developing cybersecurity applications with high user satisfaction. I am eager to continue leveraging my skills to build innovative AI-driven platforms and contribute to cutting-edge projects.
