Hire the Best Java Developers
in Colombia

Hey! Robin here. I help business owners integrate AI technologies into their workflows. Check out my 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝗰𝗮𝘁𝗮𝗹𝗼𝗴 for budget-friendly, self-hosted AI solutions fine-tuned to your specific needs. ● 𝗔𝗯𝗼𝘂𝘁 𝗠𝗲 Hi, I'm Robin — a Mechatronic Engineer who was drawn to the “dark side” of software development early in my career. Always striving to stay up to date, I've gained real-world experience with most of today’s popular software development technologies (full list below). I take time to understand both the business goals and the technical requirements of your project before writing a single line of code. This ensures you're paying for solutions that truly work, pushing your project in the right direction with every sprint. I'm not the kind of freelancer who just completes tasks for the sake of getting paid. I've been working as a software developer since 2006 and on Upwork (formerly oDesk) since 2012. Freelance projects here put food on my table, so you can expect full dedication. I only take on one job at a time and always aim to respond quickly. I'm online during standard office hours, Monday through Saturday, and my time zone is GMT-5 (same as New York) year-round. ● 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝗶𝗲𝘀 Ongoing (Back-end Developer) Vagrant, RESTful 2018–2020 (Java Web Development) Spring Boot, JSF, PrimeFaces, JAXB, JAX-RS, SQL Server 2008 2017–2018 (JavaScript Mobile) Node.js, Express, React Native, iOS, Xcode, Blockchain 2013–2017 (PHP Web Developer) PHP 5, MySQL, Laravel, Lumen, AWS EC2, AWS RDS, AWS CodePipeline, AWS Elastic Beanstalk, Cloud9 IDE, GitHub, Bitbucket 2012–2014 (Java Desktop and Web) J2SE, Struts, Derby DB, MySQL, JDBC, Hibernate, Jasper Reports, NetBeans, Tomcat 2009–2012 (.NET Web Developer) Visual Studio 2008–2010, ASPX, ADO.NET, Silverlight, MVC (.NET), WCF, ADO.NET Data Services, MS SQL Server, Oracle, SVN, Scrum 2007–2009 (Windows Desktop Software) Borland Delphi 6, MS SQL Server 2000, Oracle, Firebird, JEDI Version Control System, PMP/Waterfall methodologies 2006–2007 (Hardware–Software Integration) C/C++, Borland Builder 5 & 6, OLE DB, ADO components

Java sits at the center of the platforms I build. Spring Boot runs the backend services and APIs, handling business logic, data access, and the core behavior of the system. Many of these platforms pair a Spring Boot backend with Angular on the frontend, forming structured web applications such as internal dashboards, operational platforms, and SaaS systems used by teams every day. Angular provides the application interface while the Java backend manages services, data, and integrations behind the scenes. Python also comes into play when automation or data workflows are needed. Small services and scripts written in Python handle background tasks, integrations, and operational processes that support the main platform. Java and Spring Boot handle the backend services, Angular runs the platform interface, and Python supports automation and background tasks.

I’m a developer experienced building java, spring boot, data base, mobile application application businesses.
