About Shashikant Kummar
Lead Engineer with 6+ years of experience designing and optimizing performance-critical systems across embedded firmware and scalable software platforms.At Samsung Electronics, I lead architecture and performance initiatives for production systems operating under strict latency and reliability constraints. I drive end-to-end ownership — from system design and architectural decisions to optimization, debugging, and delivery — improving throughput, reducing latency, and increasing system stability at scale.Previously at Qualcomm, I worked on 5G PHY/Modem software, debugging low-level firmware issues in real-time systems, optimizing memory usage, and resolving latency bottlenecks across performance-critical paths.Beyond enterprise systems, I architected and launched a full-stack Android-based food delivery platform (ZustEat), designing scalable backend workflows, optimizing database access patterns, and implementing real-time order state management.Strong foundation in: • Data Structures & Algorithms (300+ problems solved)• System Design & Distributed Systems• Low-latency and high-throughput systems• Memory and performance optimizationI’m interested in building large-scale, high-impact systems where architecture, scalability, and engineering rigor matter.ojects.
