About

I share daily insights to help developers build scalable, production-grade systems using Java, Spring Boot, Kafka, and emerging GenAI tools. With over a decade of experience in backend engineering, I currently work as a Staff Engineer at Chegg, where I architect distributed systems that serve millions of students. I write and speak about: Java, Spring Boot, Kafka, GraphQL Observability in microservices SQL & NoSQL (MySQL, Oracle, DynamoDB) GenAI in software engineering Frontend integrations with React 🛠 I create content weekly on: LinkedIn: Bite-sized insights, system design, debugging lessons Medium: Deep-dive articles & architecture breakdowns YouTube: Code walkthroughs and visual explainers 🚀 My goal? To help you write better code, design smarter systems, and stay future-ready with AI. 🤝 Open to working together on impactful projects or as a technical consultant in backend, cloud architecture, or GenAI integrations. Let’s connect and build something meaningful.

Designed and led migration of a legacy monolith to a cloud-native microservices architecture serving 10M+ monthly users, reducing request latency by 40% and improving system availability to 99.00%. Partnered with product and business teams to define the technical strategy for a personalized learning platform, directly contributing to a significant increase in user engagement. Drove adoption of a Kafka-based event streaming platform across multiple teams, enabling near real-time processing of millions of student activity events daily. Identified excessive service granularity and led an initiative to consolidate services, resulting in a cleaner architecture, quicker release cycles, and improved observability/dashboarding. Championed the integration of distributed tracing across microservices and Kafka ecosystem, enabling end-to-end request visibility and faster issue resolution. Mentored and coached 10+ engineers, influencing architectural decisions beyond immediate team scope and improving organizational engineering quality. Contributed to the effort to finalise the AI code assistance and PR review tools
