What I'm looking for

I’m focusing on Backend and Data Infrastructure roles, ideally remote across the EU/US or based in Spain. I’m open to B2B contracts and Autónomo arrangements.

At NDA Client | Global Financial Analytics Company, I engineered serverless ingestion with AWS Lambda and S3, plus FastAPI event collection endpoints for a digital marketplace handling 600k+ daily transactions. I also built resilient Airflow, dbt, and AWS Glue pipelines for downstream data warehouse services.

At Melodiya Zdorovya, I developed PostgreSQL and RabbitMQ integrations connecting retail systems with Yandex Eats/Delivery, supporting a sales channel that drives ~10% of company revenue. I also maintained a PostgreSQL warehouse with 400M+ row fact tables and automated financial reconciliation across 2,000+ stores.

Earlier, at CDEK Digital, I developed Django REST APIs and Kafka streaming pipelines for distributed services handling 200k+ daily transactions. I’m focusing on Backend and Data Infrastructure roles, and I’m open to B2B contracts and Autónomo arrangements in the EU/US remote market or Spain.
