Experience

Plot Finder

An application that assists users to find a plot. It scraps several websites with plots, automatically groups the same offers, and shows them to the end-user. Users can add offers, favorites, and notes. I wrote the code using .NET Core, Angular 11, and Microsoft SQL Server.

Smart Home Application

https://github.com/arkadiuszneuman/HomeAutomationScript

A microservice-based application that uses a home assistant that controls IoT devices at a home. I developed an application that can automate blinds, light bulbs, TV, and more. For example, when I am coming home and it is dark outside my garden lights switch on). I wrote drivers in C++ for ESP 8266 to control my blinds and my stair LEDs. I can also control every device by voice thanks to the Google Home speaker. The devices and my microservices are communicating by REST, RabbitMQ, and MQTT protocols. I also added Grafana to visualize charts and the ELK stack to show the application logs.

Bank Analizer

https://github.com/arkadiuszneuman/BankAnalizer

An application that helps to manage expenses. It can automatically import data from several Polish banks. It groups expenses by text or by the bank account to various groups such as "home expenses", "car expenses", "health" etc. It can show charts so users can see what the money was spent on. I wrote the code using .NET Core and React.
