Nice words by nicer people

Anne-Marie Scheidegger

Scrum master and manager - fastforward websolutions

Ingvi delivers on time and is a very reliable person. He often foresees potential technical and as well UX problems and always comes up with simpler alternatives. He has a professional and flexible manner with our clients and is simply a dream to work with.

David Aerne

Developer and founder - Elastiq

He cares a lot about HTML/CSS, semantics and scalable design patterns. His ability to recognise the right CSS approach for a design problem keeps impressing me. I hope I will have the opportunity to work with him again.

Christof Leuenberger

Technology architect - Die Mobiliar

Ingvi joined our team during the Covid-19 lockdown and despite the circumstances, quickly acquainted himself with the project and took on his role in the team. His calm manner and meticulous eye for detail as well as his expert subject knowledge played an elemental role in delivering the product on time.

Hilmar Gunnarsson

Founder and CEO - Arkio

Ingvi is a very talented frontend developer and a pleasure to work with. He is professional, focused, delivers what he promises on time and has a good eye for UX and web design.

João Figueiredo

Web Accessibility Consultant and founder - Aditus

During both our time at Ginetta, it was a pleasure to work with Ingvi. He is extremely knowledgable on good, semantic and accessible HTML/CSS and he clearly has a passion for doing things correctly. He was one of the main accessibility advocates at the company, and he is a very good teacher. Everyone should have an Ingvi on their team.

Little bit about me

I’m a developer with over 10 years of experience. I have worked both as a freelancer and in couple of agencies and have a reputation for having a keen eye for details and for delivering products on time. In early 2020 I created a company, ljomi GmbH and I work since then as a self-employed.


I’m serious about markup. The structure that lies underneath every websites. Well crafted markup can do a lot of good for any website and is essential for responsive web design, findability in search engines and for accessibility. I pay great attention to the details and I make sure that everything is in its right place. Get a copy of my resume for more details.

Free time

In my spare time I enjoy tinkering with open source projects and to teach teenagers how to develop and design for the web. When offline I do yoga, run, make music or most likely spend time and playing games with my family. I love my records and having music in a physical form is very important to me. Playing music as a dj used to be a big part of my life but has lately taken a back seat as a past time hobby.
