'Is life about what you accumulate or how you contribute?'
Hi there, welcome! I'm Asier, a software engineer who loves building things that make a difference. Whether it's architecting data pipelines or developing personal projects, I'm always driven by curiosity and the desire to create something useful.
Currently, I'm working as a Data Engineer with 8 years of experience, focusing on building scalable cloud-native solutions that turn complex data into meaningful insights.
About Me
Hello! I'm Asier, a Data Engineer with 8 years of experience in software engineering. Over the last few years, I've specialized in building scalable data architectures and leading cloud-native projects that solve real-world problems.
My journey began with a dual degree in Computer Science and Business Management at Universidad Carlos III de Madrid (UC3M). Since then, I've navigated through various roles—from DevOps and Backend Engineering to my current focus on Data Engineering.
Recently, I've been contributing to a massive cloud migration of billions of rows at Ultra Tendency, leveraging modern technologies like Airflow, PySpark, and Apache Iceberg. Additionally, I have contributed as an independent consultant on a high-impact electricity project, providing comprehensive analytics through cloud-native solutions.
Here are a few technologies I've been working with recently:
- Python
- Spark / PySpark
- SQL / NoSQL
- Cloud Services (AWS, Azure, GCP)
- Terraform / IaC
- Airflow
- Kubernetes / Docker
- Java / Scala
- Databricks
When I'm not at my desk, I'm usually out exploring the mountains, learning about finance and geopolitics, or in the kitchen experimenting with new recipes. I also enjoy working on home renovations and DIY projects 😄

Some Things I’ve Built
Featured Project
Deily
Developed a high-performance, automated news curation platform that delivers personalized content to users via email. The system uses semantic analysis to match global RSS feeds with specific user interests, moving beyond simple keyword matching to understand the context of news stories.
Key Technical Achievements:
- Semantic Matching Engine: Integrated OpenAI Embeddings to calculate cosine similarity between article content and user-defined topics.
- Intelligent Deduplication: Built a custom pipeline that identifies and filters redundant news stories, reducing database noise by over 40%.
- Automated Pipeline: Designed a robust background processing architecture using FastAPI and scheduled tasks for RSS fetching and text normalization.
- Admin Monitoring Suite: Developed a dashboard to track system health, user growth, and operational metrics.
- Internationalization (i18n): Implemented full multi-language support (English, Spanish, French) across the UI and email templates.
- Python (FastAPI)
- React
- OpenAI
- PostgreSQL
- Redis
- Tailwind CSS
