Data Excellence · Business Intelligence · Data Quality

Hi, I'm Denizcan Güney.

Business Informatics student at HWR Berlin. I work at the intersection of data, BI and IT-driven processes — with experience in data quality, reporting and data-driven product management.

Projects (selection)

A selection of concepts and applications that reflect my work at the intersection of data, products and processes.

Identity Verification Platform (in development)

A B2B identity verification service that lets companies run KYC-style document and biometric checks through an API instead of building that pipeline themselves. Clients send ID documents and a selfie (including live camera capture on web and mobile). The platform extracts document data, checks the machine-readable zone, runs quality and fraud heuristics, compares the document photo to the selfie, and returns a structured decision: approve, decline, retry, or send to manual review. Results can also be delivered asynchronously via webhooks. Operators get a tenant-scoped dashboard for sessions, API keys, audit history, and GDPR-style export/erasure.

Modular API core with a decision pipeline (document analysis → biometric checks → final verdict), a web dashboard for operators, and capture clients for browser and mobile. Multi-tenant by design: data, keys, and media stay isolated per customer. Privacy-first: encrypted storage, retention/deletion, and audit logs without raw PII in operational output.

About me

I am a Business Informatics student at HWR Berlin and currently completing a mandatory internship at Robert Bosch GmbH in Data Excellence / Business Intelligence. There I develop data quality monitoring, historized analyses and Power BI reporting for CAFM and enterprise data.

Previously, I worked in product management at Jelbi (BVG), focusing on fraud monitoring and data-driven product improvements. I combine technical and business perspectives and am particularly interested in data quality, BI, efficient processes and data-driven decisions.
