Hello and welcome to my portfolio! My name is Roope and I am a bachelor of engineering. I am currently working as a junior system specialist at CSC since June 2022, where I am responsible for maintaining the Puhti, Mahti and LUMI supercomputers. With a background in engineering and a passion for technology, I am excited to share some of my projects and experiences with you. Thank you for visiting my portfolio!
I developed a temperature and humidity
monitoring program in Rust that measures the
environmental conditions of my room every
minute.
The program utilizes a DHT22 sensor connected to
a Raspberry Pi, and the readings are logged in
real-time to a MariaDB database.
To ensure accurate timing, I have set up a cron
job that triggers the program every minute. The
collected data is then visualized using Grafana,
providing insightful graphs and dashboards for
easy monitoring.
I am fortunate enough to be responsible for the
networking at home.
Currently I have set up a OPNSense box from a
decommissioned computer I had lying around. I
added an Intel I350-T2 NIC to have the necessary
two GbE ports.
With OPNSense handling the routing, I have set up
WiFi access points around the house running
OpenWRT to extend the coverage for all wireless
devices as well.
I have set up a live feed of my cat's box she
likes to sleep in using a Raspberry Pi and an
old webcam I had lying around.
The feed is hosted on a Raspberry Pi 3B+ running
Motion and an Nginx reverse-proxy to provide
access from the internet.
The feed from Motion is embedded in a static
HTML as an image which updates 10 times per
second.
This online portfolio is hosted on a
self-customized, bootstrap-based template
running in a Nginx container on an Unraid
machine. To ensure secure browsing for users,
connections are tunneled via Cloudflare.
The container running this website is set up
with a github CI/CD workflow, so whenever I push
changes to the repo the container is
automatically updated.
This helps me keep the site up-to-date and
secure.
I developed an innovative mobile application that provided users with information about various statues and points of interest in the city of Kouvola. The app utilized QR-code scanning technology, allowing users to simply scan a code with their device's camera to access information about a particular location. The app was created using a combination of Unity, Vuforia, and Blender, with 3D models rendered in the latter. The app was released on the Google Play Store. Unfortunately, it has since been taken down.

The device was programmed in C and used a GSM module to receive and interpret text messages. Depending on the state of a relay, the relay would be turned on or off in response to a text message. To prevent the coffee maker from being left on for extended periods of time, the relay would automatically turn off after a certain amount of time had passed.

I took charge of configuring and maintaining the server, and have been successfully keeping it up and running for over three years. This server has also been migrated from the cloud instance to a docker container on my Unraid machine.

During my trainee role as an IT administrator at CSC, I gained valuable experience in maintaining and troubleshooting computer systems. Most of my experience during this period was with Mahti and Puhti supercomputers.
As an intern at Tieto-Oskari, I worked on software development projects and gained valuable experience in the field.
During my internship at KajaPro, I gained experience in both software development and web development.
I started as a temporary worker at Kymen Seudun Osuuskauppa, where I was responsible for maintaining cleanliness in the restaurant. Later, I was offered a longer contract and took on additional responsibilities such as cooking and customer service duties.
As a ride operator at Tykkimäen Vapaa-aikakeskus, I was responsible for operating amusement park rides and providing excellent customer service to park visitors.
I graduated as a Bachelor of Engineering in Computer Sciences, with a specialization in Embedded Systems, at Kajaani University of Applied Sciences.
I received my diploma in Information & Communications Technology from Kouvola Region Vocational College, with a specialization in game development. My GPA for this program was 2.82.
Having a passion for video games my entire life, I've
noticed lately that I've become more interested in
what's going on behind the scenes, rather than actually
playing the games. This combined with another passion in
my life, hardware, has led me into pursuing an
engineer's degree in computer sciences.
I also like sports, finnish baseball to be precise.
Here are some pictures of my personal administrator, Muru.
