Digital Project Manager, Frontend Developer, UX Designer
This page is mainly for me to remember and keep track of things. If you're looking for more info, head over to kristofferekstrand.se instead.
What I do: I'm a project manager who builds digital solutions and experiences - mainly focused on e-commerce, but also design, development, and other digital projects. Plus music technology stuff like the Adventure Kid Waveforms.
Work I'm proud of: As a frontend developer with a very skilled team at Vinoteket (Sweden's big online wine store), I redesigned and optimized the web for technical SEO, worked with tracking, optimized for web vitals, and removed all problems in the frontend code which both made it a better user experience but also affected SEO positively. My role primarily focused on frontend development, but I also contributed to brand identity work including logo updates and various other aspects of the digital experience.
Interested in working together? I'm always up for interesting projects - whether it's e-commerce, web development, or anything music tech related. At Grand Public, I work with a creative branding agency and great developer team, so we can deliver something neat and impactful.
These are smaller projects or apps, or sometimes something entirely different. Many are web-related, but they can also involve sound or music design, technology, cooking, or a mix of everything. It's a space for just about anything.
What it is: A collection of over 4,000 single-cycle waveforms that synthesizer companies use in their products. It started as a hobby project but turned into something people actually use.
Why I made it: I was playing live with digital synths and needed them to sound more analog without eating up CPU. Traditional additive synthesis was too heavy for my laptop on stage, so I tried baking harmonics into single-cycle waveforms instead.
How it's used: These waveforms help make digital synthesizers sound richer while using minimal processing power. They work well for hardware manufacturers with limited processing and software developers who need royalty-free content.
Open source: I released everything into the public domain when UK schools started using them for education. Now they're in synthesizers and samplers from various companies.
Personal Projects & Lab Sites
Side projects where I experiment with different technologies, music stuff, and web solutions. These are mostly for fun and learning new things.
My music technology site where I work on sound design, synthesizer programming, and audio tools. This is where the Adventure Kid Waveforms live, plus other music tech experiments and Web Audio API stuff.
My electronic music project focusing on chill EDM. Think classical dance music but more laid back - like music for a holiday. I'm going for something simple and easy to listen to, obey the pattern.
My personal site and blog about building digital experiences. I write about choosing the right platforms and technology, web standards, optimization, and keeping things simple - focusing on how to build things with real impact.
A recipe site with nutrition database in early development. It's an experiment with how much you can solve in the frontend - like search and filtering - on top of a static site. Also an SEO experiment, and hopefully it'll make me cook more and better.
Two sites for my sound production work. One showcases my services - samples, synth presets, jingles, intros, and sound branding. The other is a self-service portal with downloads and sound brand guides. Not active right now but starting up again in the near future.
