A React-based telematics solution to manage vast fleets of vehicles. I worked as a front-end developer, and closely with the back-end developer, UI/UX team, product owner, and project manager to create an amazing product.

This is one of the biggest travel portals in German-speaking countries. I maintained their legacy system. It ran on PHP and a custom jQuery framework. I also developed their next-generation platform built with React in the front end and lean GoLang/Node.js microservices.

This is the biggest B2B marketplace in Europe. I was working as a front-end developer and as back-end support to create a next-generation platform to replace their legacy monolith solution. We deployed to AWS with Terraform.

Together with my team, we created a marketing analysis tool with an AI-enabled back end and 3D visualization of data on the front end using AngularJS and D3.js. My job was to estimate the project, design the graphical interface, implement the AI on the back end, and develop the visualization and project/client management interfaces. I also created the video presentation using Adobe After Effects.

Together with a small team, we created a behavioral analysis tool that helps one measure and visualize a person's behavior patterns and portrays connections, dependencies, and influences in a multi-dimensional space. My job was to estimate the project, plan the implementation, create the back-office with client management, create automatic invoicing and technology sub-licensing to certified partners, and create a user control panel and a flexible questionnaire system on the front end.

I developed a highly-scalable, high-performance white-label online, and PoS betting platform. My primary responsibility was to redesign the old monolith into a lean microservice architecture and develop the user area (profile) views.

Designed and patented a distributed, accessible, messaging network to ensure consistency and consensus in unstable and highly malicious environments. Developed a PoC cyptocurrency ledger based on the patented consensus technology.

Worked with the Finanzcheck team to create a flexible, white-label questionnaire strip for user data collection and the posterior presentation of fitting offers. Assisted in tools and frameworks selection for the task and developed the PHP API.

Founded the biggest German-speaking social platform for professional nail designers with thousands of users. Completed the whole startup lifecycle from conceptualisation, planning, prototyping, financing, development and posterior exit. Sold the company to the biggest German nail design supplies manufacturer and retailer.

This is a large German agency offering digital transformation solutions to its clients. I worked on many different proof-of-concept projects, usually completing the entire software development cycle from estimating, consulting, planning, implementation to feedback tracking. A wide variety of technologies and requirements were utilized. We built small landing pages up to high-traffic solutions for clients like McDonald's.
