Stefan Chelcea

Data Quality and Technical Data Analyst with 4+ years of hands-on experience in high-volume dataset validation, multi-source data normalisation, and structured data integrity management within a live B2B data product environment. Background in Electrical/Electronics Engineering provides a first-principles analytical layer, with physical system logic applied directly to catch structural data errors that standard QA processes miss. Proven track record of sustained throughput outperformance (30% above target), zero client-reported data failures, and autonomous ownership of complex data domains. Fluent in English (C1). Currently expanding into Python-based data automation (University of Helsinki MOOC). Available immediately for fully remote roles.
