Arun Giri — Senior Software Engineer

Hi, I'm Arun Kumar Giri – a Senior Software Engineer with 4.5+ years of hands-on experience building scalable, user-centric solutions at Optum (UnitedHealth Group), a global leader in healthcare technology. I specialize in full-stack development, bridging modern frontend technologies (React.js, React Native, Next.js, Redux) with robust backend microservices (Java Spring Boot) and cloud-native infrastructure (Docker, Kubernetes, CI/CD with GitHub Actions). My work focuses on delivering high-impact features that directly improve patient and member experiences in one of the world’s largest healthcare ecosystems. Key highlights from my journey: Led the full-stack modernization of Optum’s core Web Rx pharmacy and prescription platform, migrating to Next.js + Spring Boot with containerization – resulting in ~30% performance gains. Spearheaded the end-to-end integration of the entire pharmacy ecosystem (~20 new pages and flows) into the UHC mobile app using React Native, bringing previously web-only capabilities like medicine delivery, order tracking, and prescription management to over 1 million mobile users across all lines of business. Architected critical user flows such as Home Delivery Pharmacy and U-Card digital insurance card generation, while establishing streamlined testing and DevOps practices that boosted team efficiency and deployment velocity. Beyond production work, I’m passionate about leveraging emerging technologies. I designed and built Sprint KickStarter, an AI-powered productivity tool using Retrieval-Augmented Generation (RAG), LLMs, and FAISS vector database to parse sprint stories and provide intelligent, context-aware implementation suggestions – earning recognition as an Optum Consumer Innovation Expo Honoree. I thrive in collaborative, fast-paced environments where engineering excellence meets real-world impact. Whether modernizing legacy systems, scaling mobile experiences for millions, or exploring GenAI applications, I’m driven by creating solutions that make healthcare more accessible and efficient. Always open to connecting with fellow engineers, product leaders, and innovators in healthcare tech, full-stack development, and AI-driven tools. Let’s chat!
