Christoph T.
Last position:
Backend Software Developer (Java) at German Football Association (DFB) e. V.
- Client: Prime Force Group GmbH
Technologies used: Java 25, Spring Boot 4, MapStruct, JSpecify, PostgreSQL, Redis, Liquibase, REST/OpenAPI, Apache Kafka, Apache Solr, OpenID Connect via IronGate/Keycloak, SAP Customer Data Cloud, JUnit, Testcontainers, Karate, Playwright, GitLab monorepo with CI/CD, Jenkins, JFrog Artifactory, FluxCD, Docker, Kubernetes on Azure, OpenTelemetry, arc42, Jira, Confluence
The Team Management Center is the new central platform of the DFB for planning, managing, and carrying out team activities for the national teams - from squad selection and training camps to communication with players, clubs, and legal guardians. The platform is designed for multi-tenancy for the DFB and regional associations; player, club, and master data are intentionally not copied, but connected at runtime via the DFBnet APIs.
I have been involved in the project continuously since the architecture and concept phase (Sprint 0) and work in a distributed Scrum team in two-week sprints. In addition to implementation, my focus is on architecture alignment, connecting the DFBnet interfaces, as well as code reviews and test automation as quality assurance in the team.
Focus areas:
- Development and implementation of the multi-tenancy concept (tenant model for the DFB and regional associations), including data model, access layer, and Liquibase migrations.
- Design of the person service and the search concept based on Apache Solr.
- Integration of the DFBnet APIs (player, person, and club search, club data), including authentication and synchronous master data synchronization.
- Hardening the integration through resilience patterns: separate read timeouts for each search path, correction of circuit breaker counting, limiting parallel requests, and a club cache to reduce load on the external system.
- Development of self-service endpoints for players (own activities, activity details, games), including an access concept for participants, as well as person documents and file uploads.
- Standardization of API design: OpenAPI annotations, nullability model via a custom ModelConverter, JSpecify migration of the DTOs, and documented API guidelines.
- Build and maintenance of Karate-based API and integration tests, integration tests with Testcontainers, test guidelines, and bug triage from the integration and reference environments.
- Code reviews via merge requests, architecture documentation according to arc42, and architecture decisions (ADRs) in Confluence.
- Automated deployment to the integration and reference environments, analysis of login and OIDC issues in combination with IronGate.
Status: ongoing - as of 08/2026 in Sprint 17, around 940 person hours worked; testable delivery to the integration environment every two weeks.

About the technology
What Digital Signature means
A digital signature uses cryptographic methods to confirm who signed a document and whether its contents changed afterward. It is more than an image of a handwritten signature: certificates, keys and validation data create a verifiable link between the signer and the signed file. Companies use it for contracts, approvals, forms and regulated records.
What companies build
Digital signature specialists create workflows that move documents from preparation to signing, validation, storage and audit. Typical use cases include:
- Customer and supplier contracts
- Employee and HR documents
- Procurement and invoice approvals
- Insurance, banking and public-sector forms
They also define signing order, reminders, identity checks and rules for rejected or expired documents.
Ecosystem and tooling
Projects may use DocuSign, Adobe Acrobat Sign, Dropbox Sign or qualified trust service providers. Specialists work with PDF standards, X.509 certificates, public key infrastructure, REST APIs, webhooks and identity providers. Integrations often connect signature services with Salesforce, SAP, Microsoft 365, document management systems and custom applications.
When freelance expertise helps
Companies bring in freelance specialists when a signing process must replace email attachments, connect several business systems or meet strict audit requirements. Germany-based teams may also need support aligning workflows with European trust services and internal compliance policies. Remote work suits API design, configuration and testing; workshops and rollout support may benefit from on-site collaboration and German-language communication.
Skills that matter
Strong professionals understand both cryptography and business processes. They can distinguish simple electronic signatures from advanced and qualified signatures, select suitable identity checks, and document certificate ownership and validation. They test rejected signatures, changed documents, expired certificates, time stamps, access rights and audit trails instead of treating the visible signature as proof of quality.
Choosing the right specialist
Look for experience with the exact signing scenario, document volume, identity model and systems involved. A good specialist asks where documents originate, who must sign, how consent is recorded and how long evidence must be retained. Before delivery, expect clear workflow diagrams, integration documentation, security decisions, test cases and a practical handover for legal, IT and operations teams.
Frequently asked questions
Questions about Digital Signature? Start with the answers below.
Digital Signature technology verifies a signer’s identity and shows whether a signed document was altered. Companies use it for contracts, approvals, onboarding, procurement, invoices and records that need reliable evidence of consent.
A digital signature relies on cryptographic certificates and keys to protect document integrity and support signer verification. An electronic signature is a broader category that can include typed names, click-to-accept actions or drawn marks without the same technical controls.
A strong Digital Signature specialist often understands PDF processing, PKI, X.509 certificates, REST APIs, webhooks and identity management. Experience with DocuSign, Adobe Acrobat Sign, SAP, Salesforce or Microsoft 365 can also be important when the workflow crosses business systems.
The right Digital Signature professional depends on the risk and integration scope, not a fixed tenure requirement. A simple configuration needs workflow and vendor knowledge, while a regulated rollout may require experience with certificate lifecycle management, qualified trust services, audit evidence and complex identity checks.
Digital Signature projects are often suitable for remote collaboration because configuration, API work, documentation and testing can be completed online. On-site workshops may still help with German stakeholders, process mapping, security reviews and rollout training.
A Digital Signature specialist should compare identity verification, signature types, regional trust requirements, API limits, document storage, audit trails and integration fit. The best choice depends on the signing risk, existing systems, user experience and control the company needs over data and certificates.
Reliable Digital Signature work includes valid certificate chains, protected keys, trustworthy time stamps and evidence that detects document changes. The specialist should also test failed, withdrawn and expired signatures, record consent clearly and provide an audit trail that operations and compliance teams can understand.
Before accepting a Digital Signature assignment, clarify the document sources, signing order, identity method, required signature level, retention rules and target integrations. Ask who owns certificates and keys, which countries are involved, how exceptions are handled and what the final handover must contain.
