Behrouz Pooladrak - Passionate Software Engineer

About

A Passionate Seeker of Knowledge, A Builder of Dreams

I’m Behrouz, a Netherlands-based software engineer building since 2008. I specialise in crafting modern product experiences—shipping interfaces that serve both fast-moving scale-ups and established global teams. Marrying design instincts with engineering rigor, I help ambitious ideas become dependable, measurable outcomes.

Day to day that looks like architecting experimentation-ready front-ends, prototyping AI-augmented workflows, and mentoring squads through sustainable delivery. I keep a calm, pragmatic cadence so polish and pace stay in sync, ensuring the products we launch feel effortless for the people who rely on them every day.

Recommendations

I have had a great time working with Behrouz

“I have had a great time working with Behrouz. We have had great chats and shared a lot of knowledge. I have learned a lot while working with him. Behrouz blended in our team as if he had worked with us for years, he got acquainted with our stack in no time and delivered dry and excellent work. I would say Behrouz definitely lives up as a Senior Dev, even though he is blessed with a bright mind, he never hesitated having a call with the team to ask questions and deliver what was expected. It would be my honour to work with Behrouz in the future again. An amazing person to have as a colleague who I consider a friend for sure. Thank you Behrouz for being with us.”

Behrooz is a person who is capable of turning an overwhelming project into a pleasing situation

“Behrooz is a person who is capable of turning an overwhelming complicated project into a manageable pleasing situation. We worked together in a team for two years and his professionalism and healthy perfectionism always motivated everybody to do their own part better. He raises the motivation of the whole team with his energetic and adventurous approach to solving problems. He possesses a powerful combination of expert knowledge and innate creativity. Last but not least, his artistic taste is worthy to be praised. I enjoyed working with Behrooz and highly recommend him as a professional designer and developer whose work in the team makes other team members strive for better results.”

Behrouz was the front-end team lead for a key enterprise project

“Behrouz was the front-end team lead for a key enterprise project and I’ve been really lucky to be a member of his team for a year. The amount of effort Behrouz puts into delivering impactful, meaningful work while tutoring/managing a team is truly awesome. He is always available to support the people around him and is a supportive person. What I love about him is that he exactly knows what he wants to do due to his expertise and extensive experiences. He is truly creative and he's the one who brings a real energy to the room. I remember when encountering problems or tight deadlines, Behrouz's always been a calm, analytical, and clear-minded leader who strives for the best quality work even under intense pressure.”

I had the pleasure of working with Mr. Pooladrak

“I had the pleasure of working with Mr. Pooladrak for six months at the PayamPardaz Company, collaborating on web design and development of a product. I've seen him not only excel at the core elements of his job -- like user interface design and user experience -- but also learn other tasks that extend well beyond the scope of his role, like graphic design for advertisement of the company’s products. No matter how tense a working day, he made sure everyone left the office with a smile. I have only optimistic predictions for his career trajectory.”
