About

Architecting resilient, secure, and scalable distributed systems and IoT platforms. Specializing in high-throughput enterprise platforms, cloud-native architectures, and AI-native engineering systems that support millions of devices and massive streaming workloads. Driving the execution of complex technical solutions requires a strict focus on system reliability, clean service boundaries, and observable architecture. Engineering experience spans design and delivery of distributed systems that process over 500K managed devices and sustain throughputs exceeding 50K messages per second. Key areas of engineering practice: - Distributed Systems Architecture: Scaling event-driven and reactive platforms with structured backpressure, loose coupling, and reliable message brokers. Expert in implementing fault-tolerant microservices that ensure eventual consistency across high-volume streams. - Platform Security and Hardening: Integrating secure-by-default design principles into standard development practices. Proven history of resolving major security backlogs, establishing automated static and dynamic analysis gates, and securing cloud deployments. - Modern DevOps and Automation: Structuring declarative infrastructure configurations and cloud automation pipelines that isolate environments and enable low-risk deployments. - Technical Leadership and Team Mentoring: Guiding technical roadmaps, leading high-impact architectural review sessions, and training software teams to adopt cloud-native design standards. - AI-Native Platform Strategy: Transitioning modern runtime engines to leverage Spec-Driven Development, RAG architectures, and multi-agent workflows to increase delivery speeds. Combining strategic vision with hands-on systems engineering, the primary focus remains on reducing structural complexity while expanding absolute capacity. email: shariksaigal@gmail.com
