Full Stack Developer at Altimetrik building Citi Bank's GenX payments platform and integrating an enterprise RAG pipeline.

India
Message

At Altimetrik, I develop GenX, a digital payment platform for Citi Bank. I build React.js applications and Python/FastAPI services, and integrated a RAG pipeline that grounds LLM responses in enterprise and payment knowledge.

At 5Data Inc, I built data-intensive frontend and backend features for Pulsora, an ESG analytics SaaS platform. I improved dashboard render performance by 35% for datasets of 10,000+ records.

For Pulsora, I also shipped an LLM-powered PDF auto-fill feature and an ESG Insights Module that generates natural-language compliance summaries. I applied tiered LLM routing to balance accuracy and inference cost.

At KloudPortal, I developed the React.js frontend for Zipinmail, a cloud mailbox SaaS platform, and integrated APIs for mailbox provisioning, document handling, and authentication. I also built Arthwise, a React Native mobile app with real-time trading updates and leaderboards.
