Last position:
Senior Software Engineer — AI Evaluation & Benchmarks at Diversido
- Provided technical leadership for a 4-engineer team delivering 3 major client platforms in 12 months with microservices architecture and scalability solutions — 100% of scoped majors shipped ahead of schedule vs. planned milestones (baseline: prior releases often slipped 1–2 sprints).
- Ran AI model evaluation and model outputs evaluation on LLM/AI vendor APIs: safety, completeness, instruction adherence, and groundedness review before go-live; cut escaped bad outputs in AI-integrated release checklists from recurring UAT findings to near-zero on final promote.
- Drove API development and performance optimization for payment, exchange, and AI services; fail-closed error handling and payload validation reduced integration rework cycles by ~35% vs. the first AI integration pass.
- Applied software testing, testing frameworks, code quality assurance, and code refactoring with continuous integration gates; first-pass PR acceptance improved across the team and production hotfixes on AI adapters dropped noticeably after review standards landed.
- Owned DevOps practices: Docker, GitHub Actions, Jenkins-compatible pipelines, and version control workflows — cut deployment time ~50% vs. pre-automation baseline and stabilized releases across 3 client environments.
- Implemented verifier/oracle-style pass-fail checks in container sandboxes (Harbor/Terminal-Bench aligned); wrote technical documentation so failures cleared in one review cycle.
- Led cross-functional collaboration with product and client stakeholders; translated AI evaluation scores and risk findings into plain-language briefs for non-technical partners, unblocking go/no-go decisions without extra engineering meetings.
- Used agile methodologies for sprint planning and backlog ownership; mentored engineers so mid-level contributors owned AI adapter modules independently by mid-engagement.

About the technology
Private Registry Core
Harbor is an open-source registry for container images and other cloud-native artifacts. It adds authentication, role-based access, project isolation, vulnerability scanning, replication and audit controls around OCI-compatible repositories. Companies use it to keep build outputs under control while moving workloads safely into Kubernetes and other container environments.
Security Controls
Harbor helps teams enforce trust before an image reaches a runtime environment. Strong specialists configure Trivy-based scanning, content trust where required, retention policies, immutable tags, robot accounts and project permissions. They also connect Harbor with LDAP or OIDC identity providers and define response paths for critical findings.
Ecosystem and Tooling
Harbor sits in a wider delivery chain rather than operating alone. Relevant expertise often includes:
- Docker and OCI image workflows
- Kubernetes, Helm charts and private chart repositories
- CI/CD with GitLab, Jenkins, GitHub Actions or similar tools
- S3-compatible storage, PostgreSQL and Redis dependencies
- Prometheus metrics, logs and operational alerting
Where It Runs
The registry can run on dedicated infrastructure, in a virtualized data center or on a managed Kubernetes cluster. It supports disconnected and restricted environments where image provenance, local availability and controlled promotion matter. In Germany, specialists may support regulated industries, manufacturing, public-sector systems and enterprise platforms, working remotely or alongside local infrastructure teams.
When to Bring in Expertise
Freelance support is useful when a company is replacing an insecure registry, introducing Kubernetes, consolidating fragmented image stores or preparing Harbor for production. Typical assignments include architecture, installation, migration, upgrade planning, backup design and integration with delivery pipelines. Experts can also investigate failed pulls, storage growth, certificate issues and replication delays.
Signs of Strong Specialists
The best professionals understand both registry behavior and the systems around it. They can explain how a proposed design affects storage, network paths, credentials, recovery and developer workflows before making changes. Look for practical evidence in:
- Secure image promotion from build to runtime
- Reliable backup, restore and disaster-recovery tests
- Clear access models for teams, robots and external registries
- Measured troubleshooting of scanning, replication and performance
- Documentation that another operations team can maintain
Frequently asked questions
Quick answers to the questions that come up most around Harbor.
Harbor is a private registry for container images and other OCI artifacts. Companies use it to store, scan, sign, replicate and control access to software packages before they are deployed to Kubernetes or other runtimes.
Harbor gives companies more direct control over registry hosting, project permissions, replication and security policies than a public registry. Cloud registries can reduce operational work, while Harbor is often preferred when data location, disconnected operation or a consistent multi-cloud setup matters.
A strong Harbor specialist usually understands Docker and OCI standards, Kubernetes, Helm and CI/CD systems. Useful supporting skills include Linux, TLS certificates, LDAP or OIDC, object storage, PostgreSQL, Redis, monitoring and backup operations.
The right level depends on the assignment. A simple repository integration may need focused registry experience, while a production rollout benefits from a specialist who has handled migration, high availability, storage planning, vulnerability scanning and disaster recovery.
Yes. Harbor work is often suitable for remote collaboration because configuration, pipeline integration and documentation can be handled securely through controlled access. On-site sessions can still help when the registry connects to restricted data-center networks or hardware that cannot be reached remotely.
Harbor is well suited to restricted environments when its images, dependencies and update process are planned carefully. A specialist should design controlled import and export procedures, local scanning, certificate management and recovery tests rather than treating the registry as a simple file store.
Ask the specialist to explain a complete image path from build to deployment, including permissions, scanning, promotion and rollback. Good answers cover failure handling, backup restoration, storage behavior and auditability, not only installation commands.
A typical Harbor engagement can include an architecture decision, deployment configuration, identity and access model, CI/CD integration, migration plan and operational runbook. It should also define monitoring, upgrade steps, backup validation and ownership for ongoing maintenance.
