Julieta in a few words

I am a software engineer and developer from Argentina.

I am persistent, creative, I love challenges and I seek to continue learning, contributing with my experience and knowledge to the goals of the project I find myself in.

I moved to Amsterdam in 2021 and now I decided that it is time to start freelancing, because I'm responsible of my tasks and I count with lot of experience already. I worked for many industries, so I adapt myself quickly to any kind of project.

I worked mainly in the backend but I have experience working in the frontend, so I consider myself a full stack developer. Although I used tons of languages and frameworks, I like python, Django and Vue.js better. Most of my experience was built using these technologies. However I'm open to learn something new if necessary!

My experience overview would be:
- API definition
- Database structure definition
- Testing
- Experience in dealing with complex business requirements
- Payment service integration: Stripe
- AWS integration: S3
- Email service integration: Sendgrid
- Docker and Docker Compose setup and support
- CI/CD and environments setup: gitlab and GitHub

I also write tech articles in Medium!

Buenos Aires, CF, Argentina

December 2019 - August 2021 (1 year and 8 months)

Online tool for collaborators to fulfill specific tasks, including building customised forms and answering them.

I was the Backend Developer using python Django. I defined and developed the main models (Postgresql) and API (Django Rest Framework) needed for the frontend. My responsabilities included Excel files import and export (pyexcel), PDF generation from HTML (PDFKit), email service integration (Sendgrid), AWS S3 integration to upload files, internationalization.
I also supported the infrastructure development using AWS, Docker and Gitlab CI/CD.


I was the Backend Developer in both e-commerces I worked in, using python and Django. I developed not only the e-commerce backend but also the Admin Panel meant to be used by the client to upload information, 3D images, to mention some. These responsabilities included API definition (Django Rest Framework), payment service integration (Stripe), email service integration (Sendgrid), AWS S3 integration to upload files, models and database definition (Postgresql). In addition to that, I used Django Celery and Redis for some asynchronous tasks related to stock management.
I also supported the infrastructure development using AWS, Docker and Gitlab CI/CD.




Buenos Aires, Argentina

March 2016 - December 2019 (3 years and 9 months)

Platform to connect indie movies with potential users

I worked as a Fullstack Developer using python Django and Vuejs. Although the actual code to upload a large video to AWS was developed by a third- party, me and my team were in charge of developing the rest of the web application. Most importantly the payments and subscriptions, the movie owner panel and an iframe to be embbed in external websites. These responsabilities included API definition (Django Rest Framework), payment service integration (Stripe), models and database definition (Postgresql).
I was also involved in the frontend using Vuejs framework. I connected the frontend by consuming the endpoints we developed in the backend, materialize the designer's mockup to an actual component using the provided styles (CSS), by building the corresponding HTML and writing the necessary Javascript code to make the site dynamic and coupled to the backend. For example: display data in Google Charts, show diverse written information, trigger backend tasks by consuming the right endpoints, among others.



Ad-honorem professorship

Buenos Aires, CF, Argentina

April 2014 - December 2015 (1 year and 8 months)

I was involved in the creation and correction of assignments, exercises and exams.
I have been also in charge of the explanation of some topics in class and I have mentored several students by email
Subjects: Programming Paradigms and System Design.

Sandro Manuel Damilano Maison - UTN FRBA


She has always performed her tasks very professionally. Clear explanations and quick corrections were a given. She was also deeply committed to every student she had to tutor, both online (emails, web campus) and offline (before or after lectures). She has been an excellent teacher, mentor and colleague overall, one that every classroom would definitely benefit from.

Mariel Guadalupe Vargas - Ibisdev


I had the opportunity to work with Julieta on very challenging projects and, honestly, she has not only been able to achieve the goals, but has gone further, proposing improvements and new ideas for the products she developed and for the team in general. Beyond that, Julieta is a great person, with whom it is a pleasure to work.

Leonardo Santa Cruz - Ibisdev


Working with Juli was a very satisfying experience for many reasons. For me, the main one could be the excellent connection we developed as a team and also how quickly she used to find out a solution for each problem. I would definitely recommend working with her.

Gaspar Habif - Kavak


I shared with Juli several projects in which she stood out not only for her great technical skills, but also for her predisposition, her proactivity and her pragmatism. In those projects she lead the backend using mainly Django, but she didn't doubt when having to help her partners with the infrastructure (Everything Docker based) or with the frontend (VueJS). I think she is the best choice you can make if you need someone responsible with pretty good delivery, to deal with some challenging tasks.
