Software Engineer at Pixie

October 1, 2025 - Present

Built and shipped full-stack end-to-end features including FastAPI backend services, MongoDB data models, and React/Next.js frontends for a product that scaled from 300 to 10,000+ users. Owned features end-to-end—from API contract design through deployment and UI—using user feedback across state management, backend integration, and frontend implementation. Designed REST APIs and shared backend business logic in FastAPI with consistent validation and data contracts as the user base grew ~33x. Worked in agile/scrum cycles (sprint planning, code review, release management) and iterated quickly using real usage data.

Software Developer at Digi 9 Reach Pvt. Ltd.

August 1, 2023 - September 30, 2025

Built full-stack production features with React.js, Next.js, and TypeScript and REST APIs for a system supporting 10,000+ users. Owned client-server integration end-to-end and designed/implemented a microservice-based backend in Node.js for loan/EMI management with REST API contracts and normalized MySQL schema for transaction persistence. Created a reusable component library (React, TypeScript, Tailwind CSS) adopted across 5+ internal dashboards, reducing new feature development time by ~30%. Followed CI/CD with Docker and GitHub Actions and wrote unit tests (TDD, Jest) as part of agile/scrum workflows to improve code review and release cadence.
