Senior Data Scientist/ML Engineer

$8000 / mo
≈ $96000 / year net

Spain · 5 years of experience · B2 - Upper Intermediate · Published today · In passive search

I'm a Data Scientist/ML Engineer with a strong analytical foundation and a product-oriented mindset. I specialize in building and deploying machine learning models that solve real business problems — LTV and churn prediction, user segmentation, experiment evaluation etc.

Over the years, I've worked across the full lifecycle of DS projects: defining problems with stakeholders, analyzing data, building and validating models, deploying them into production, and setting up pipelines and monitoring to keep them running. I’m comfortable working with both data science and data engineering tools — and I believe in writing clean, reproducible, and maintainable code.

I’m equally fluent in business conversations and technical deep dives. My goal is always the same: deliver insights and tools that actually move the needle.

Languages & Core Tools:
Python, SQL

Experimentation & Analytics:
A/B testing, cohort analysis, statistical testing, product metrics

Data Engineering & MLOps:
Airflow, Git, Docker, dbt, Terraform, AWS (Glue, S3, SageMaker), CI/CD basics

Visualization & Dashboards:
Streamlit, Looker, Superset, Tableau

What I Bring to the Table
1) Ability to ship practical ML solutions end-to-end — from data prep to deployment
2) Deep understanding of analytics and experimentation in real products
3) Comfortable working in fast-paced, cross-functional teams
4) Passion for clean, maintainable code and well-structured pipelines
5) Clear communication of complex results to both tech and non-tech stakeholders

I`m the founder of the project Gradus Dobra. We organize workshops for youth with disabilities on making eco-friendly candles. Our main project partner is NGO “Family for persons with disability”, which is a youth center for persons with mental or physical disabilities and their families.

My project aims to achieve two goals: help persons with disabilities to socialize and be able to bring their impact into the community and teach people how to reduce cans and glass bottles waste by making candles. Every Saturday we teach the participants how to create candles using metal cans and cut glass bottles as a candle containers.

Every time we include new volunteers in these workshops, so young people can not only maintain valuable skills but also communicate and become acquainted with other people. Moreover, it is common that persons with disabilities require significant spendings on supporting their health, so we plan to organize a fair where our participants can sell their products and receive both financial and mental support.
