About

Professional summary

I am a Full Stack Software Engineer with 6 years of experience building production systems with TypeScript, Node.js, NestJS, Next.js, React, and PostgreSQL.

I have worked on high-scale products, including microservices serving millions of users, platform migrations with zero downtime, and backend systems that support complex business operations.

I enjoy owning features end to end, from technical design and implementation to testing, release, and documentation. I also like improving team workflows through automation, AI-assisted development, and clearer engineering processes.

I founded MarbleOX, an AI-powered ERP and quoting SaaS, where I took the product from zero to paying customers and continued to shape both the technical architecture and business outcomes.

I have experience collaborating with US and global teams in English on a daily basis, mentoring junior developers, and leading frontend and full-stack delivery in remote environments.

I am open to opportunities where I can contribute to scalable product development, strong engineering practices, and modern web architecture.
