Khalid Rizvi Profile

👤 About Me

#

I’m Khalid Rizvi, a hands-on Solutions Architect with over 30 years of experience at the intersection of cloud-native engineering and emerging AI technologies. I specialize in modernizing legacy systems, architecting high-performance cloud platforms, and exploring the frontiers of Generative AI.

My expertise spans three core pillars:

Cloud-Native Systems & Go Engineering: Proven ability to design scalable, resilient systems using AWS and Azure with Go and Java, optimized for concurrency and performance. From microservices and serverless applications to event-driven platforms, I build production-grade architectures that scale.

Generative AI & Applied ML: Passionate about Generative AI and actively exploring its practical applications. I’ve built prototypes with LangChain, OpenAI APIs, and AWS Bedrock, and have kept pace with the rapid evolution of LLMs, safety frameworks, and RAG systems. I’m eager to apply GenAI thoughtfully in modernizing real-world systems.

Legacy Modernization: Led major transformations, converting COBOL and PowerBuilder systems into scalable, secure cloud-native applications. I focus on balancing business continuity with technical innovation to deliver measurable results.

I thrive at the bleeding edge—engineering AI-driven systems, designing cloud-native architectures, and leading modernization efforts with a builder’s mindset.
