Algo Developer / Financial Engineer

Berlin, Lviv · $2500 · 7 years of experience · Advanced/Fluent

In my first apprenticeship as a graduate economist and mathematician I had the opportunity to perform activities such as analysis of complex systems and solution‐oriented modelling of processes in a company. During my second apprenticeship as graduate business administrator, I dealt with the stock exchange software Meta Stock and developed algorithms to check the model results. Furthermore I developed sophisticated scripts to support the daily reporting to the management. In my position as software developer in Investment Banking IT I had the opportunity to tackle and implement complex customer requirements for securities trading. In addition, as an Algo‐Developer, I gained valuable experience in the development and support of algorithms for automated trading on European and international stock exchanges. My high mathematical understanding and knowledge of the capital markets provided a very good basis for this. In parallel, I took over the supervision and responsibility for the students and interns working in Investment Banking IT who were involved in sub‐projects.

I want to be part of a development team where the development processes are formed from the technical task to the final inspection. Clearly defined goals and tasks. It would be interesting to learn something new. I am open to learning and willing to learn another programming language. That's why I'm looking for a company where I can really learn, develop, introduce new technologies, gain experience and be successful together.
