About Lorena

I am a software and web developer with several years of experience in industrial and application environments, working on both back-end projects and business interfaces. I support my clients from the analysis of needs to the production phase, offering robust, maintainable, and documented solutions.

I primarily work on back-end development projects (PHP/Symfony, C#, Python), automation, internal tooling, automated testing, and process optimization. I am accustomed to working in demanding contexts, with quality, performance, and security constraints, and I integrate easily into existing teams.

My approach is pragmatic and results-oriented: a thorough understanding of business issues, clear communication, clean and scalable code. I can be involved in one-off tasks (feature development, refactoring, scripting, technical audits) as well as longer projects requiring monitoring and a global vision.
