About

I'm a Full-Stack Software Developer and Entrepreneur from Germany interested in designing and building innovative software systems, MVPs, prototypes, and proof of concepts. After co-founding the Startup Talentwunder, freelancing as a Software Developer, and working almost 10 years in applied research at SAP and Fraunhofer IESE, I'm open to help other entrpreneurs and starting new enterprises.

Offerings

Software Engineer (Freelance)

As a freelancing Software Engineer, I support software development projects in Frontent, Backend or DevOps activities.

My expertise focusses on the topics Web, Mobile, Cloud, DevOps, and Search — mainly using the technologies React (JavaScript / Typescript), Next.js, Gatsby.js, Groovy (Java), Grails, AWS, MongoDB and ElasticSearch. Currently, I'm also very interested in the technologies React Native, Micronaut, Kubernetes & Docker, AWS Lambda and Amazon Alexa Skills and I'm working on several side projects with them.

I enjoy to maximize the automation of software systems & development infrastuctures as well as the rapid but systematic development of software.

Startup Advisor

As a Startup Advisor, I support Startups, Scaleups, Grownups, Entrepreneurs and Freelancers in the setup, operations, and automation of their venture. Having co-founded Talentwunder (exited 2020) I accumulated knowledge on building, managing, and scaling Big Data Startups.

This knowledge enables me to assist in hiring, building and managing agile engineering teams, mentoring CTOs, monitoring continuous development and deployment activities, crafting and prioritizing successful product roadmaps, as well as designing and automating scalable tech architectures. On top, I help startups identify, validate and execute sustainable business models with technology.

Furthermore, I support startups in preparing a tech due diligence and advise investors to make smarter decisions by providing clear fact-based and business-oriented insights.

Researcher

As a Researcher, I support Scientists, Research Groups and Startups in the setup, execution, evaluation of research endeavours as well as fundraising for research projects. My time at Fraunhofer IESE and SAP helped me learn critical success factors in planning, conducting, and analyzing empirical research in Software Engineering projects.

This experience enables me to assist Scientists and Marketers in executing empirical research by testing research and marketing hypotheses using tools such as surveys or experiments. Beside supporting empirical research I can help writing successful research project proposals for EU and German (BMBF, BMWi) research grants.

Previously, my background was rooted in the fields Empirical Software Engineering and Data Mining (applied to software-documents). In particular, I was interested in the diagnosis and refactoring of quality defects (Antipatterns, Code Smells, Design flaws, etc.), Experience-based / Pattern-based Software Engineering, Software Ontologies, Model-Driven Software Development (MDSD) as well as knowledge discovery and machine learning in code and defect repositories.

Projects

Following the lean startup and agile development ideas, I'm involved in several projects that have or might become full-fledged startups sometime. The main projects I'm working on or worked on are listed below.

Active Projects

techmap.io (2020-today)

Techmap.io is a tech workplace search engine to find companies using specific technologies in an area. It help individuals and recruiters to find companies that are using technologies (e.g., Rails, PHP, Java, etc.) one likes or has the right experts to offer as temporary workers.

PayDevs.com (2022-today)

PayDevs is an idea in progress to improve the Monetization of OSS.

Exited Projects

Talentwunder is a platform to support active sourcing activities by individuals or teams in order to help companies identify and hire the best talents worldwide. As the Co-Founder and former CTO of Talentwunder I build the initial System, grew the Development Team to 7 people, and was responsible for driving the company’s technology vision.

Dormant Projects

CasuMe (Casual Mentor) is a hub to search for people with specific skills you want to learn. Whether you want to learn how to cook ramen, how to tune your car or learn a new programming language.

LevelCentral.com (2012-2013)

LevelCentral was a platform for acquiring levels in skills and professions in order to build a skill based profile, to compete with others for the top position, and to find experts in your social network or location. Organisations in the Education & Training sector will be enabled to award levels, certifications, and badges to their students.

CrowdYell.com (2011-2012)

CrowdYell was a location based chat system for you and your friends, your family, your colleagues, concerts, conferences, etc. that will help you exchanging information with like-minded people around you, without polluting other chat solutions such as Twitter or Facebook.

Closed Projects

Startoholics was a social network for founders, startups, investors, designers, and programmers focused on helping startups in early phases. Startoholics mission is to motivate, connect, and enable people to realize their ideas and start new companies.

Kickstart Plugin (2011-2014)

was a plugin for the Grails 2 Framework in order to start a web project with a good looking frontend. It is intended to be used in rapid application scenarios such as a Startup Weekend or a prototyping session with a customer.

InnoSparks (2012)

InnoSparks was a SAAS platform for business angels, venture capital companies, and incubators to support the management, evaluation, and remote pitching of startups. The first step is the ranking of startups in diverse sectors and locations based on the comunity and other metrics.

The Grails App Configurator (2011)

was aimed at easily and quickly configuring an application via an visual interface and enable the user to specify the plugins, database, UI framework, and other technologies he wants to have in an application. The result would be a setup script, or better, directly deployed to a PaaS/Cloud (e.g., Cloudfoundry, Heroku, etc.).

Musicclip.tv (2011)

was a personal music video channel, which extracts your Facebook music likes and finds similar artists that are used to construct a playlist with music you like. The playlist is then used to feed a Youtube player in order to play personalized music videos to you. As a Startup Live RhineValley 2011 project we build it in 54 hours!

work'n'play camps (2011)

was a Startup Weekend (Stuttgart 2011) project to build a community for mobile entrepreneurs, developer, and designer who want to work in nice and inspirating environemts. Just imagine you could work from a Villa in Mallorca, a French Castle, a ski lodge in the Alps, or a metropole like Prag - together with other motivated professionals!

was a location based lottery system for brands where players have to solve different tasks (e.g., scan a QRCode, answer a question, share a link, etc.) to acquire tickets for a lottery to win some prices (e.g., product samples, money, cars, etc.). The goal is to make the interaction of people with brands more interesting and challenging.

xomni (2009-2013)

was a social network platform with the goal to help users in creating and managing a presentation of themself to foster the communication among all participants. The platform is based on semantic technologies in order to help to describe relations between people, things, and organizations using freely definable relations.
