A Bit About Me
Hi, I'm Juhani, an ISTQB® certified Software Tester and English-to-Finnish translator. I'm a native Finnish speaker, and I currently reside in sunny Barcelona, Spain. I've always had a knack for languages and technology.
​
I grew up in Finland, and over the years I've dedicated myself to honing my translation skills, specializing in translating and refining web content from English to Finnish. This includes both human-written and AI-generated content. People often turn to me for proofreading websites and apps in Finnish, ensuring that the language feels natural and resonates perfectly with the local audience.
​
In addition to translation, I have a passion for streamlining work processes. I hold a certification as a Lean Six Sigma Green Belt, which means I excel at finding innovative ways to optimize workflows and improve efficiency.
​
My experience in software testing covers a wide range of projects, including mobile apps, websites, and desktop software. I've worked on diverse tech projects, ensuring that software is in optimal condition for deployment and user-facing content is accurate and polished.
​
What sets me apart is my ability to communicate fluently in both English and Spanish, guaranteeing effective and transparent communication throughout our collaboration.
​
However, I'm not all work and no play. When I'm not in front of a screen, I indulge in my passion for mountain biking and hiking in the picturesque mountains of Barcelona.
​
By having me on your team, you gain access to a skilled translator and software tester who excels at refining AI-assisted workflows, improving processes, and ensuring linguistic quality.
I serve as your bridge between languages and technology, enhancing the efficiency and overall quality of your projects.
