I'm a Software Consultant with 12+ years of experience based in Berlin, Germany. I work with early stage startups helping them with delivering software faster through setting up the infrastructure, defining architecture, improving processes or implementing final software.
I believe that following Agile principles, independent teams, Continuous Delivery and Trunk Based Development is the best way to build software products. If it is not possible to implement them from the start they should be a direction to follow.
I prefer Kanban over Scrum as it's simpler to implement and from my experience it results in much less wasted time on often not fruitful ceremonies. If Scrum works for you - great! I have no plans to change your process then.
In a product based company I tend to avoid estimation if only it's possible. Especially story point estimation. It brings very little benefit but wastes a lot of time and effort. Instead, try to make small stories and estimate based on how much stories are delivered in a period of time.
While I am a big fan of Agile, I am terrified by the amount of Dark Agile in the industry.
I specialize in developing software with Java, Spring Framework and AWS. It is a perfect combination for many web and enterprise applications. It is not always the best choice though. I choose technology based on how it fits the customer, team and the problem to solve. Often it's Java/Kotlin with Spring but there are cases where other languages and frameworks bring more benefits.
On the frontend side of projects my default choice is ReactJS (although this page is built with VueJS, Gridsome and Tailwind CSS).
I like sharing my thoughts and knowledge. I find video tutorials very handy way of acquiring knowledge and last year I decided to set up a YouTube channel - Spring Academy with Spring tutorials and news from the ecosystem.
Speaking at events is another way to share knowledge I enjoy. I gave couple of talks in past years mainly about Spring on local meetups, then my personal life got busy for couple of years (I'm a father!). I am slowly getting back on track.
Time to time I contribute to open source projects - mainly from Spring umbrella. I was one of the first external contributors to Spring Data MongoDB project by adding JSR-303 validation capabilities and added also couple of small improvements to Spring Boot.
Have I already mentioned I like sharing knowledge? I enjoy teaching and really like to see people growing. In 2018 I joined Redi School and teach Java to refugees helping them to get their foot into Berlin job market. I am very proud to say that four of my students in 2019 started their career in software development.
I have no strong opinion if as an industry we benefit from certifications or not. I find the path to getting a certificate more attractive than a certificate itself.
I passed following certifications:
- AWS Certified Solutions Architect Associate
- Sun Certificate Java Programmer (SCJP 5.0)
- Professional Scrum Master (PSM I)
- MongoDB for Java Developers
I don't use other social medias often as I don't find they bring much value to my life. I am on Facebook because that's where most of my friends are reachable online, but other than that I don't use it much.
