Our team

Marianne Damstra

After approximately 10 years of experience at ACE and being responsible for SuperTest, the opportunity arose to acquire SuperTest and start my own company. This is a great adventure that I enjoy every day since I am glad to learn new things and meet new people. Understanding new markets and filling gaps by improving our products as a TEAM is what I stand for.

Besides running this company as one of its co-founders, I like to play competitive basketball and being active with my family in my spare time.

Marcel Beemster

I love the C programming language, right from the first day I picked up K&R’s book, because it provides a direct connection with the machine at high performance. That book was destroyed by a Chinese professor with a fondness for Prolog who sat on it for reference while writing a device driver. C is that flexible. It did not stop me. C has its issues, but so has <insert your favorite language here>. My long term goal is to make sure our C programs and implementations are of the highest quality possible.

José Luis March Cabrelles
Software Quality Engineer

I received a Computer Engineering Degree, and a Master’s on Networks and Operating Systems, at the Technical University of Valencia (UPV) in Spain. Afterward, I studied a PhD focused on Processor Microarchitecture, devising different techniques to dynamically reduce Power Consumption in Multicore Embedded Systems while they are executing tasks with Real-Time constraints. Finally, after a career break in Västerås (Sweden), I joined Solid Sands as Software Quality Engineer in the summer of 2016.

Monica Visser
Head of Marketing and Communication

After my study in Marketing and Communications, I joined the team of Solid Sands in 2017. My interest lies in creating unique ideas and new content, which is why I am curious about the unknown and like to take on a challenge. This is exactly what I found in Solid Sands, working on the marketing department for such technical products, SuperTest & SuperGuard, makes work quite interesting.

I am motivated, enthusiastic and keep myself sharp by pushing myself and setting goals. When I am not in the office, I enjoy traveling and exploring different cultures.

Remi van Veen
Qualification Lead Engineer

My interest in compilers was fueled by the compiler construction course at university, which is my favorite course of all time. For my Master’s thesis in Software Engineering, I joined Solid Sands to research the testing of compiler optimizations in 2018. After graduating, I productized my research into the SuperTest compiler optimization test suite. Today my main focus is on leading compiler and library qualification projects following various functional safety standards. I really enjoy advising our customers about the safe use of their compilers and libraries.

In my spare time, I like traveling, cycling, going to concerts and watching lots of football.

Vladislav Yaglamunov
Software Engineer

I was introduced to C++ in high school, I was participating in lots of algorithmic programming contests and C++ simply had the fastest execution times, so it was the obvious choice for many contestants. I was not aware of all the depth behind it until I had a course on it in university, where I was completely shocked and amazed by it. There, I also got interested in logic and formal methods, and so I moved to the Netherlands to study it and that is how I joined Solid Sands for my Master's thesis in formal verification of C library. In my free time, I enjoy movies and online games, occasionally, I like snowboarding and table tennis.

Ivaylo Ivanov
Software Engineer

Led by love for problem solving sparked by high school competitive mathematics and a passion for technology dating back to the time I first touched a keyboard, I moved to the Netherlands to expand my knowledge and skills in an academic environment. I joined Solid Sands for an internship as a part of my study and I really enjoy tackling the challenges I face on the job. Endless curiosity and willingness to learn are the things that keep me going. When I'm not in the office you can find me either on the ski slopes or at the trampoline park.

Gabrielle Espejo
Worldwide Sales Representative

Originally from the Venezuelan Amazon, I came to Europe 14 years ago. Embracing my passion for the technology industry, I embarked on an exciting chapter with Solid Sands in 2022. Starting as an office assistant, Solid Sands allowed me to grow within the company. I now proudly serve as a worldwide sales representative, constantly expanding my expertise in the dynamic realm of IT.

I consider myself a curious person by nature and I am always willing to learn new skills, that is why I am currently combining learning Dutch with programming studies, an area that generates great interest for me. In my free time when I am not in the office, I may be cooking, adjusting my camera lens to take photos, taking care of my plants, or at the airport embarking on a new adventure.

Elisa Costantino
Operations Manager

I have always had a strong passion and curiosity to learn about different cultures and, as a result, have spent several years traveling as a way to expand my knowledge and continuously grow as an individual. I’m a people person, I’m empathetic and have strong listening skills.
I’m super rational and I can pride myself on my problem solving attitude. Challenging the “what if” in any given situation, gives me the opportunity to become the go-to person in times of need. I’m always excited to learn new things, I have random curiosities about unrelated topics.

In my spare time, when I’m not in the office, I usually cuddle my cats or teach a new trick to Tuna, my dog.

Ahmed Abdulbaki Ibrahim
Software Engineer

During my quest of becoming a Computer Engineer, I frequently became acquainted with and loved studying C++, compiler design, and software quality metrics. After I completed my BSc back in Egypt, I decided to specialize in Software Engineering and moved to Amsterdam to obtain my MSc from the UvA. I interned at Solid Sands to complete my thesis research regarding C++ code coverage tools, and truly loved the experience! Following the MSc’s completion, rejoining the office was a no-brainer.

I'm always excited to meet new people, try new experiences (except eating vegetables) and learn more and more every day in the neverending domain of software! When not on the office desk, I am most probably either in the gym or enjoying junk food, no in-between.

Stefanos Teberikoglou
Worldwide Sales Representative

In 2019, I decided to move from Athens, as Amsterdam has always been one of my favourite destinations.

With strong experience in sales, communication, and customer service, I decided to join the Solid Sands team to elevate my experiences. I could characterize myself as a team player, but sometimes I can be very stubborn.

In my spare time, you will find me practicing martial arts in a nearby gym, enjoying a local beer with a bitterballen, and listening to techno music.

Max Blankestijn
Software Engineer

At a certain point in middle school, maths clicked for me. When looking for a way to apply it afterwards, I was immediately at home at my study of Computer Science in Leiden. With C++ the language of choice, I dove into theoretical informatics, computer systems, algorithms and software verification. After finishing and publishing my Master's thesis, Solid Sands turned out to be a perfect match.

Besides computer sciences, I also like to dive deeply into history, mythology and works of fantasy. Simply because it's interesting, or to adapt it into personal writings or tabletop RPGs. Otherwise, I like going on a nice walk to think and climbing.


Nefeli Tavoulari
Intern Software Engineering

Since I started my IT journey, I have been fascinated by the challenges of low-level programming and compilers. This passion first emerged during my bachelor's studies at the University of Athens. Building on this, I pursued a Master's in Software Engineering at the University of Amsterdam. I joined Solid Sands as an intern, trying to establish a qualification method for non-standardized languages, using Rust as a primary example. Beyond coding, I find joy in photography, hiking, reading books, and listening to music.
