About Me

I bring along many years of professional experience in cloud solution architectures, DevOps and end-to-end software development.

 

As a self-employed Solutions Architect and Full Stack Developer from North Germany I specialized myself in designing and developing effective, innovative and elegant cloud and software solutions for day-to-day contexts as well as challenging, enterprise-scale environments. My strong passion to create something new and to understand complex contexts as a whole is coupled with high self-learning competence and sensible decision making. This fundamental skill set allows me to deliver solutions that do not only fulfil the task at hand, but also follow industry standards with scalability, cost effectiveness and future reliability in mind.

 

At BidFlow Technologies, where I am the Managing Director to this day, we are trading the financial markets in different manual and fully automated ways. Developing its sophisticated tech stack over the course of the years allowed me to obtain versatile and in-depth know-how in a variety of critical areas (highly scalable cloud infrastructure, low-latency event-driven systems, Big Data management, DevOps, distributed systems, backend/frontend development, data science and more).

 

I am also collaborating with the IT industry via external IT projects, also with enterprise-scale clients, to further hone my skills and to deliver the best possible value where it actually matters.

 

Through BidFlow Technologies, I am offering bespoke IT consultation, cloud solution architecture and development services.

16.11.2023 How to build a scalable streaming data pipeline for financial big data

High-quality historical financial data offers a direct competitive advantage in the systematic trading business, but its big data qualities make it both costly to manage and store as well as very expensive to buy from external sources. To mitigate a part of these expenses, a custom, self-managed data lake can be built by recording and storing real-time financial data through a scalable streaming data pipeline.
