About

As a Senior Integration Engineer with 8+ years of experience in Payment Gateway and Neo Banking domains, I specialize in building scalable API/SDK integrations and driving seamless system interoperability. I develop demo web and mobile applications (e.g., Subscription Demo App, PG Mobile SDK samples) to accelerate merchant onboarding and adoption. I own and enhance official GitHub repositories and integration documentation, contributing to a 40% reduction in integration time through developer tools like Cashfree DevStudio. I consistently deliver high-quality merchant support with a 96% CSAT, improving developer experience and integration success rates. Leveraging AI, including LLMs such as Codex and Claude, I build automation workflows and agentic AI-based personal projects to optimize documentation, support, and integration processes. Focused on delivering scalable, developer-first, AI-enabled solutions that enhance efficiency, reliability, and overall merchant experience.
