Robin Walter Scherler
Last position:
Developer at agentic-engineer.online
agentic-engineer.online is my publicly testable live demo and at the same time the platform where I show my work. Originally created as a recruitment trial task, I have since continued to run it as my own demo, learning, and product project — on a Hetzner VPS behind a Cloudflare tunnel, through a multi-stage AI-orchestrated deploy pipeline with snapshot rollback. If a deploy step breaks, the system falls back to the last clean snapshot, the script is adjusted, the test repeated — empirical, test-driven, without hand tuning.
- Technically behind it: Python and FastAPI, an OpenRouter model cascade, SQLite persistence, and Cloudflare edge tuning.
- I am the developer and the strictest customer of my own AI work in one person — what started as a prototype has become a tool I use every day and against which I test my own products.

About the technology
MariaDB at a glance
MariaDB is a relational database used for transactional systems, reporting, and applications that need dependable SQL storage. It is a common choice for web back ends, internal tools, and data-driven products that need familiar MySQL-style behavior with open-source flexibility.
Common work
- Schema design and migrations
- Query tuning and indexing
- Replication and failover setup
- Backup, restore, and recovery planning
- Support for application releases and database changes
Tooling and ecosystem
Strong specialists work with MariaDB Server, client tools, and the surrounding SQL stack. They often know InnoDB, Galera Cluster, Linux, monitoring tools, and how MariaDB fits into PHP, Java, Python, and container-based environments.
When companies bring in help
Teams usually look for freelance expertise when a database slows down, data growth exposes weak design, or a migration needs careful planning. In Germany, companies also bring in specialists for hybrid setups where local teams want clear documentation, remote support, and smooth coordination with in-house staff.
What strong specialists do
A strong MariaDB professional reads execution plans, spots locking issues, and keeps replication healthy. They document changes clearly, test recovery steps, and think about availability, security, and maintenance from the start.
Related decisions
MariaDB is often compared with MySQL and Percona Server, especially when teams want compatibility and predictable operations. The right specialist can explain trade-offs around storage engines, clustering, version differences, and how to move safely from one setup to another.
Frequently asked questions
Not sure where to start with MariaDB? These answers cover the essentials.
MariaDB is used for transactional applications, customer portals, internal business tools, reporting, and many web back ends. It fits projects that need structured data, SQL queries, and stable read-write performance.
MariaDB shares a lot of MySQL history and syntax, so many teams evaluate them together. The differences matter in version behavior, feature set, and ecosystem choices, which is why a specialist should check compatibility before a migration.
Bring in a MariaDB specialist when queries slow down, replication becomes unstable, or a migration must be done without surprises. They are also useful when the current schema needs cleanup, better indexing, or safer backup and restore procedures.
A strong MariaDB professional usually knows SQL deeply and understands Linux, backups, monitoring, and application-level data access. Familiarity with schema design, performance tuning, and clustering tools such as Galera is often important too.
Yes, MariaDB work is often a good fit for remote collaboration because most tasks can be planned, reviewed, and tested through documentation and staging systems. In Germany, some projects still need on-site time for incident work, handover sessions, or coordination with local operations teams.
A MariaDB project can sometimes start with a general SQL specialist, but production databases usually need someone who has handled backups, failover, and performance issues before. The more critical the system, the more important practical production experience becomes.
Look for someone who can explain their changes clearly, show how they test them, and describe how they keep data safe during upgrades or recovery. A good MariaDB expert talks about indexes, plans, locking, replication, and rollback steps in concrete terms.
MariaDB can be a solid target for migration when the current application expects familiar SQL behavior and the team wants open-source database operations. A good specialist checks stored routines, character sets, replication design, and application queries before moving anything.
The average hourly rate of freelancers in Germany who have used MariaDB in their recent projects is 96 €, which corresponds to a daily rate of about 769 € based on an 8-hour working day.
Of the freelancers in Germany who have used MariaDB in their recent projects, 78% hold at least a Bachelor's degree, 43% hold at least a Master's degree, and 12% hold a doctorate.
