What I'm looking for

I am looking for a challenging role in a dynamic environment that values innovation and collaboration, where I can contribute to impactful projects and continue to grow my skills.

I am an experienced and results-driven Senior Full-Stack Developer with over 12 years of expertise in designing and developing scalable web applications. My specialization in JavaScript and TypeScript, combined with my proficiency in Node.js and React.js, allows me to create enterprise-scale architectures using microservices and event-driven systems. I have a proven track record of leading cross-functional teams, optimizing performance, and delivering robust software in fast-paced, agile environments.

Throughout my career, I have contributed to high-performance financial trading environments, building secure and scalable microservices while mentoring junior developers. My experience includes maintaining and extending white-label broker CRMs and developing modern web and mobile applications with a strong focus on security and user experience. I am passionate about implementing NIST-compliant security practices and ensuring system reliability through proactive monitoring and testing.
