Last position:
Platform Engineer at ClimateChoice
In a lean, execution-focused environment, I took ownership beyond a narrow engineering lane, shaping and implementing systems across backend, data, and infrastructure. Partnered directly with the three founders in a fast-moving, high-stakes environment, turning strategic priorities into concrete technical decisions and production outcomes.
- Owned core platform development across backend (Django/Rest Framework/Postgres), ETL (Python/Dagster), infrastructure (Terraform/Kubernetes/AWS), and frontend (typescript/react) for a climate-tech SaaS product, driving continuous cross-stack development across five repositories from October 2021 to this day.
- Architected and owned a standalone internal Python scoring framework for CRC assessments, using YAML-driven rules and metaprogramming to enable non-technical users to define complex evaluation logic without hardcoded implementations.
- Built and stabilized ETL and scraping pipelines using Dagster and Scrapfly, improving document ingestion, tagging, retry behavior, deployment flow, and operational resilience.
- Contributed to platform modernization and reliability through Django/Python upgrades, Postgres/RDS and EKS changes, CDN/TLS updates, test and performance improvements, and observability hardening.
- Drove backend engineering for product features, translating requirements into technical specifications, API contracts, data structures, and scalable implementation plans.

About the technology
Directory foundations
LDAP, or Lightweight Directory Access Protocol, provides a standard way to store and retrieve identity data in a directory. Companies use it for user accounts, groups, devices, application settings and access policies. Its hierarchical model supports central authentication across many systems.
Common implementations
LDAP commonly appears in enterprise identity environments, internal applications, Linux estates and network services. Professionals may work with OpenLDAP, Microsoft Active Directory, 389 Directory Server or directory services provided by cloud and security products. Active Directory uses LDAP alongside Kerberos, DNS and its own administration model.
Integration work
- Connect applications to LDAP authentication and group-based authorization
- Design schemas, directory trees, naming contexts and access rules
- Integrate Linux, Windows, VPN, mail and infrastructure services
- Migrate identities from legacy directories or consolidate multiple sources
- Diagnose bind, lookup, certificate and synchronization failures
Reliable integration requires more than a working login screen. Specialists understand search filters, distinguished names, referrals, service accounts, connection pooling and directory permissions. They also document mappings between directory groups and application roles.
Security and operations
Directory data is sensitive, so secure transport with TLS, least-privilege access and careful credential handling are essential. Strong professionals review anonymous binds, password policies, certificate validation, audit trails and replication design. They can also plan backups, monitoring and recovery without disrupting authentication.
When to hire expertise
- Authentication fails across several applications or locations
- A directory migration must preserve users, groups and permissions
- New services need centralized login and access control
- Replication, performance or schema changes create operational risk
- Internal teams need clear documentation and handover
Companies often bring in freelance expertise for a focused integration, a security review or a migration with a fixed delivery scope. In Berlin, on-site workshops can help with regulated environments and legacy infrastructure, while remote collaboration works well for configuration, testing and documentation.
What strong professionals deliver
Look for specialists who can explain directory decisions in business terms and validate them in a test environment. They should be comfortable reading logs, testing LDAP filters, inspecting packets and tracing authentication across connected systems. Experience with scripting, Linux or Windows administration, TLS, DNS, databases and identity standards adds practical value.
A dependable engagement ends with repeatable configuration, tested rollback steps, access documentation and operational guidance. Strong professionals also separate directory authentication from authorization, define ownership for identity data and leave a clear path for future applications to integrate safely.
Frequently asked questions
Quick answers to the questions that come up most around LDAP.
LDAP is used to access and manage directory information such as users, groups, devices and application permissions. Companies often use it as a shared authentication source for internal tools, servers, VPNs and network services.
LDAP is a protocol for communicating with directory services, while Microsoft Active Directory is a broader identity and management service. Active Directory supports LDAP but also uses technologies such as Kerberos, DNS, Group Policy and domain administration.
A strong LDAP specialist often also understands Microsoft Active Directory, OpenLDAP, Linux, Windows Server, DNS, TLS, Kerberos and identity governance. Scripting and log analysis are valuable for repeatable integrations and faster fault isolation.
The right level depends on the risk and scope. A simple application connection may need focused integration experience, while a migration, replication redesign or security review calls for a professional who has handled directory architecture, testing and recovery planning.
LDAP work is often suitable for remote collaboration when secure access, test environments and clear change procedures are available. On-site sessions in Berlin can be useful for workshops, data-center access, legacy systems or coordination with teams that prefer German or English communication.
Ask for specific examples of directory integrations, migrations or authentication investigations rather than broad claims. Confirm that the professional can document schema decisions, protect credentials, test failure scenarios and explain how permissions are mapped.
LDAP can be a good fit when existing applications, servers or appliances already support directory-based authentication and group lookup. A cloud identity service or modern federation protocol may be preferable for internet-facing access, SaaS integration or passwordless flows, so the decision should follow system requirements.
Quality is shown by secure configuration, predictable searches, clear group-to-role mappings and tested behavior during outages. A capable LDAP professional leaves documentation, monitoring guidance, rollback steps and a controlled handover instead of relying on undocumented fixes.
