πŸš€ Who I Am

I'm a Senior Engineer with 6+ years of international experience building scalable, cloud-native systemsβ€”from data lakehouses to high-performance backends. I've worked with startups and enterprises in Dubai, Qatar, and Iran, in remote, hybrid, and on-site setups, and I thrive in cross-functional, distributed teams.

I combine data engineering and software engineering: I design data architectures that power analytics and AI, and I build the backend services that serve them. Whether it's reducing data latency by 40%, cutting query time by 50%, or processing millions of records in real time, I focus on impact, reliability, and clean architecture.
