Go & Distributed Backend Systems
Over 15 years of experience building and running distributed backend systems, with Go as the primary language. Expertise in gRPC/Protobuf, REST/OpenAPI, API design and versioning, as well as Event-Driven Architecture, Domain-Driven Design and Clean Architecture.
Data, SQL & Streaming
Deep knowledge of PostgreSQL including schema design, query tuning and transactional concurrency control, as well as CockroachDB, Oracle and MySQL. Experience with Redis, Elasticsearch, MongoDB and event streaming platforms such as Kafka, NATS and RabbitMQ.
Cloud & Infrastructure
Certified Kubernetes Application Developer (CKAD) with hands-on experience in Kubernetes, Docker and Helm. Proficient in Google Cloud Platform, AWS (ECS, EC2, S3, RDS, Lambda, SQS), Terraform, HashiCorp Vault and CI/CD pipelines using GitHub Actions and Jenkins.
Performance & Reliability Engineering
Load, smoke and performance testing before release, including latency and throughput tuning. Monitoring with Prometheus, Grafana, OpenTelemetry, distributed tracing and Splunk. SLO-minded alerting, incident runbooks and on-call support.
Java & Kotlin Development
Extensive experience with Java and Kotlin using Spring Boot and Spring Cloud for building microservices and backend systems in production environments.
Testing & Quality Assurance
Proficiency in TDD/BDD, integration and contract testing with Pact. Experience designing BDD-style test suites that serve as executable specifications and catch mismatches between code and requirements before release.
Observability & Monitoring
Setup and ownership of observability stacks using Prometheus, Grafana, OpenTelemetry and Splunk. Creation of dashboards, alerts and incident runbooks to ensure production readiness from day one.
Team Leadership & Mentoring
Experience leading and mentoring teams of developers in clean code practices, Domain-Driven Design and Event-Driven Architecture. Conducted PR reviews and guided junior developers in idiomatic Go.

Projekthistorie
Contributed to the Quota Service, a Go/gRPC service on the critical path of every provisioning and Managed Kubernetes request. Enforced quota correctness in PostgreSQL across stateless replicas on Kubernetes. Wrote load-testing and smoke-test scripts, owned production readiness including Prometheus metrics, distributed tracing, dashboards, alerts and incident runbooks. Shipped the MVP on schedule, refactored components toward Domain-Driven Design and mentored junior developers in idiomatic Go.
Designed a scalable modular monolith with event-driven (Kafka) and serverless components, defined REST API contracts and integrated third-party services. Cut cloud infrastructure costs, built CI/CD pipelines with Terraform-managed infrastructure and SonarQube quality gates, set up observability with OpenTelemetry, Prometheus and Grafana, and led a team of 5 developers.
Designed and built a cross-currency outbound payments service in Go on an event-driven platform (NATS). Ran comprehensive performance testing, built monitoring dashboards and alerts for on-call engineers, and improved the testing suite cutting test runtime by up to 20%.
