Sourav Paul

👨‍💻 Sourav is a Senior Lead Software Developer with 12+ years of experience specializing in designing and building highly scalable, event-driven, resilient, and distributed systems that power mission-critical applications.

His work sits at the intersection of clean architecture and engineering rigor—translating complex business requirements into robust, maintainable solutions built to perform reliably at scale. He contributes to the end-to-end design and implementation of microservices, with a strong focus on orchestration-based architectures, distributed systems, and resilient service interactions.

🏗️ Architecture & System Design

▪️ Microservices & Orchestrator Architecture: SAGA, CQRS, Event Sourcing, Outbox, Sidecar, and Materialized View patterns—designing service interactions that are fault-tolerant, scalable, and operationally sound.
▪️ Distributed Systems: Designing systems with a focus on scalability, resilience, fault tolerance, availability, and eventual consistency.
▪️ Event-Driven Architecture: Building high-throughput, loosely coupled systems using Kafka for asynchronous and decoupled service communication.
▪️ API Design: Designing and integrating APIs across REST, gRPC, GraphQL, WebSocket, and SOAP.

🎯 Sourav helps professionals prepare for coding interviews and system design interviews for FAANG and other leading product-based companies.

💡 He has extensive experience solving problems across LeetCode, HackerRank, CodeChef, Codeforces, and CodeSignal, with a strong focus on problem-solving techniques, algorithmic thinking, and time and space complexity analysis.
