Martin in wenigen Worten

My name is Martin Vielsmaier. I work as an independent software developer in southern Germany & remote. My main focus of expertise and interest is in backend technologies. I speak both German and English.

I can help companies on different levels:
  • If you have a strong team with good practices I can just pitch in to get more things done.
  • If your team lacks some skills or practices (DevOps, TDD, Architecture or OOP), I can help establish those.
  • If you don't have a team and work with an agency, I can be your technical advisor to ensure you get the most out their work.

I have several years of experience in building software solutions for various problems using a wide range of technologies. I have used Ruby, Python, Scala and Java in backend systems and some flavors of languages compiling to Javascript (and JS itself of course) in UIs. In most projects UIs were made of web technologies, but I also worked with Swing and Android. On the database side, I have mainly worked with MySQL, PostgreSQL, Redis, MongoDB and Google BigQuery. I also have solid experience with both SOLR and Elastic Search.

Another part of my work spanned activities around build, testing, integration, deployment and operations of the systems I built (aka DevOps). In this area I worked with several testing frameworks, CI tools and deployment options: RSpec, Cucumber, Selenium, nosetest, pytest, Jenkins, Cirle CI, Travis CI, dedicated Linux servers /w automatic provisioning, AWS (EC2, RDS, Cloudformation, Lambda, Elastic Beanstalks, ECS, CDK, EKS), Docker and Kubernetes.

Working together with Martin at Eluminocity GmbH was great for us. He helped us setup the software components that allowed us to communicate with our street lamp sensors all over the world. Also the teaching from his side and the documentation helped us long after his freelance contract ended. I can highly recommend Martin.
