EN I'm Javier Herrero, web developer in Bizkaia
Easy Web Devs is me: a developer from Barakaldo with experience in data projects for large companies, bringing that technical rigour to the websites of small and medium-sized businesses.
From building applications to building your website
I started in IT with a Higher Vocational Degree in Network Systems Administration and then in Multiplatform Application Development, at CF Somorrostro.
My first job as a programmer was at a software company in Bizkaia, where for over two years I built web and desktop applications with PHP, Python, Visual Basic and databases such as PostgreSQL, MySQL and SQL Server.
I then specialised in Big Data and since 2022 I have worked as a Big Data consultant at a multinational consultancy, now as a Senior, building data processes for large insurers and banks with Python, Spark, Databricks, Azure and Palantir.
With Easy Web Devs I bring that way of working to local businesses: well-built, fast websites, measured with data and designed to be found on Google. And with a direct relationship: you always talk to me, the person who designs and codes your website.
What your business gets
- 01
Direct contact
No middlemen or salespeople: you talk to the person building your website, from start to finish.
- 02
Experience in large projects
I bring to your website the same technical standards as in data projects for large companies.
- 03
Data-driven decisions
I come from the data world: I measure what happens on your website to improve it with numbers, not guesses.
- 04
Local and in three languages
I'm from Barakaldo and work in Spanish, Basque and English.
