Nelkinda Team: Christian Hujer
Christian HujerSoftware Craft Coach
Founder / CEO / CTO
Christian Hujer has 35+ years of experience in software development. He founded Nelkinda in 2014/2015 to shape the software development process to advance further, exploring the bleeding edge of Software Craft and pushing boundaries forward.
During his career he has trained and coached teams and individuals from many companies such as E-Plus Mobilfunk GmbH & Co. KG, GfK AG, Giesecke & Devrient GmbH, KKH Kaufmännische Krankenkasse, KPTronix Technologies, Nokia Austria GmbH, NorCom AG, Siemens AG, Software AG, Sun Microsystems Inc., Volkswagen AG, BNP Paribas, and many more.
He is polyglot in languages (Prolog to Go, Assembler to Java), frameworks, and development environments (smart card to server). Here's examples of the technology stacks in his latest projects:
- full stack development with HTML5, JavaScript, CSS3, REST, Spring, Groovy, Spock, migration from Heroku to AWS EC2.
- Migration of a monolithic Ruby on Rails application to a microservices architecture, with microservices written in Java / Spring.
- Point of Sales application on Android with an Arduino device; back-end server in Python.
- Live migration of 190M records from Amazon DynamoDB and S3 to MongoDB in a project based on Java and Spring.
- full stack development with React JS, React Native, Golang, Java, MongoDB, CosmosDB, Azure, Azure DevOps, Godog, Cucumber, Selenium, and Appium.
In his previous job he had lead and architected for multiple teams (90+ developers and testers) working on a shared code base of 850k sloc embedded production code (Assembler, C, Java) and 9M sloc test code (C, C++, Java) across three international sites in Europe and India for multiple years through a journey from waterfall to Agile, ClearCase to Git, 30 minutes build to 2 minutes builds, 14 hours to 2 hours test, introducing unit tests, lots of process optimization, TDD and Scrum - he knows how to handle big stuff.
He is a strong advocate of XP & Clean Code practices on his teams & elsewhere at work.
