It’s simpler than you might think. My name is Payam, and I’m a developer based on the famous Wallstraße (literally ‘Wall Street’) in Berlin. I founded ‘Wallstr Dev’ from my home office here, blending the precision and focus the name implies with the direct, personal commitment you can only get from working one-on-one with a founder.
I partner directly with clients to build, because I believe technology should be a strategic asset, not a perpetual source of frustration. Too many companies are caught in the reactive cycle of fixing technical debt and managing systems designed without foresight.
My mission is to end that cycle. I provide the senior-level architectural strategy required to move you beyond constant firefighting and build robust, scalable, and secure systems that drive genuine business growth. I translate complex, high-stakes technical challenges into clear, confident, and actionable blueprints.
I recommend the best stack for your budget and goals, not just the tech I like.
Founder-Led Development. No middle-managers, no outsourcing. Just you and me.
