About

With an M.Sc. in System Design from Amirkabir University of Technology (Tehran Polytechnic), I bridge hardware-level efficiency with cloud-scale architecture. My expertise spans from Linux kernel optimization and embedded systems to architecting hybrid WebRTC/HLS infrastructures serving thousands of concurrent users. My career trajectory showcases a rare combination: deep systems programming expertise coupled with high-level architectural leadership. From optimizing ARM-based IoT devices with custom Yocto distributions to designing sub-100ms high-frequency trading engines, I architect solutions where performance and reliability are non-negotiable. As Head of Software at Capitalino, I led the award-winning AI Hologram project (Best Booth, ITEX 2024) and architected digital investment platforms processing millions in monthly volume. My recent work includes production-grade WebRTC systems with NATS JetStream signaling, serving 1,200+ concurrent users while reducing infrastructure costs by 78%. I believe in leading by example—contributing directly to codebases while orchestrating cross-functional teams. Whether it's building P2P cryptocurrency exchanges, designing atomic OTA update pipelines for 5,000+ IoT devices, or implementing Greedy Knapsack algorithms for optimal trade execution, I deliver systems that scale.
