Website oliveralonso.dev

Perfect understanding of products lifecycle. Deep knowledge of Software Architecture and design patterns.

High experience in JS technologies: Typescript, Node/Express, React, GraphQL/Apollo/Knex, Emotion/Styled/CSS in JS.

Love to have a well tested codebase using Jest/testing-library/supertest for unit/integration testing and Cypress for e2e using a BDD methodology.

Passionate about sports. Occasional writer and tertullian in podcasts. In my free time, I love to go with my wife and my dog to the beach, play American football, read tech and non-tech books, and listening music (Red Hot Chilli Peppers is my fav band 🌶️).

Know-how

Product oriented

My career has been coupled of startups in different stages so I had the experience of being the very-first developer in-house but also working for a 400-employee company. That gave me different views of startups and an understanding of the company's needs at each moment.

Full-Stack

Always worked in this kind of position to contribute to all layers of development. I would highlight NodeJS with MySQL in the Backend, GraphQL/Node/Express in the middle and Javascript/React with Styled/Emotion/CSS in Frontend.

Mentorship

As Senior Engineer, helping the team, unblocking colleagues and mentoring the junior/mid engineers is something I've done the last years and something I like honestly.

Bookieshunter

Bookieshunter.com is the website that I created while I was in college. Here I provide Sports Betting info to the customers in order to help them to win. I have learned a lot about development and boosting this business without any investment. Thanks to this site I could pay the college and other courses to improve my skills while mixing my main hobbie (sports) with my dream of having my own business.
