SDE-1 @Adda247 | Java, Spring Boot, Node | Scalable APIs, Event-Driven Microservices | Immediate Joiner

About

I am a backend engineer working with Java and Spring Boot to build cloud-native backend systems. My work involves designing and maintaining microservices and REST APIs with a focus on scalability, reliability, and performance. I have experience working with event-driven architectures using Kafka, search and retrieval systems using Elasticsearch, caching with Redis, and relational data management using MySQL. I use AWS services for deploying and operating backend applications in production environments. I apply data structure and algorithmic thinking where it directly impacts system performance and efficiency, and I focus on writing maintainable backend code that behaves predictably under load. I am interested in backend and platform roles that involve large-scale APIs, distributed workflows, and production systems with real-world performance constraints.

Software Engineer at Digitize Things Inc., Jun 2026 - Present · 4 mo, Remote

SDE 1 at Adda247, Oct 2024 - May 2026 · 1 yr 8 mos, Gurugram, Backend engineer working on high-scale consumer learning platforms serving 5M+ users, focused on search, subscriptions, content delivery, and system performance. Key Contributions & Impact: •Led backend development of a Reels-style Shorts learning platform, designing home feed APIs, video playback services, and admin tooling; significantly improved short-form content engagement. •Built a centralized Global Search platform using Elasticsearch for Current Affairs, Job Alerts, eBooks, and Quizzes, handling 600K+ weekly queries and reducing average search latency by 40%. •Integrated UPI AutoPay subscription workflows, enabling seamless recurring renewals and directly contributing to improved subscription retention and revenue. •Designed and optimized RESTful microservices using Spring Boot, and introduced Apache Kafka to process millions of in-app events daily, enabling reliable real-time workflows. •Played a key role in transitioning the platform from course-based purchases to monthly subscriptions, ensuring backward compatibility and uninterrupted access for 5M+ learners. •Improved system performance by implementing Redis caching (reducing load times by 30%) and optimizing MySQL & MongoDB schemas with effective indexing strategies (up to 40% faster queries). •Revamped the User Authentication Service to support multi-tenancy, OTP-based mobile login, AES encryption, and 2-device session limits, improving both security and scalability. •Automated large-scale data synchronization using Logstash ETL pipelines, migrating 700K+ records to Elasticsearch with near real-time updates. •Owned features end-to-end across the SDLC from design and implementation to production monitoring and optimization. •Leveraged CI/CD pipelines and Kibana-based log analysis to accelerate debugging, resulting in a 20% reduction in production downtime. •Built internal automation tools for license management and reporting using Google Sheets API, reducing manual operational effort by 80%.
