~/about $

cat about.md

I'm a full-stack engineer with backend depth, focused on the kind of systems where correctness, observability, and speed all matter at the same time — financial platforms where a missed edge case becomes a real-world incident.

At Deutsche Bank, I've worked across the Corporate Bank's technology portfolio — shipping experience-layer banking APIs, contributing to internal corporate banking platforms, and now working on dbCIS (Cash Investment Service), DB's corporate liquidity management platform for Money Market Fund investments.

My backend toolkit centers on Java, Spring Boot, Golang, and Python on GCP, with deep practice in microservices, Kafka, and CI/CD pipelines. On the frontend, I've shipped complex UI in React and TypeScript — advanced filtering and search, multi-step approval workflows, reusable design system components, and full E2E coverage with Cypress.

Before DB, I interned at Omist Consultancy where I built meemarathavadhuvar.in — a matrimony platform now serving 3,400+ users — and freelanced on 5+ production websites for NGOs, businesses, and ecommerce clients. I have an MCA from Sardar Patel Institute of Technology, Mumbai (CGPA 9.6/10).

Outside of work, I'm sharpening my data and ML chops — exploring Pandas, Scikit-learn, and applied analytics on financial datasets.
