About

A passionate database engineer with a deep fascination for crafting efficient and robust data solutions. With 13 years of hands-on experience, I thrive in the dynamic world of databases, turning complex data challenges into elegant, high-performance systems. Over the years, I've honed my expertise in designing, implementing, and optimizing databases that power applications and streamline data workflows. My toolkit includes proficiency in Oracle databases, Real Application Clusters, Database replication technologies (Goldengate), NoSQL, Python, Shell scripting.

When I'm not immersed in databases and code, you'll find me watching football. I proudly wear my heart on my sleeve as an ardent Chelsea FC fan. From Stamford Bridge to the grandest stages of European football, I’ve followed the Blues’ journey with unwavering devotion.Being a Chelsea fan isn’t just about the wins and the titles – it’s about the camaraderie, the roller-coaster emotions, and the shared experiences with fellow fans. Whether it’s the exhilaration of a last-minute goal, the nervous anticipation before a crucial match, or the collective pride in the club’s rich history, every moment is etched into my football-loving soul.
