René W.
Last position:
Development of an AI-supported system for lead generation
As part of an in-house development project, a pipeline for automated lead generation was created as the second stage of a preceding system for project monitoring. Based on a list of freelance project URLs (freelancermap), qualified lead records are generated, including company, contact person, official and personal email address, and the appropriate form of address (informal/formal). The technologies used were Python (openpyxl, requests) as well as an LLM agent workflow in VS Code (GitHub Copilot Chat) with a custom slash command and extensive rule set; search APIs (Serper.dev) are connected for research. My tasks included the full concept and development. The core is a rule set of around 480 lines that guides the LLM agent deterministically through extraction, website and email lookup, duplicate matching (against existing provider lists), and the creation of a structured JSON output. Deterministic steps (Excel matching, web/email search, pattern derivation) were moved into Python helper scripts. Other requirements included validating the results through versioned blind runs against a reference, iterative refinement of the rule set, and a swappable search provider layer for cost and stability reasons.

About the technology
What OData does
OData, the Open Data Protocol, is a standard for exposing and consuming structured data through web APIs. It gives applications consistent ways to query, filter, sort, expand and update business data using familiar HTTP patterns. Companies use it to connect business applications without creating a separate interface for every consumer.
Where it is used
OData commonly sits between enterprise data and user-facing applications. Typical use cases include:
- Exposing SAP business data to web and mobile applications
- Connecting Microsoft services, Power BI and business workflows
- Supporting SAP Fiori and UI5 applications
- Creating searchable APIs for orders, products, customers and finance data
- Providing governed access to ERP and CRM information
Ecosystem and tooling
OData work often involves SAP Gateway, SAP S/4HANA, CAP and ABAP, as well as Microsoft Dataverse, Power Platform and .NET services. Specialists may also use OData metadata, service documents, annotations and vocabulary design to make APIs easier for client applications to understand. Testing typically covers query behavior, payloads, authorization and compatibility across OData versions.
When companies need experts
Freelance expertise is useful when an existing service is slow, inconsistent or difficult for consuming applications to use. Companies also bring in specialists during SAP transformations, Fiori rollouts, API modernization and migrations from custom interfaces. In Munich, this can support manufacturing, automotive, logistics and business services while coordinating with local teams or remote delivery groups.
What strong professionals deliver
Strong OData professionals translate business entities into stable service models and keep the contract clear for every consumer. They understand navigation properties, associations, annotations, pagination, filtering and error handling. They also connect API design with authorization, performance, testing and the data model behind SAP or another source system.
How to assess fit
Look for evidence of production OData services, not only familiarity with the protocol name. Ask how the specialist handled query performance, authorization, version differences and changes to underlying business data. Effective collaboration also matters: remote work is practical when documentation is precise, while on-site work in Munich may help when workshops involve German-speaking stakeholders and complex process knowledge.
Frequently asked questions
The facts hiring teams ask for most often when it comes to OData.
OData is used to expose structured business data through consistent web APIs. It supports queries, filtering, sorting, navigation and updates, which makes it useful for SAP Fiori, Microsoft applications, reporting tools and custom web or mobile interfaces.
OData follows REST principles but adds a defined query language, metadata and conventions for describing business entities. REST APIs offer more design freedom, while GraphQL lets clients shape responses through a schema; OData can be a strong fit when discoverability and standardized enterprise queries matter.
A capable OData specialist usually understands HTTP, JSON, XML, authentication and API testing. Depending on the environment, useful adjacent knowledge includes SAP Gateway, ABAP, S/4HANA, CAP, UI5, Power Platform, .NET, SQL and enterprise data modeling.
An OData project may deliver a new service, a redesigned entity model, SAP or Microsoft integration, client-ready metadata and automated tests. The scope depends on the source system, security model, query complexity and the number of consuming applications, so an expert should clarify these before estimating the work.
Ask an OData professional to explain a service they delivered, including entity design, navigation, annotations, authorization and performance decisions. Review whether they document the contract, test edge cases and protect consumers when backend structures change.
OData work is often suitable for remote collaboration because service definitions, tests and API behavior can be reviewed digitally. On-site sessions in Munich can still help with SAP workshops, process discovery and coordination across business and technical teams.
OData is strongly associated with SAP because it powers many Gateway, S/4HANA and Fiori integrations, but it is not limited to SAP. Microsoft uses the protocol across parts of its ecosystem, and other organizations can expose OData services from custom applications and data platforms.
The relevant OData version depends on the source platform and consuming clients. A specialist should check supported query options, metadata formats, annotations, authentication behavior and version-specific features before designing the service, especially when SAP and Microsoft systems must work together.
The average hourly rate of freelancers in Munich, Germany who have used OData in their recent projects is 98 €, which corresponds to a daily rate of about 781 € based on an 8-hour working day.
