MY FAVOURITE TECH STACK

Here's what I enjoy working with ...

DJANGO and JAVASCRIPT

I build stuff mainly with JavaScript and Django. I guess all Django developers share a common story. They built a lot of stuff, tried a micro-framework, but in the end, they always returned to Django because it is opinionated, and offers all the tools for building full-stack web applications with Python.

Despite my crush for JavaScript on the frontend, Django and Postgres are my safe harbors for anything backend related.

TESTIMONIALS

Consulting

Valentino is a very high level professional.

It provided its expertise as a team leader on a project based on Django and React. Needless to say, it really made a difference. I was very pleased and admired in the way he brought new teaching and best practices of the highest value.

Excellent cooperation even on the human profile and mutual confrontation.

I want to express my appreciation for the wonderful work and the excellent service that Valentino has done.

He supported us in migrating our old full-stack PHP website to a new and more efficient ReactJS app.

Our team of PHP experts has been guided by him in the most appropriate choices and directions, saving a lot of precious time in the search for the best practical solutions.

Always available and friendly, Valentino has proven to be very professional and technically well informed.

I was looking for a consultant who could help us with the strategic choice of front-end technologies for our products.

I stumbled on Valentino's blog, got in touch, and hired him for advice.

With great professionalism and passion he helped shaping our journey toward new technologies.

Feedbacks from developers I trained

Valentino is a great trainer and mentor. He's flexible in his approach and tailors it to learner's needs.

What's appealing about his style is that not only he shows you "how" but also "why".

If you are looking to get up to speed or solidify your understanding, I would highly recommend Valentino.

I was looking for a teacher who could help me to start with React/Redux and I found Valentino. I had the first 10 lessons with him where we were able to cover a lot of very interesting aspects of React and Redux (in order to start with them we had also a look/refresh on JavaScript concepts).

After the first 10 lessons, I decided to extend the course with another 5 lessons, that were dedicated to a better understanding of particular topics that I have raised . I'm very happy of him and his approach: I would definitely recommend Valentino!

After years of online courses I was still feeling insecure when writing code and logic. But thanks to the training path I took with Valentino now things start to be crystal clear.

Valentino prepares a personalized path for every student, and you learn something new in every lesson.

I suggest Valentino's training to anyone feeling insecure about programming in general and JavaScript. It's the best way to learn.

Great teacher.

I like the assignments so much, they are focused on solving real practical problems with React.

The assignments are never trivial, they require an effort which helps to internalize the concepts.

Being coached with a personalized learning path is very useful and helps saving plenty of time!

I always studied JavaScript as a self-taught developer.

Then I decided to contact Valentino because I felt I had to dig deeper into the intricacies of JavaScript.

Valentino is able to explain JavaScript clearly, adapting the study plan to my needs.

The exercises are great too, and they help sticking JavaScript in my head. Great teacher! Recommended!

Valentino is not only a JavaScript and React expert, but also has the required ability to clearly transmit this knowledge.

He attributes great importance to testing, a field in which few have comprehensive knowledge.

He is a great teacher, and I would highly recommend him.

Valentino is a great teacher! He is professional and prepared. He makes every topic clear and understandable. The lessons are relaxed and focused on guiding the student to clearly understand the concepts.

I've spared not less than 6 months of study and research on Redux thanks to him!

Hi!

I am Valentino and I help busy people embracing this crazy modern JavaScript stuff.

I'm also active in the Python community and I serve as a coach for Django Girls.

PYTHON MEETUP FIRENZE 2020 - AVVENTURE ASINCRONE CON DJANGO Q

Django è un framework così completo che quasi non sembra vero. Ma i problemi iniziano dopo, quando Django stesso impone di usare strumenti come le task queue.

PYCON IT X 2019 - DECOUPLING DJANGO WITH DJANGO REST (AND A SPRINKLE OF REACT)

With the rise of JavaScript as the lingua-franca of the web and the steady growth of libraries like React, today’s web developers can build rich and well structured frontend experiences. Pair that with Django and Django REST framework and you get the perfect combination.

But it’s not all bells and whistles. What challenges are we going to face when decoupling Django with Django REST? What are the best practices? How to structure such a project? In this talk I’ll guide Django developers (both beginners and intermediate) from 0 to structuring a decoupled Django project.
