Software Developer & Tech Lead

About me

I work as software developer focused on web technologies and I have a profile of both business and technology. I have worked in companies of different sizes and for clients of different nature. As a freelance I have collaborated with advertising agencies and developed my own projects

I am currently working full-time at Kimet Sport as Tech Lead and, because of my company's profile, I act as the "bridge" between business and development teams. I'm the responsible to plan and coordinate the developments of the company. So my effort is focused on helping the team deciding what to do and how to do it .

Also, I try to dedicate time and effort to improve my development skills and being up to date on web development trends. For this, I am developing pet project as proof of concept of an application with NestJS (Node.js + Typescript) and Docker.

I am passionate about technology, a tireless apprentice and a firm believer that helping others is the best way to improve.

Skills

These are some of the skills that I have been acquiring during my work experience, working both as an employee and freelance.

back-end

Last years I have been creating most of my projects with Symfony (PHP) and Java but now I'm developing with Javascript/Node.js. Mi prefered database is Postgresql but I've also got experience with MySQL and Oracle.

front-end

Because I'm not front-end developer, I usually start my projects with Bootstrap but I've also played with React and Vue (for testing purpose). For automating tasks, I've used Gulp, Bower and Webpack.

sysadmin

OSX, Linux and Windows user with skills to configure different technological stacks. I allways use Docker in my projects and I have experience in the use and configuration of cloud environments such as AWS and Digital Ocean.

design

I'm not a designer but I try to take care of the design of my works to the maximum, making them look good on any device. I defend myself well with Gimp and Photoshop.

management

I try to solve the gap between my company's business department and development teams, trying to prioritize based on the context, a good compression and a bit of strategy. I have experience interacting with different types of clients and I try to understand the needs of the market.

others

Currently I am very interested in the Cryptocurrencies and Blockchain world. I believe it's a technology that has come to stay and can change the world.

Experience

A brief history of my professional and experience career, both as an employee and developing own projects as a freelance.

Bachelor's degree and first job

I finish my bachelor's degree in computer science at Deusto University, I found my first job as developer and I was there working for a year. Why did I change? I'd loved web development and I was creating desktop applications.

2001 - 2002

IT Consultancy

With the rise of consulting and IT services companies, I went to work in one of them and I had the pleasure to work in different kind of projects. For the next 4 years I learned a lot, I met exceptional people and I get some good friends.

2002 - 2006

Management vs. Development

I changed my job and I started working for a small/medium enterprise and for a while I combined team management tasks and project development. Management tasks began to be my main work and I needed to invest most of my time with them.
I love to be part of teams who build products and deliver value to customers and I was wasting most of my time arround Words, eternal meetings... I needed to change it.

2006 - 2013

Get cracking!

Hoping to avoid weakening more my skills, I began developing web projects as a freelance collaborating some marketing agencies, created various enterprise intranets y designed some corporative webs.

2007 - 2013

First fail (probably not the last)

First attempt of entrepreneurship that went down. I began to introduce myself in the startup world.

2008

What is my way? (*)

Life changes me with a big surprise.
I try to help a friend of mine with his project and I create my own Roadmap: where I am, what I want to do, steps to follow...
* It's personal, I can not tell you everything on the first date. If you want more information, get in touch with me and we chat.

2010

Getting out from the comfort zone

After 7 years working on the same company, I decided to leave everything and started a new adventure. I didn't know how long we were going to survive but the challenge caught me and I bet for it.
We are still working hard so I think that something we did it well, didn't we? However we're growing up and we have a big challence and many possibilities for improvement. I believe we will attract great attention.

2013 - ¿?
