About

👋 Hi! I’m Arunika, an SDE 2 at Microsoft with a strong background in building scalable, production-grade systems in Java, Spring Boot, and Kafka. 🚀 At Microsoft, I designed and delivered “Common Phrases” and camera functionality for Bing Translate, impacting 130M+ DAU, while leading initiatives to improve developer efficiency using Gen AI tooling and metric improvement frameworks. I enjoy taking ownership from HLD, LLD, to rollout while maintaining a high bar for clean code and user impact. ⚡ Previously at Goldman Sachs, I engineered Kafka microservices, optimized async Kafka Streams to reduce latency by 25%, and designed memory-efficient Java services to handle high-throughput financial systems, achieving a 5x improvement in client onboarding workflows. 📈 I am passionate about system design, clean architecture, and performance optimization, with experience in reducing heap usage by 60%, building reconciliation pipelines, and automating data cleaning pipelines for onboarding low-resource languages. 🛠 Tech I work with: Java, Spring Boot, Kafka, Python, C#, Terraform, MySQL, Azure DevOps, Linux, LLMs, System Design. 🎓 B.Tech, Computer Science, IIT Patna (GPA: 9.43/10) 📚 Outside of work, I enjoy writing on Medium about technical concepts, contributing to my GitHub, and mentoring peers on clean system design and backend interview prep.
