Jens R.
Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.
Technologies used: arc42, req42, tpo42, docToolchain, PlantUML, ArchiMate, C4 model, ADR, C, C++ (GTest), CMake, Bare Metal (ARM Cortex-M3/M7), OCI containers, Jenkins, lefthook, Prometheus, Grafana, SBOM, CRA, OPC, SCADA, PLC integration, IPv6 migration, Zero Trust, Sociocracy 3.0, Cynefin

About the technology
What ASN.1 does
ASN.1, or Abstract Syntax Notation One, defines the structure and data types used to exchange information between independent systems. It separates the logical data model from the way that model is encoded for transmission or storage. Companies use it where reliable, compact and formally specified messages matter.
Where it runs
ASN.1 appears in telecom signalling, mobile network protocols, aviation systems, identity infrastructure, automotive communication and public-sector data exchange. In Germany, specialists often support complex systems that must interoperate across vendors, networks and long service lifecycles.
- Define messages, data types and constraints
- Generate encoders, decoders and validation logic
- Integrate protocol specifications into existing services
- Test compatibility across implementations
Encoding and tooling
The right encoding rule depends on the protocol and its operational needs. BER, DER, CER, PER, UPER and OER each make different trade-offs between flexibility, canonical output and compact transmission. Toolchains may include asn1c, OSS Nokalva, Objective Systems products, open-source runtimes and language-specific code generators.
When expertise matters
Companies bring in freelance ASN.1 specialists when a protocol implementation is incomplete, an external specification must be integrated or generated code fails interoperability tests. They also help modernize legacy communication stacks without changing the contract used by connected systems.
- A schema changes and compatibility risks are unclear
- Encoded messages fail against a partner implementation
- Generated code needs review, correction or integration
- Protocol documentation is difficult to turn into working tests
Skills around ASN.1
Strong professionals understand more than notation and code generation. They read ITU-T specifications, model constraints precisely and trace encoding results at the byte level. Useful adjacent skills include C or C++, Java, Rust, network analysis, automated testing, cryptography and continuous integration.
What strong specialists deliver
A capable specialist explains why a schema, tagging choice or encoding rule is appropriate before changing it. They establish test vectors, check boundary conditions and document compatibility assumptions. For remote collaboration, clear packet captures, reproducible builds and shared protocol evidence keep teams aligned; German and English communication may both matter for local projects.
Frequently asked questions
Need clarity? These are the questions we hear most often about ASN.1.
ASN.1 is used to specify structured messages exchanged between systems that may be built by different vendors. It is common in telecom, aviation, automotive, identity and public-sector infrastructure where strict interoperability and compact encoding are important.
ASN.1 supports formal constraints and a broad set of standardized encoding rules, including compact binary formats. JSON is easier to inspect and widely used for web APIs, while Protocol Buffers offers a focused schema and code-generation workflow; the right choice depends on existing protocols, compatibility needs and operational limits.
A strong ASN.1 specialist should understand BER, DER, CER, PER, UPER and OER, including when each is appropriate. They should also know how tagging, constraints, optional fields and canonical representation affect interoperability and test results.
ASN.1 work often connects with C or C++, Java, Rust, network diagnostics and automated testing. Experience with ITU-T specifications, generated code, packet analysis, cryptography or continuous integration is especially useful when the protocol is part of a larger production system.
ASN.1 projects vary widely, so the relevant evidence is previous work with comparable schemas, encodings and integration constraints rather than a generic career label. Ask candidates to explain a real interoperability issue, their debugging method and the tests they delivered.
ASN.1 work is often suitable for remote collaboration when teams share specifications, repositories, test vectors and packet captures. On-site workshops can help with architecture or laboratory equipment, while German or English communication should match the stakeholders and documentation.
Review whether the ASN.1 specialist produces clear schemas, reproducible encodings and tests for constraints, malformed input and version compatibility. A practical review should also cover generated-code integration, error handling and evidence that messages interoperate with the required external implementation.
Bring in an ASN.1 freelancer when a protocol specification must become production code, an implementation fails conformance testing or an internal team lacks encoding expertise. A specialist can also reduce risk during schema changes, vendor integration and modernization of legacy communication systems.
