About Me

Senior engineer depth, creator energy.

I am currently working as a Senior Member of Technical Staff (SMTS / SDE-3) at Oracle.

Over the last 5+ years, I have built scalable backend systems, microservices, distributed architectures, cloud-native applications, and AI-powered solutions.

I strongly believe that knowledge compounds when shared. This belief drives me to create educational content, mentor aspiring engineers, publish interview experiences, and contribute to open-source projects.
