Diego Martin Mármol
Senior Front End Developer at DataArt
Buenos Aires, Argentina
I'm a FullStack software developer specialized in Frontend UI. I have a solid background based on years of work creating business oriented web apps mainly using ReactJs as the base library behind them. I consider myself an active and constantly motivated guy that wants to learn everything all the time. Although sometimes a bit obsessed with perfection, I'm in constant movement towards growing as a professional by staying up to date with modern technologies and every-day-changing standards.

Senior Front End Developer
Sep 2020 - Present (3 years 7 months)
My responsibilities involve maintaining and developing features over the UI of a Frontend App as well as extending an API for an internal service that acts as a middleware between the Frontend and the Backend, a "Back end for Front End" (BFF). A few libraries and tools I'm using right now are:
- Typescript & ES6
- React (using hooks and avoiding Class components)
- React Context as State Machine system
- NextJs for Server Side Rendering
- NodeJs + Express

eCommerce: Web & Mobile application
Feb 2021 - Jun 2022
LATAM Retailer
eCommerce platform build for important retailer in LATAM
Worked with a team of Web & Mobile developers focused on Frontend with minor interference on Backend tasks using ReactJS and NodeJS respectively as the primary tech stack.
I was in charge of developing and maintaining the UI as well as adding new features to the eCommerce.
Such features involved:
- UI components development
- Performing http request to retrieve and display data (CRUD operations)
- React Hooks driven side effects (since we weren’t using redux, we focused our side effects architecture through the use of react hooks)
- BFF (backend for frontend) development using NextJS backend layer as a middleware
- Performance optimization through Google Lighthouse
- Unit-test including component unit testing
- In depth Code Review in order to maintain good practices and standards across the app
- Development was mainly focused in functional programming

Frontend & BackEnd for a Catalog web app
Sep 2020 - Feb 2021
Important Retailer app from LATAM
I was in charge of maintaining the UI as well as adding new features to the catalog. Such tasks involved prior research, communication with the product manager and the business analyst as well as proper testing after the development of the feature.
The main requirement for this interface was to provide a smooth UX to the users in order to massively update more than 10k products per operation through large .csv files. This led us to making each transaction as performant as possible as well as providing clear feedback to the user while their process was still running.
The most challenging aspect I found for this project was that our app needed to integrate and co-exist with a huge list of existing API's that were simultaneously consumed by many other apps from other small teams like ours in what hierarchy matters. This lead to the development of a BFF (BackEnd For FrontEnd) layer build using Nodejs + Expressjs that acted as a middleman in between the FrontEnd and the existing APIs requesting data from it and returning the desired format for our app.
