About Praveen Kumar

I am a hands-on Principal Engineer and Architect with 20+ years of experience designing, building, and operating large-scale, cloud-native systems, primarily in the Healthcare domain. I specialize in translating complex business requirements into secure, scalable, and resilient technical solutions, while actively contributing to architecture, coding, and production engineering.My core strength lies in architecting distributed systems and microservices across Microsoft Azure, AWS, and GCP. I have deep expertise in building event-driven and serverless architectures that support mission-critical workloads with high availability, performance, and compliance standards.Beyond traditional cloud architecture, I am actively working with modern AI-driven systems and intelligent platforms. I have experience integrating Generative AI and LLM-based solutions into enterprise applications using tools and services such as:• Azure OpenAI Service• OpenAI APIs (GPT models, embeddings, assistants)• AWS Bedrock• Vector databases and semantic search (e.g, AI Search, embeddings with Cosmos DB)• Retrieval-Augmented Generation (RAG) architectures• Prompt engineering and AI orchestration patterns• AI-powered automation and AIOps solutionsI focus on designing AI-enabled architectures that are secure, compliant, and production-ready — especially in regulated domains like Healthcare.Technically, I remain deeply hands-on across the stack:• Backend engineering using Node.js.NET, and Python• Modern frontend applications using React and Angular• Data architecture with Azure Cosmos DB, SQL Server, and other NoSQL/relational databases• Infrastructure as Code (Terraform, ARM/Bicep)• CI/CD automation and DevSecOps practices• Observability, monitoring, and performance optimizationI am passionate about solving complex scalability and reliability challenges, optimizing system performance, and building platforms that are cloud-native, AI-enabled, and future-ready.In addition to architecture, I actively mentor engineers, review designs and code, establish engineering standards, and drive technical excellence across teams. I strongly believe that impactful architecture is rooted in deep implementation experience and continuous learning.I enjoy working on complex technical problems, modernizing legacy systems, and building intelligent, scalable platforms that create measurable business impact.
