Hey, I'm Aarno!
I like solving difficult problems with
beautiful solutions.
I'm a technical problem solver and solution designer, with experience in the software and EV industry.
I enjoy adventuring in the mountains, skiing on snow, and surfing the oceans. I also love good music, great company, and tasty food.
Background
Virta Ltd
Junior Technical Solution Consultant
May 2025-Aug 2025
I continued working at Virta for another summer, this time as a junior. I spent most of my summer on a software development project for the Pricing team, while also working on tasks like roaming integrations and testing.
During the summer, I built internal full-stack tools using React, TypeScript, PHP, GraphQL, and Laravel, deploying via Kubernetes and AWS. I delivered automation solutions that streamlined customer migration workflows across pricing systems.
I got to contribute to all phases of the software development life-cycle, from discovery and requirements analysis through design, development, and testing. Working on these topics with seasoned software engineers, architects, and testers was a very eye-opening experience, leaving me hungry for more.
Technical Solution Consultant Trainee
May 2024-Apr 2025
I worked as a trainee at Virta Ltd for a year, helping the company to succeed in developing their EV charging platform, and helping gain large multinational customers.
My tasks included mainly roaming integrations (OCPI, Hubject), charging hardware integration and testing (OCPP), and pricing-system migrations. Additionally, I also led technical requirement analysis and customer consultations to define solutions aligned with Virta’s product strategy.
Aalto University
Master's student
Sep 2024-present
Pursuing a Master's Degree in Human-Computer Interaction at the School of Science. Studying topics such as Interactive AI, Machine Learning, Deep Learning, User-Interfaces, User-Centered Design, and Service Design.
I have also worked as a Research Assistant (Department of Applied Physics), building fusion and plasma physics research tools with Python, and as a Teaching Assistant (Department of Computer Science), teaching basics programming with Scala.
Barchelor's student
Sep 2021-Jun 2024
I started my university journey by studying a bachelor's degree in Applied Physics. I did not no exactly what I wanted to pursue, so I decided to challenge myself in the subjects I enjoyed the most, namely physics, mathematics, and programming.
During the three years of studying physics, I studied the most mathematics and programming I could fit in my studies, and eventually ended up minoring in Computer Science. This lead me to continue with a master's degree in Computer Science.
Instituto Superior Técnico
Exchange studies
Sep 2025-Jan 2026
I decided to take a break from studying at Aalto, and ventured off to Instituto Superior Técnico in Lisbon for half-a-year of exchange studies. Here, I am studying topics such as Data Analysis and Integration, Software Arcitechture, and Software Security.
Outside of school, I spend a lot of time in the water, surfing, as well as exploring the city and local culture.
Projects
My portfolio
This website contains my portfolio, and simultaneously acts as it's own Interactive Design and Front-End development project.
The UI is built using Bootstrap v4.0, HTML, CSS, and a sprinkle of custom JavaScript. While the UI design is very subtle and simplistic, composed with a basic web application structure, the UI is built to be adaptive to the device viewport and browser. It works flawlessly on any device with a modern browser, while retaining a clean and usable design. It is a single-page application, which demonstrates my diverse skill set as a programmer.
focusEGG
focusEGG is a product we worked with for a User-centered Product Development Project course for Aalto University. It is a modern pomodoro timer, which aims to aid students experiencing difficulties with focus and short attention span.
Due to information flood caused by digitalization and social media, these symptoms are experienced by a significant portion of university students. focusEGG tackles these issues by providing a modern portable concentration timer, which integrates directly with your smartphone and is very accessible. The product consists of the timer itself and a mobile application, which communicate via Bluetooth.
The product development was done with two User-Centered Design cycles, consisting of user-research, design and prototyping, and usability testing with real users. The prototype is built using an Arduino Nano microcontroller, programmed with C++.
My role in this project was in User Research, User Testing, Prototype Design, and Hardware assembly.
