Mobile App Developers
in Vienna

I'm an experienced full-stack developer who has been working as a freelancer for over 10 years now. Right now I'm focused a lot on developing with Elixir, but most of my time I have spent working on projects with PHP. I love creating software that's usable, testable and maintainable. Front-end wise my current framework of choice is VueJS. My projects range from short term projects for smaller customers to bigger and longer projects with bigger companies. My working times are rather flexible, so I don't have a problem working something out that fits me and my clients. I look forward to working with you!

I’m a technology enthusiast who loves building innovative tech. I've been working on a lot of different projects for different clients both enterprise and small businesses. Some of the companies I've worked for include AXA Assistance, Zurich Insurance Group, Vienna Insurance Group, Siemens AG, T-Mobile Austria, Diners Club Bank AG, and more. I've been tutoring for and advocating robust backend API development from design to deploy with TDD and SOLID principles and with particular attention to security making sure to test and cover against OWASP-documented vulnerabilities. I've been involved with configuring and creating an Elastic cloud installation, structuring logs from different sources, and creating different dashboards on Kibana. I've also integrated APM and ML on Elastic cloud to monitor and alert for unusual system reports. Along with my specialties, there is also mobile development. I have a lot of experience building mobile applications with cross-platform frameworks such as React-Native or natively Objective-C/Swift and Java. Recently I have built with Gustaffo in Vienna, Austria, a digitalized guest journey for a different number of Hotels. Our solution is a mobile application integrated with our own web services designed on a microservices architecture. The solution works tightly with our Property Management Systems and lets users perform from their mobile device the check-in, signing of the registration card through digital signature, room service requests, web checkout, and payment. Other recent implementations include a mobile application for Diners Club Austria. And more. I've built different high load web applications that handle to this day from 6M - 10M monthly hits.
