Hey there! 👋
Welcome to my corner of the web! 👋 I'm a Head of Data Engineering at ODS 🏢 who loves building scalable data solutions 🚀 and empowering software developers 💻. When I'm not architecting real-time datalakes for banking solutions, you can find me diving deep into cloud computing infrastructure (especially AWS) ☁️ or writing code to solve complex problems 🧩. I believe in hands-on technical leadership 🛠️ - you'll find me in the trenches pushing code alongside my team, not hiding behind a management title! 💪 I lead a team of 60 incredible engineers 👥, but I'm one of them first and foremost - debugging, coding, and solving real technical challenges daily 🔍. No pointless meetings 🙅♂️, just practical solutions and working code that delivers results. 🎯
Where I've Worked
In this position I design, create and maintain 100% cloud based (AWS) datalakes all around the globe for different banking solutions. We manage more than 20 AWS holding datalake solutions in different regions.
- Manage the technical team while being part of it: coding, helping in problem resolution and proposing new solutions.
- Design scalable and efficient solutions: POCs are OK but moving to production environments has many other additional challenges.
- Cost optimizations: even though I work for a bank and we have money (:D), I love to design and build cost effective solutions.
- Implemented auto-scaling data processing clusters that handle peak loads while automatically scaling down during quiet periods, saving 40% on compute costs.
- Successfully migrated legacy on-premise datalakes to cloud-native solutions, improving performance by 300% while reducing maintenance overhead.
- Develop 50+ software components and libraries to support data ingestion, transformation, and analysis, ensuring high code quality and maintainability.
- Implemented CI/CD pipelines for data processing workflows, reducing deployment time by 70% and increasing team productivity.
- Designed and implemented a real-time data streaming architecture using AWS Kinesis, enabling near-instantaneous data processing and analytics.
- Many other things to tell...It's been a a great journey during this time!.
My journey here and the skills I picked up along the way previous to Openbank:
- AWS architect: design and implement aws-bases solution for several clients using 30+ AWS services (and yes, 30+ is real. I stopped counting after 32 :D).
- Backend developer (Java, NodeJS, Python)
- Frontend developer: Typescript
- Scripting languages: Python, Bash
- Data Engineering stuff: Apache spark, Distributed real-time processing (Apache Flink), Table formats (Iceberg, Hudi), etc.
- Pentesting: web-based application pentesting (I've reported several vulnerabilities in all the companies I stayed). In my first company I discovered a vulnerability in the mail system that easily allowed an attacker to access any other person just clicking a malicious link
My Learning Path
🚨Spoiler about me 🚨
I must say I'm someone who generally dislikes credentialism. In my opinion, especially in software engineering, a university degree proves less and less over time. I believe people should be evaluated based on what they are capable of building, not by the number of degrees they hold.
My Toolkit
Things I'm good at and tools I love to work with:
Random Facts About Me
Mountain biking. My favorite sport for sure.
I'm not good at skying, but I like it.
As many people in this world, I love visiting new countries.
Discovering new mountains running :)
