Ideal Candidate Profile

We are looking for someone who can go beyond basic server administration.

The candidate should be able to understand and troubleshoot the complete technical flow:

Users → Website Frontend → Backend → API → Database → Web Server → Linux Server → Network

The candidate should be comfortable answering questions such as:

• How many users are currently accessing the website?
• How much traffic is the website receiving?
• Can the current server handle the traffic?
• Why is the website becoming slow?
• Which process is consuming CPU or RAM?
• Is the issue coming from the frontend, backend, database, network, or server?
• What happens when the number of users suddenly increases?
• Do we need additional server resources?
• Are there abnormal requests or unusual server activities?
• How can we improve system stability and performance?

Education

• Diploma or Bachelor's Degree in Computer Science, Information Technology, Information Systems, Network Engineering, Software Engineering, or a related field.

Working Style

• Hands-on and technically strong.
