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
Open Data Protocol
OData, short for Open Data Protocol, is a standard for exposing and consuming structured data through web APIs. It builds on HTTP, commonly uses REST principles, and gives clients consistent ways to filter, sort, search, expand, and update data. Companies use it to make business information accessible across applications without creating a separate interface for every consumer.
Services and systems
OData services connect business applications with web front ends, mobile apps, reporting tools, and integration workflows. They are common around SAP S/4HANA, SAP Gateway, SAP Business Technology Platform, Microsoft Dynamics, and custom enterprise systems. Typical deliverables include:
- Service design for entities, relationships, and operations
- Read and write APIs for business data
- SAP Fiori and UI5 data access
- Integration with analytics and workflow tools
Ecosystem and skills
Strong specialists understand HTTP, REST, JSON, XML, metadata documents, and the OData query language. Depending on the environment, they work with SAP ABAP, CDS views, SAP Gateway, CAP, Microsoft .NET, ASP.NET Core, or Java-based services. They also know identity, authorization, pagination, versioning, and API documentation.
When expertise matters
Companies bring in freelance OData professionals when an interface must expose complex business rules safely or when existing services are slow, inconsistent, or difficult to extend. Specialist support is useful during SAP modernization, Fiori delivery, ERP integration, reporting projects, and migrations between service versions. In Munich, local teams may value German-language workshops, while remote collaboration works well when service contracts and ownership are documented clearly.
Quality signals
A capable professional starts with the consumer’s needs and models entities around stable business concepts rather than database tables. They define clear metadata, predictable errors, suitable query limits, and authorization rules before writing service logic. Good specialists test filters, expansions, concurrency, and large result sets, then provide examples that other teams can use without guesswork.
Choosing the right specialist
Look for project evidence involving the same back end, service generation approach, and client applications your team uses. Ask how the specialist handles sensitive fields, performance under broad queries, backward compatibility, and monitoring after release. The best fit can explain trade-offs between exposing existing data directly and creating a purpose-built service, and can work effectively with product, security, and business teams.
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 standardized web APIs. Clients can query, filter, sort, expand, and update resources without learning a different interface for every system.
Open Data Protocol adds shared conventions that conventional REST APIs may leave undefined, including metadata, query options, entity relationships, and standard response patterns. A specialist can assess whether those conventions reduce integration effort for your consumers or add unnecessary complexity.
A strong OData freelancer usually brings HTTP, REST, JSON, XML, authentication, authorization, and API testing skills. SAP projects may also require ABAP, CDS views, SAP Gateway, Fiori, UI5, or CAP knowledge; Microsoft work may involve .NET and ASP.NET Core.
The right level depends on the scope, data sensitivity, and back-end landscape. A small read-only service may need focused API experience, while SAP integration or service modernization benefits from a specialist who has handled authorization, performance, versioning, and complex entity relationships.
OData projects are often suitable for remote delivery because service contracts, metadata, tests, and deployment workflows can be reviewed online. On-site sessions in Munich can still help with domain discovery, security decisions, and workshops, especially when several business teams are involved.
OData is often a good fit when clients need predictable entity-based querying, standardized metadata, and strong alignment with SAP or Microsoft ecosystems. GraphQL may suit products needing client-defined response shapes, so the choice should follow consumer needs, governance, tooling, and back-end constraints.
Ask for examples of service modeling, query-performance decisions, authorization design, and automated testing. A quality specialist can explain metadata, filtering, expansion, pagination, error handling, and compatibility in terms that both technical and business stakeholders understand.
SAP OData work often involves exposing CDS views or business logic through SAP Gateway, CAP, or related services for Fiori and other consumers. Freelancers should understand authorization objects, annotations, transport processes, service maintenance, and how SAP release constraints affect design choices.
