Technical Challenges
Let's get dirty with a deep dive in technology.
What technical challenges we accept
First things first: dreitier is not a software development company with any kind of focus on implementing functional requirements in the backend or frontend. If you are searching for a partner implementing your functional requirements, we can recommend you to other companies in our network - but that is not our business.
It gets interesting for us if you need engineering expertise in topics related to your infrastructure or your software development lifecycle and having an impact on your architecture or system design. This can be the development of a custom Kubernetes controller, setting up your orchestration infrastructure, architecting and implementing your Continuous Integration pipeline or the moving your data flow to an Apache Kafka-based message stream.
Our level of expertise
We do not presume to know everything - but we have already seen some.
We categorically rule out challenges that are below layer 3 or at the hardware level. For some cases, we are a good fit, in other we might fit. In the end, it always depends on the specific case whether we can help.
| Scope | We are a good fit | We might fit | That's explicitly not us |
|---|---|---|---|
| Programming language | Java, .NET, PHP | PowerShell, Bash, Go, anything with a stacktrace | Low(er)-level languages like C, Assembler, Rust |
| Framework | Spring, Laravel, Symfony, WordPress | - | - |
| Orchestration system | Kubernetes, SUSE Rancher, Docker | OpenShift | - |
| Cloud environment | AWS, Azure | GCP | |
| CI/CD | Jenkins, GitHub Actions, Argo CD, GitLab | TeamCity | - |
| Infrastructure automation | Ansible | Terraform, CloudFormation | Chef |
| Protocol | Any well-known protocol like HTTP(S), SSH, LDAP(S), DNS, Kerberos | Proprietary or vendor-specific protocols | Protocols without documentation |
| Networking | Proxy issues, latency, ingress/egress issues, TCP/IP | - | Vendor-specific issues (Cisco etc.) |
| Operating system | Linux, Windows | MacOS, BSD | |
| Security | x.509 certificates, TLS, SSO, OAuth, AD/AAD | Restoring backups | Encryption-specific issues, Digital forensics |
| Database | PostgreSQL, MySQL, schema and indexing issues, performance problems | - | Multi-terabyte database clusters |
| Messaging | Apache Kafka, Apache Artemis | Redis | Proprietary products like WebSphere MQ |
