SaturationMap: Tool for Geocachers
04/2026
A browser-based map tool for geocachers, currently in development. Users can add cache locations manually by placing them on the map, or import existing caches in bulk via CSV file. Each cache is displayed with its 161-meter exclusion radius, making it easy to spot available gaps for new hides. Cache details can be edited or removed at any time directly from the map. Caches can also be exported as a CSV file for use elsewhere. In addition to caches, users can place placeholder markers on the map to plan or reserve potential spots.

Cache data is stored locally in the browser using IndexedDB. Since browsers can purge this storage unexpectedly, the app also offers a more permanent option: with a single button click, users can download a self-contained clone of the map as a standalone HTML file, with all cache data hardcoded directly into it. This cloned file works independently and keeps data safe from browser storage clearing.

Project is still in active development and some features are incomplete. Currently works best on desktop browsers.

Buddy Helpperi: Elderly Care Companion Robot
04/2026
As part of a Creative Innovation Process course at Oulu University of Applied Sciences, our two-member team explored applications for the Blue Frog Robotics' Buddy robot, a tablet-faced companion robot, in the context of elderly healthcare.

The Buddy robot ran on Android operating system and my main contribution was an Android application written in Kotlin. Since access to the physical robot was limited, we developed an Android tablet application that simulated the robot's face and logic as a backup solution.

The app displayed an animated face on the screen to mimic the Buddy robot's appearance. Face was made using Google Gemini Nano Banana and animated manually using LottieFiles.

To make the application have conversations with the user, we used OpenAI's Whisper API and Text-to-Speech API to create a natural conversation flow. Wake word detection was handled locally on the tablet using Vosk, an offline speech recognition API.

We also integrated an alert system that activates when the user sends a distress signal (e.g. "Hey Buddy, I need help"). The alert is pushed to a Firebase Firestore backend and synced in real time with a companion mobile app built for healthcare professionals.

In addition to application development, we conducted user research and usability testing. At the end of the course, we pitched our idea in a Dragons' Den style presentation. Out of 13 teams, we were awarded 3rd place.

Personal Project UI/UX TypeScript Cloudflare

Rautiai.net: Personal Website
04/2026
This is my personal website, built to showcase my projects and skills. It was created as a static, one-page website using HTML, CSS, and TypeScript, hosted on Cloudflare Pages with continuous deployment from GitHub.

The website is fully responsive and designed with a dark theme, minimal layout, and attention to detail in both design and performance.
Bachelor's Thesis Thread IoT C Cloudflare

Design and Implementation of a Modular Thread-Based Sensor Platform with Cloud Integration
05/2025
The goal of this thesis was to design and implement a sensor platform that utilizes a Thread network for communication within a local network and then connects to the internet to transmit its data. The system consists of three core components: the sensor platform, the Thread Border Router, and the web application.

The sensor platform was built using an ESP32-H2 development board and environmental sensors, including temperature and humidity sensors. The platform was designed to be modular, allowing for easy addition or removal of sensors as needed.

The Thread Border Router was implemented using an ESP Thread Border Router from Espressif. It served as a bridge between the Thread network and the internet.

The web application was developed using Cloudflare Pages and Workers, providing a real-time interface for monitoring sensor data, visualizing historical trends, and configuring measurement intervals.

Development of a Simple Automated Vehicle and Its Safety Analysis
03/2024
This project was part of my student exchange in Sendai, Japan. It involved the development of a simple automated vehicle and a comprehensive safety analysis.

The robot was a four-wheeled vehicle that used IR sensors and algorithms to navigate autonomously, avoiding obstacles. Safety analysis was done to identify potential risks linked to the vehicle and sensors used in the project.

The project was built using Python and the Robot Operating System (ROS), with Linux and command line tools used heavily throughout development.

Development of a Simple Environmental Monitor
05/2023
This project involved designing a PCB for a simple environmental monitor built around the AVR ATmega328P microcontroller. I handled the full process from schematic design and PCB layout to assembly and firmware programming in C++. The board included a temperature sensor, humidity sensor, and an LCD display.

Bank Simul: ATM Banking Simulation
12/2022
Bank Simul was a course project simulating an ATM machine, covering UI/UX design, database design, and full-stack development. Users could log in, deposit and withdraw funds, and view their transaction history.

The frontend was built using the Qt framework and the backend was implemented with Node.js and SQL, handling data storage and business logic.
