About Me

Passionate Backend Engineer & System Architect

I'm a Senior Backend Engineer with 5+ years of experience building scalable, high-performance systems. Currently at Instabug, I architect solutions that serve billions of devices and lead engineering teams to deliver enterprise products that drive significant business value.

I specialize in distributed systems, real-time data processing, and performance optimization. My expertise spans from architecting core products and implementing comprehensive monitoring solutions to optimizing system performance and reducing operational costs while maintaining business continuity.

Beyond engineering, I'm committed to social impact through volunteer work with NGOs. I've contributed to educational programs for underprivileged children and refugees in Egypt, and supported medical and development missions in Cape Verde, Africa. Additionally, I handle content creation and social media management for these organizations, helping amplify their mission and reach.
