Writing about ML, Python & software craft
Hi, I'm Teo Parashkevov
Machine Learning Engineer & Senior Python Developer
I design and build scalable software systems that put machine learning to work, from data pipelines and model training to clean, production-ready Python. This is where I share what I learn about AI, data and software engineering.
What I do
Where I focus
Three areas I keep coming back to, both in my day-to-day work and on this blog.
Software Engineering
Designing scalable, robust and efficient software with a focus on performance, clean architecture and maintainable code.
- Python
- Design patterns
- Clean code
Data Analysis
Data preprocessing, exploratory analysis and statistical modeling that turn raw data into insight and data-driven decisions.
- Pandas
- NumPy
- SQL
