- Jumbo Argentina. First project assignment

https://www.jumbo.com.ar

The project assignment consisted in implementing an e-commerce site under the VTEX platform.

The site was successfully launched and for the following months after the first release I remained an active part of the team leading the maintenance of the site.

- Support & Maintenance

After becoming one of the referrals within the front-end area, I was assigned, along with my main assignments, to collaborate in the coordination and maintenance of several productive projects that required support and new features developments.

I've mantained several e-commerce sites:
https://www.wong.pe
https://tienda.personal.com.ar
https://www.crateandbarrel.com.co
https://www.crateandbarrel.com.pe
https://www.sportline.com.ar
Delivering optimizations and new features.

- Vtex Ecommerce Template

As part of the company's front end referral team I took part on developing the company e-commerce site template based on VTEX platform. The main goal was to ensure that any member of the front end team can be able to implement an e-commerce site in VTEX in less than 1 month.
To achieve this we decided to build a template that was easily replicable and that already had a basic configuration to deploy it to production as soon as possible.

The result was a complete success. Not only was I able to be part of building a template from scratch and with a modern technological stack, but also the assumptions were fulfilled and we achieved that any member of the team could implement a new store in 2 weeks. Some of the sites implemented with the template are:
https://www.mote.com.uy
https://www.comodinencasa.com.ar
https://www.geant.com.uy
https://www.tata.com.uy
https://www.hiperlibertad.com.ar
