Full-stack student developer. I build restaurant software from the counter side: POS, websites, and the APIs behind them.
I'm a second-year Software Development and Entrepreneurship student at Mainor University in Tallinn. I build full-stack projects end to end, from the database schema to the screen someone taps during service.
Alongside my studies I help run my family's restaurant business, VaishnaviInvest OÜ. That operational side shapes the software: billing_pos and the Bella's Café & Grill site were built against the realities of a working restaurant, not a spec.

A full-stack point-of-sale system for a working restaurant: orders, billing and end-of-day totals. FastAPI serves the API, Next.js runs the front of house, PostgreSQL holds every order.
Kasa
An Electron desktop prototype of the POS, packaged to run as a native till app at the counter.
Solo build: schema, API, UI
Family restaurant operations
The restaurant's public website, rebuilt from scratch as a typed Next.js app: menu, opening hours and location, fast on a phone in the street.
Rebuild: design and development
Plans one trip across several modes of transport and compares the options side by side. Built as my submission for the Bolt Graduate Programme.
Solo submission, end to end
Courses, students and enrolments modelled in plain Java around SOLID: narrow interfaces, injected dependencies, one responsibility per class. JUnit 5 covers the domain rules.
Design and implementation
Structured Java problem-solving repos, organised by pattern. Each solution ships with JUnit 5 tests that pin down the edge cases.
