Software engineer · Data & AI
Hello, I'm Emanuel.
Software engineer with 10+ years building scalable cloud-native solutions, data pipelines and AI agents.
Currently a data engineer at eMAG, in Bucharest.
About me
What I bring to the table.
Over 10 years, I've built systems that handle millions of events, power real-time decisions, and scale under pressure. My focus: data engineering, cloud-native architectures, and AI agents that turn complexity into competitive advantage.
- Data pipelinesFrom data sources to dbt models, orchestrated in Airflow
- Automation and tool integrationConnecting the tools you already run, DataHub included
- AI agentsBuilt on Claude, ChatGPT and Gemini, with n8n or crew.ai
- Cost optimizationBetter performance from the resources you pay for, at lower cost
Available for project-based remote work.
