Back to original languageAbout Marco
Hello, I'm Marco Ruiz, a SysAdmin and Full-Stack Developer with real experience in corporate environments and critical internal application development.
I currently work in a company where I design, maintain, and evolve daily tools for different departments, integrated with real systems (ERP, databases, internal workflows). My profile combines infrastructure, development, and automation, allowing me to understand IT problems globally and solve them efficiently.
In my day-to-day:
- Designed and developed internal web applications for data management, dates, processes, and operational control
- Automated manual processes, reducing errors and saving real time for non-technical teams
- Worked with relational databases (Oracle, MySQL), access control, auditing, and history
- Optimized performance, cache, and backend flows in production environments
- Deployed and maintained applications on servers with Apache
As a Full-Stack developer, I don't limit myself to "programming screens": I think about usability, stability, maintenance, and scalability. I get involved as if I were part of the client's team and prioritize clear, robust, and business-aligned solutions.
Usual Stack:
- Backend: Python (Flask), APIs, business logic
- Frontend: HTML5, CSS3, JavaScript, jQuery, Bootstrap
- Databases: Oracle, MySQL
- Infrastructure: Linux, Apache, deployment, and maintenance
What sets me apart:
- Practical SysAdmin mindset applied to development
- Clear and honest communication (no unrealistic promises)
- Projects that work and can be maintained over time
If you are looking for someone who understands your infrastructure, programs with judgment, and delivers truly usable solutions, I will be happy to talk with you.
