Literature and History of Arts

Philosophy and Economics

I started out as an intern in the marketing & communications department of the DACH region. While working there I was unsatisfied with the way press clippings were stored, analyzed and retrieved. I offered to build a better tool. This led to an extension of my internship and a freelance job later on when Booz Allen Hamilton spun off its commercial sector consulting groups. 

Marketing Communications Intern

I helped migrating a tool that I built for the company during an internship in 2007 after Booz Allen Hamilton spun off its commercial sector consulting groups. 

Freelance Software Engineer

I co-founded Tech Team Berlin with a good friend to create great software for great people. Our clients included companies like Homeday and Kurabu. I managed projects end-to-end, overseeing business development, sales, and marketing.

Our tech stack included Elixir, JavaScript, Python, and Ruby.

Co-Founder & Partner

Freelance Software Developer and Consultant

As Head of Software Development at Factory Berlin, I built the software development team from the ground up and led the creation of an internal social network for our members. I collaborated with multiple teams, integrated third-party services, and mentored students from CODE University, which was particularly rewarding.

This role allowed me to enhance my technical and leadership skills while building a strong network within Berlin's startup ecosystem.

Tech Stack: Elixir, React, Angular (2+), Docker, PostgreSQL, Elasticsearch.

Head Of Software Development

Software Engineer

Co-founder of codeshift where we connected software engineers from East Africa with the tech industry in Europe.

I managed projects end-to-end, from sales and initial estimates with clients to leading the engineering team and acting as a bridge between all parties. It was one of the most rewarding roles because I got to work with a diverse group of people and engage with the startup scene in Rwanda.

Codeshift specialized in building complex web and mobile apps, collaborating with startups, SMEs, and agencies like Melitta, GoVolunteer, BCG, 3PC, and Circulor.

A key part of our mission was to have a positive social and economic impact. We offered above-average salaries and mentored junior developers to help them reach the highest international coding standards.

- Writing microservices to automatically post listings on external sites.
- Build modular flows to collect leads on different sites.
