What I'm looking for

I seek backend roles where I can build scalable APIs, improve system performance, mentor teams, and work with modern Node.js stacks and cloud infrastructure.

I am a backend engineer with over 4 years of professional experience focused on Node.js, NestJS, and Express.js, building scalable APIs and architecting efficient systems for high-traffic applications.

At JABCOMP I developed secure backend APIs, implemented role-based access control with JWT, and integrated Firebase Cloud Messaging for real-time notifications while optimizing complex MySQL queries using Sequelize.

Previously at O3 Interfaces I led backend development for a SaaS platform, integrated Stripe, RabbitMQ, and ClickHouse, conducted API performance testing, and mentored junior developers to maintain code quality and scalability.

I prioritize robust, maintainable code and enjoy solving complex backend challenges, improving performance, and delivering production-ready systems that enhance user experience and operational efficiency.
