- Working with Sina was not only a breath of fresh air, but an experience I’ve never had before working alongside an engineer.
His fast response time and attention to detail made the song better than I could have ever imagined. His keen ear for understanding what the customer wants along with incorporating his own talent, resulted in a master quality end product.
Carlos Diaz - wishyouwere dead
- I have worked with professionals before but never with someone who is as passionate about music and puts in so much effort as you. A great guy and a great professional

- Sina was able to dial in exactly what I needed for a new project. He knew the genre and created some sick tracks that was up with the current trends. The track was so polished (even down to the drums) that no further adjustments were necessary
Marko Svudade - MORIR / OceanWITHERER
- I contacted Sina looking for his signature sound characterised by aggressively charged guitars and basses and devastating drums that explore the limits of modern metal productions. But I found much more than that. His ability to transform my lifeless and robotic sounding drums into sections full of energy was undeniable. I also found someone with a very good vision to get the best out of the sections in the songs.
I wish I had started working with Sina much earlier in the composition process so I could have taken full advantage of those qualities. And that's something I definitely plan to change for future material to avoid falling into incoherent structures and wasting good ideas."

- Sina is a professional who not only brings incredible ideas to the table but is also open to interpretation and collaboration, always striving to bring out the best versions of the songs. Whether it’s a fully finished track or just a rough idea, working with Sina was not only incredibly enjoyable but also deeply inspiring due to the speed and efficiency with which we worked on the tracks.
Rasmus Karlsson - In Faith We Fear
- Working with Sina is always a pleasure. He made my vision come to life and I totally recommend him.
His burgers are also sick!
