About me

I'm an Electrical & Electronics Engineering graduate from VSSUT, Burla, with a diverse background in Backend API development and Conversational AI. With nearly 4 years of professional experience, I am a skilled Backend Developer showcasing successful leadership in designing and developing scalable enterprise applications. My expertise includes NodeJS, Express, SQL, NoSQL, AWS, and Azure. I have led and managed multiple teams and projects, utilizing my proficiency in various frameworks to prioritize speed and precision. I am eager to contribute as a Software Development Engineer (SDE) or Backend Developer, leveraging my leadership experience.

In my current role as a Technology Analyst at Infosys Ltd. in Bhubaneswar, I serve as an Offshore Team Lead for a retail MNC's backend team. I drive end-to-end backend development, system support, and root cause analysis (RCA) processes. I enhanced the logic for self-checkout and delivery order services, resulting in reduced API response times. I revamped the low-level design and third-party integration services to streamline inventory synchronization and order settlements, reducing sync errors by 20%. I optimized serverless APIs using AWS Lambda and MongoDB through improved code quality, caching mechanisms, and event-driven architecture. I also configured comprehensive logging, alerting, and monitoring dashboards using New Relic, Mixpanel, and AWS CloudWatch. Additionally, I refactored backend frameworks to enable a smooth API migration from Lambdas to ECS, achieving a 50% improvement in response time and 30% cost savings by addressing cold starts, concurrency, and scalability.

At TCS, I served as Offshore Technical Lead for a UK-based healthcare MNC. I led the Intelligent Automations team, transforming a monolithic NodeJS Chatbot Platform into microservices, achieving notable cost savings. We supported 9 frontend platforms using the Adapter Design Pattern. I also led CI/CD adoption with Docker and AKS, and optimized SQL queries and API/database performance. I mentored a team of 4–5 backend developers during this time.

I’m an intermediate DSA problem solver with strong SQL skills. I've contributed to enhanced chatbot and voicebot systems, facilitated client-vendor communication, and conducted thorough code reviews and testing. Beyond my role, I explore IoT platforms like Blynk and IFTTT, and have hands-on experience in home automation, 3D printing, robotics, Matlab-Simulink, and embedded systems.
