Hi, I'm Sascha

Programmer of your choice

I'm a Full Stack Developer based in Austria, focused on building scalable applications with a clean architectural foundation. My daily toolkit centers on C# and .NET for robust backends, paired with TypeScript to create seamless frontend experiences. I enjoy bridging the gap between complex logic and user-centric design to deliver high-quality software from the ground up.

Actively participated in the Creativity Award and the Startup Camp to foster an innovative mindset.

2015 - 2020

Matura & IT Diploma

IT HAK Imst

Completed 5-year technical education with the Matura exams. Gained a strong foundation in Software Engineering (Java, PHP, JavaScript) and frameworks like Spring and Laravel, alongside Robotics and IT Security. The final diploma project was 'Hadu,' a full-stack social media application engineered with React Native and MongoDB. The curriculum also included significant training in business administration and economics.

C# & .NET

Architecting robust backend services with C# and the .NET ecosystem, from modular APIs to microservice-oriented systems. Experience with event-driven patterns, background workers, scheduled jobs with Quartz, and maintainable service boundaries for business-critical applications.

TypeScript

Extensive experience with strict typing to build scalable, maintainable codebases. Utilizing advanced utility types and interfaces to reduce runtime errors across full-stack projects.

OpenAPI

Creating solid API contracts that are easy to consume, document, and evolve. Using OpenAPI specifications for contract-first workflows, client/server generation, and reliable implementation across C# backends and TypeScript frontends.

Domain Driven Design (DDD)

Structuring complex software systems by aligning the code architecture directly with evolving business logic. Breaking down monoliths into bounded contexts for better modularity.

Next.js & Svelte

Building high-performance frontend applications with modern meta-frameworks, including SSR, SSG, routing, and optimized rendering. Working with Next.js and Svelte/SvelteKit to create fast, maintainable, user-focused interfaces.

DevOps & CI/CD

Managing collaborative workflows with GitHub and Azure DevOps. Designing and maintaining GitHub Actions, Azure pipelines, automated test/build flows, and deployment processes that keep delivery predictable.

Docker & Kubernetes

Containerizing applications with Docker and Docker Compose for local development and deployment. Working with Kubernetes concepts, kubectl workflows, Helm charts, service configuration, and reproducible runtime environments.

Database Management

Designing efficient relational schemas, writing optimized SQL queries, and maintaining data integrity for data-intensive applications. Working with NoSQL databases where flexible document models and scalable access patterns are a better fit.

Requirements Engineering

Translating business needs into clear, testable software requirements. Facilitating stakeholder alignment, refining user stories and acceptance criteria, and keeping implementation decisions grounded in the actual problem domain.
