About

I'm a Software Engineer with ~4 years of experience designing, developing, and maintaining scalable backend systems. I specialize in building reliable and high-performance services, primarily using Java, Spring Boot, and REST APIs, and have also worked across the stack when needed. My experience spans end-to-end product development — from gathering requirements and low-level design to deployment and monitoring. I’ve worked closely with cross-functional teams in fast-paced environments, taking ownership of features and delivering impact under tight timelines. Key areas of strength include: • Backend development using Java, Spring Boot • RESTful APIs, Microservices architecture • SQL and NoSQL databases (MySQL, MongoDB, Redis) • Messaging queues (Kafka, RabbitMQ) • System design and performance optimization • CI/CD, Docker, Git, and cloud deployments (AWS) I’m also passionate about writing clean, maintainable code and continuously improving system design.

Software Engineer

Jul 2021 – Jan 2023 · 1 yr 6 mos · Pune, Maharashtra, India

● Demonstrated proficiency in technologies like SpringBoot (Java), SQL, ReactJS and Apache Pulsar.
● As a key contributor to the team, I play a vital role in overseeing the functionality of the entire event
lifecycle. This involves handling adjustment data reception from the upstream, event generation, facilitating
event resolution, and ensuring the timely closure of each event.
● Successfully designed, implemented, integrated, and tested the end-to-end functionality of a system slated
for decommissioning, seamlessly incorporating it into our application.
● Developed a robust system for efficient data notification and transfer from our application to another data
manager using Pulsar topics. Implemented database models along with end-to-end REST APIs to
consume, transform, store, and deliver data to consumers seamlessly.
● Skillfully integrated Zipkin into our application to effectively monitor service level performance.
● Identified performance bottlenecks within the application and proactively addressed them. Implemented
indexes in existing tables and utilised CompletableFuture API to introduce multithreading functionality,
resulting in double throughput of REST services.
● Successfully led a proof of concept (POC) on Elasticsearch, achieving improvement from approximately
1.5 minutes to a mere 30 seconds.
● Undertook an extensive code cleanup and refactoring effort, ensuring a maintainable and organised
codebase, promoting future scalability and maintainability.
● Proficiently managed application deployment and promptly provided production support.
● Conducted a comprehensive training session within the organisation, covering the implementation of
Lambdas and Streams API in Java.
