Metereological Station

The IoT Meteorological Station is an end-to-end environmental monitoring system that collects real-time data using
embedded sensors (BME680, BH1750, DS18B20) connected to a Raspberry Pi Pico W. The device firmware, written in
MicroPython, transmits sensor data via MQTT to a backend service, where it is processed, stored, and exposed through
a REST API. The data is visualized through a responsive React-based dashboard, enabling real-time monitoring and
remote device interaction.

Tech Stack: MicroPython, Raspberry Pi Pico W, MQTT, Node.js, Express.js, React, TypeScript, Vite, Tailwind CSS, Docker,
REST API.

EquiPay

EquiPay is a shared group finance application built for the Tatra Bank Hackathon. The app allows users to create
shared wallets, invite members, connect bank accounts through a PSD2/open banking flow, track group balances, split
payments, manage virtual cards, and analyze spending history. The backend handles JWT authentication, email
verification, PIN login, refresh token rotation, Redis-based rate limiting, PostgreSQL data storage, transaction splitting
logic, Tatra Bank PSD2 integration, and AI-powered expense parsing from voice, chat, camera, and receipt images.
Tech Stack: Kotlin, Ktor, PostgreSQL, Redis, Exposed ORM, HikariCP, JWT, BCrypt, REST API, Docker, Render, Tatra Bank
