What I'm looking for

I seek backend roles where I can build scalable, reliable APIs and real-time systems, collaborate in product teams, and grow technically in cloud and search technologies.

I am a backend developer with strong proficiency in Django, Java, and building scalable backend systems for production. I have delivered high-impact features such as group-based expense management, real-time chat using WebSockets, referral engines, and location-based search with Elasticsearch.

During internships at product-focused startups, I optimized systems handling thousands of daily operations — improving API performance, reducing query latency, and automating cron workflows using Celery. I also implemented JWT-based auth and AWS SES OTP flows to strengthen account security and reduce login issues.

I focus on designing efficient, reliable, and user-centric backend solutions that scale; my work has improved settlement accuracy, reduced message latency, increased referral conversions, and cut operational waste in warehouse workflows.
