Hello, World.

I'm Alejandro Nadal.

Software Engineer Data Scientist

More About Me

Let me introduce myself.

Profile Picture

Software Engineer, focused on Data Engineering and Data Science. Fullbright Grantee. I am an Open Source enthusiast, voracious reader and a dedicated professional.

Follow me on:


  • Modern software development practices: As a software engineer, I build software applying OOP and design patterns. I have worked using Agile practices (Scrum, Kanban, planning poker, etc) as well as more traditional methodologies.
  • Teamwork: I have been working in team environments since the begining of my degree and my professional career. I know how to express ideas and disagreements in a constructive way.
  • Bussiness understanding: I have a solid grasp on the business side of the software development process, and I can understand the business requirements of any project. I also possess knowledge about finance and accounting.
  • ETL - Data Pipelines: I can extract and transform data using Pandas, SQL, and Bash, then load it to S3 buckets, SQL databases, MongoDB and DynamoDB. I have experience in maintaining Linux instances, daemonizing processes and scheduling jobs.
  • Machine Learning models: I can choose the right models for any particular situation, and then build and train models using Python, Keras, Tensorflow, Scikit-learn, and Pandas.
  • Model deployment and interfacing: I have deployed trained models into Linux Servers and Serverless functions such as AWS Lambda, manage them and create REST APIs to interact with them in both Node.js and Django. To disponibilize them, I use AWS API Gateway and both traditional Apache web servers.
  • Maths and Statistics: I know how to perform statistical analyisis over data, detect outliers, correlations and create traditional matematical models
  • Backend: I design, create and maintain databases, APIs and microservices in traditional environments such as Linux servers as well as using AWS for the same purpose.
  • Frontend Given a design, I can build a responsive website using React/NextJs and deploy it through Nginx or build it statically to be deployed in S3 or Apache.
  • CICD I have experience automating infraestructure and software deployment to AWS through the Serverless Framework, Gitlab CI/CD and CircleCI.
