Hi,
I am Joschua Haß

Full-stack engineer focused on operations and product systems. I build reliable applications end to end across React, Next.js, NestJS, TypeScript, and .NET, with hands-on ownership of architecture, integrations, performance, and production delivery.

About Me

I started building software seriously as a teenager after one of my favorite collaboration tools for virtual trucking companies in Euro Truck Simulator 2 shut down. Instead of accepting that gap, I built a replacement for the community and got pulled deeper into product thinking, user needs, and shipping software people actually rely on.

Since then, I have grown into an engineer who is comfortable owning the full stack: frontend experience, backend services, integrations, performance bottlenecks, deployment pipelines, and day-to-day production responsibility. My recent work has centered on e-commerce, internal operations software, and modernizing legacy systems without interrupting business-critical workflows.

Outside of work, I still enjoy building smaller software experiments across web, backend, mobile, and desktop when a problem feels worth solving. I am especially interested in products that combine strong usability with deeper technical complexity behind the scenes.

When I'm not at the computer, I'm usually traveling, spending time with friends, doing photography, or flying in Microsoft Flight Simulator. Aviation and travel are a big part of what keeps me curious and energized outside of engineering.

Career Timeline

From embedded systems to desktop software to full-stack product ownership, this is the route so far, including the side builds and credentials that shaped it.

Interests & Passions

日本 (Japan)

I keep telling myself each Japan trip will be the last one for a while, and then I somehow book another. I went four times last year, changed flights mid-trip once, and now study Japanese daily with a vocabulary that is still disproportionately useful in restaurants. The mix of culture, food, and scenery has fully won me over, and my friends can usually tell when I am about to bring Japan into the conversation again.

I have a deep passion for flying and exploring the world. Through my travels, I've had the opportunity to experience different cultures, meet amazing people, and create unforgettable memories. Here's a summary of my flight journeys:
