About Abhishek K.

Software engineer with 9+ years building scalable systems across the full stack, with deep expertise in backend architecture and distributed systems. Currently at Amazon as SDE II, where I\'ve design event-driven systems using AWS (SQS, SNS, Lambda) and Java.I specialize in the backend layer - architecting RESTful and GraphQL APIs, designing message-driven systems, optimizing database performance, and building resilient microservices. My fullstack foundation allows me to understand the complete data flow from user interaction to backend processing, ensuring cohesive system design.At Amazon, I lead technical design reviews for critical features, mentor engineers on distributed systems patterns, and bridge frontend-backend collaboration to deliver end-to-end solutions. Previously built WebGL visualization tools and analytics dashboards, giving me a strong understanding of how backend systems serve frontend needs.Core strengths: Java, Spring Boot, AWS (Lambda, SQS, SNS), GraphQL, distributed systems, event-driven architecture, with working knowledge of React and modern frontend frameworks.I\'m passionate about solving complex architectural challenges - whether it\'s designing fault-tolerant backend systems, optimizing API performance, or ensuring seamless integration across the stack.
