What I'm looking for

I'm looking for remote roles across India or global remote positions, and I'm available for immediate joining.

At Nagarro Enterprise Services, I developed RESTful APIs and optimized service logic and SQL queries for the Sportsbook Application, reducing average API response time from 3 seconds to 800 ms.

I also built and maintained end-to-end automated integration test suites using SpecFlow, increasing test coverage and reducing production defects. I delivered backend features for automated pricing and risk management for B2B and B2C users.

At HANATECH SOLUTIONS PVT. LTD., I designed and implemented RESTful APIs and reusable backend components, including an API Manager and NuGet templates. I contributed to event-driven microservices using RabbitMQ, Redis, and Kubernetes/AKS, and led integration test development and code reviews.

At REFINITIV, I developed a multilingual NLP engine that converted unstructured HTML into structured XML for financial data processing and analytics. I also built a service-oriented automation platform and engineered a multi-format document conversion service using PDFTron.
