More than just code — I architect scalable systems.
With over 7 years of experience, I specialize in building enterprise-grade web applications and AI-powered solutions
I've led engineering initiatives and mentored developers while delivering high-performance platforms for investment management, eCommerce, and community platforms. My focus is always on scalable architecture, system design, and performance optimization.
Whether it's integrating RAG pipelines with LLMs, orchestrating microservices, or optimizing database schemas, I ensure that the applications I build are robust, secure, and ready to handle large user bases.
