As Elektrohub's sole engineer, I owned development of a business-critical e-commerce and operations platform spanning order, catalog, customer, and internal workflow systems.
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.
Full-Stack Cruise
Mar 2024 - Feb 2026
Next Build
Product Engineering
I am building ShiftIQ as an intelligent shift management platform that combines a recruiter- and operator-friendly product experience with deeper scheduling logic in the backend.
Product Excursion
Product Development
I built Sparky to create a better connected-car experience, adding Siri support, widgets, Live Activities, richer drive data, and more flexible climate scheduling.
Hardware Detour
Software & Hardware Engineering
Alongside the mobile companion app, I started improving the in-car experience itself through a custom ambient lighting system with smart integration into the vehicle.
Systems Leg
Aug 2021 - Jan 2024
I took on real software engineering responsibility early and contributed well beyond a typical apprenticeship scope, working on production desktop software used by customers.
Credential Stamp
Professional Certificate
Credential covering full-stack development, cloud foundations, containers, deployment, and modern application architecture.
Reverse-Engineering Stop
I adapted an existing mod to revive a specific older Fortnite build and extended it with live event logging to surface interesting in-game changes.
First Departure
Mar 2019
Siemens Gamesa Renewable Energy, S.A.U
During my internship, I worked close to hardware and real-time data handling, which gave me an early foundation in reliability-focused software development.

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.
