Freelancer profile translated to English.
Back to original languageAbout José Ramón
SUMMARY: I have enough experience to design and implement any web or desktop application or to maintain an existing application.
I have recently programmed in Java and Kotlin, but I can use any other language, such as PHP, Javascript/Typescript, Golang, Python, etc.
20 years ago I installed my first Linux distribution, so I also have experience as a system administrator: Linux, bash or task automation.
----------------------------------------------------------------------------
I have been a web programmer for several years, specializing in Java technologies: Spring, Spring Boot, JPA/Hibernate, Maven, Eclipse, etc. I have also used Angular. I know other languages, such as Kotlin, Scala or C#.
Some experience deploying smart contracts on EVM networks (Ethereum, BSC, Polygon). Creation of ERC20 tokens and NFTs. Modification of smart contracts written in Solidity.
Before that, I was a programmer in C language (in Spain and England) and a Linux system administrator. I have used other languages, such as bash, Python, Perl, awk, SQL.
