Looking for stability, performance, and total security for your data?
I help technology companies build database systems that don't fail, scale seamlessly, and are protected under banking standards.
With 15 years of experience in critical environments (Banking and Pharmaceuticals), I understand that the database is the heart of your business. My job is to ensure that heart is fast and never stops.
How can I add value to your team?
My differential value is my hybrid profile: I am an expert DBA, Developer, and Systems Administrator.
Performance without bottlenecks: I optimize the engine and queries to make your application fly.
24/7 Availability: I design and implement high-availability architectures so your service continues to run no matter what.
What projects do I usually manage?
- Health Audits: I analyze your database and provide you with an action plan to improve speed and security.
- Migrations and Upgrades: I move your data to modern versions with minimal service impact.
- Disaster Recovery Plans: I configure backups and external replications so you never lose a single record.
- Automation: In addition to SQL management, I work with scripts in PowerShell, Python, or Bash to ensure heavy tasks are done automatically and without human error.
International Experience and Languages
I have worked in Spain, the United Kingdom, and Malta. I integrate perfectly into teams working in English or Spanish, providing clear, technical, and professional communication.
My commitment to quality
I am extremely organized with documentation and configuration and code standards. I provide details of the process to understand the reason for each step taken.
My priority:For you to focus on selling and for me to ensure your data is always available and secure.
