Senior Cloud-Native Java Engineer and DevOps Engineer, building services and running the platforms they live on. One engineer, both sides. Based in Germany, available across DACH and remote.
Building production-grade Java microservices with Spring Boot — designed for scale from day one. From synchronous APIs to event-driven architectures, I write services that run reliably from the first deployment. Clean code, testable, observable, ready for CI/CD pipelines.
Designing and operating platforms that run on Kubernetes — automated deployments, workload orchestration, and resource management for your services. I set up the platform your development teams ship on: repeatable, auditable, and production-hardened.
Designing and maintaining delivery pipelines from commit to production. Automated builds, environment promotion, and deployment strategies tailored to your workflow. Less manual intervention, faster feedback loops, fewer 2am incidents.
Setting up observability so you see what matters before your customers do. Metrics, logging, alerting, and SLO tracking — the operational layer that turns running software into reliable software.
I'm Daniel Wallat, a Senior Cloud-Native Platform Engineer and founder of rwx Lab GmbH, based in Würzburg, Germany.
Most teams treat building software and running it as two separate jobs. I don't. With 7+ years at the intersection of application development and platform operations, I design services and own them through production — across cloud platforms, container orchestration, and CI/CD pipelines. I've done this for clients in transport & logistics, automotive, insurance, and manufacturing.
Independent consultant, full ownership — from code to production. I work independently through my own company — you talk to the engineer who does the work.

Validates expertise in developing, deploying, and debugging cloud-based applications on AWS — covering core services, security, tooling, and best practices for serverless and container-based workloads.
Verify on CredlyTrusted by engineering teams across industries that don't tolerate downtime. From transport & logistics systems to insurance platforms, from automotive software to manufacturing environments — I've delivered in regulated, high-stakes enterprise settings where reliability is non-negotiable.
Whether you need a Cloud-Native Java engineer, someone to set up your Kubernetes platform, or both — let's have a conversation. I'm available for contract engagements across DACH and remote.
No agencies, no overhead. You talk to the engineer who does the work.
