OBJECTIVE
Aspiring Data Engineer with hands-on experience in SQL, Python, and data integration using PostgreSQL. Recently
completed a 9-month certification program focused on modern data engineering practices, including ETL development,
cloud fundamentals (AWS), and data quality techniques. Brings a strong analytical mindset and attention to detail from prior
IT experience. Eager to apply technical skills in building reliable, scalable data solutions within a collaborative team
environment.

EXPERIENCE
Data Analytics Engineering training program, EPAM, Remote, Oct 2024 – Jun 2025
Built a complete end-to-end data engineering solution simulating a real-world enterprise pipeline, from raw data ingestion
to BI visualization. The program covered modern data practices including cloud services, data quality controls, and scalable
ETL design.
Key Accomplishments:
• Designed and implemented a normalized relational schema (3NF) in PostgreSQL to support 10+ business metrics
• Developed modular ETL pipeline in SQL with incremental loading, logging, and error handling reducing data refresh
time by 60%
• Built a multi-layer architecture: staging, ODS, DWH, and data marts
• Implemented robust data quality checks at each pipeline stage, ensuring 100% consistency between source and
reporting layers
• Created an interactive Power BI dashboard with multi-page layout, KPIs, DAX logic, filters, and RLS
• Used AWS services: EC2, S3, Glue, Athena, Redshift and Lambda to deploy the same project in cloud

Manual QA Engineer, NIX Ukraine, Kharkiv / Poltava, Jan 2022 – Jul 2024
Worked on a large-scale Vendor Management System, contributing to feature development and system maintenance
through comprehensive manual testing and UI/UX validation.
Key Accomplishments:
• Performed functional, UI, and regression testing across core modules (staffing, billing, localization)
• Verified database jobs and workflows during migration from Oracle to PostgreSQL
• Documented edge case scenarios and contributed to improving test coverage with overall record 500+ test cases
• Mentored new QA engineers and led onboarding sessions
