   Jan 2024 — Present · IN

   At Quantiphi, As Senior Developer I focused on transforming backend systems to elevate performance and scalability. I spearheaded the transition from Looker to GraphQL, achieving breakthrough improvements in data retrieval speed and flexibility. I also upgraded core systems, tackling dependency challenges to ensure a seamless, future-ready tech stack.One of my standout contributions was revolutionizing the KYC service backend. I architected and optimized secure, efficient data flows that powered key compliance and fraud prevention measures. By implementing streamlined API integrations, enhancing service orchestration, and scaling data capabilities, I elevated the reliability and efficiency of the KYC processes.I also configured cutting-edge Firebase authentication with JWT, ensuring airtight security and data privacy. Additionally, I developed robust unit tests for.NET Core services, reinforcing system integrity and minimizing vulnerabilities.Throughout my role, I ensured that technical documentation was clear, concise, and empowering for stakeholders, transforming complex backend workflows into intuitive guides. My mission was to deliver secure, scalable, and efficient backend solutions that set a new standard of excellence.
