Project details
UN Engineer and Microsoft Certified Professional Zeeshan offers comprehensive tutoring in advanced System Design, equipping students with a deep understanding of distributed systems and database architectures.
With 6+ years of experience, Zeeshan covers a wide range of topics, including causal reads, conflict resolution, linearizability, and mesh architectures. His expertise extends to coordination services (e.g., ZooKeeper), distributed caching, consistency and database models, ETL pipelines, and leader election protocols.
Zeeshan teaches core principles in network partitioning, Byzantine faults, fault, tolerance, SLAs, and fault tolerance complexities.
Students learn indexing methods like LSM trees, B-trees, and hash-based indexing, as well as caching strategies, load balancing, geo-fencing, and location-based services.
Zeeshan provides insight into API models, communication protocols, distributed file systems, and tools for code security and analysis. Dedicated to practical application, he helps students master strategies for fault management, cost efficiency, security, and resilience in system design.
