Profile Description

Experienced SQL Database Administrator with roughly 20 years of hands-on experience managing SQL Server environments—from legacy SQL Server 2000 to the latest versions of SQL. I am seeking a SQL Server DBA position where I can contribute my deep technical expertise to help your organization achieve optimal database performance, reliability, and security.
My strengths include advanced performance tuning, implementing robust security measures, designing effective maintenance plans, and developing automation strategies for proactive monitoring and reporting. I am passionate about delivering high-quality solutions that support business goals and drive innovation.

Top Skills

Software » Data Engineering » SQL

Experience: 10+ years

I use SQL scripting to build automated monitoring and reporting solutions that enhance SQL Server performance, availability, and security across production environments. One key project is the SQL Server Capacity and Forecast Report, which tracks database growth, disk utilization, and forecasts trends using custom scripts and visualizations for proactive capacity planning. I also created a lightweight, fully customizable SQL Server Objects Watcher to audit object-level changes such as table, view, and stored procedure modifications, as well as security changes. It features real-time monitoring, log file rollover, and prebuilt queries for easy retrieval. To ensure database uptime, I developed the Database Availability Watcher, which scans for OFFLINE, RESTORING, or SUSPECT states and sends 10-minute interval alerts with configurable suppression. For system health, the CPU and Memory Watcher tracks usage at both OS and SQL levels, identifies top-consuming processes, and triggers alerts every 5 minutes during threshold breaches. For performance issues, I built a Blockings Watcher that identifies long-running blocks, splitting reports into waiting processes and root blockers. I also implemented a Deadlock Watcher that provides real-time alerts with victim and conflict analysis for quicker resolution. From a security standpoint, I deployed the Suspicious Failed Login Watcher, which detects failed login attempts, sends immediate alerts, and logs activity for incident review. Additionally, I designed an Automated Inventory System to gather and centralize SQL Server instance and database configurations, aiding in audits, planning, and migrations. Lastly, I developed a Table I/O Monitor to analyze read/write performance per table, helping identify bottlenecks and optimize workload distribution. Each solution I developed supports real-time insight, faster root cause analysis, and operational excellence through custom-built, scalable SQL tools.

Other Skills

Software » Devops » Powershell

Experience: 1 - 2 years

I normallu use Powershell to do automate SQL process such as "Real-Time SQL Server Monitoring". I created that PowerShell-based monitoring tool to track real-time CPU, memory, database status, and server volume across SQL Server instances. The solution provides dual output: an on-screen dashboard with color-coded health indicators (Green, Yellow, Red, White) and detailed log files with timestamped metrics. Automatically flags and displays performance issues, enabling immediate awareness and action. Enhances system visibility, supports rapid troubleshooting, and ensures proactive SQL Server health monitoring.

Cloud Services » AWS » Stotage - S3

Experience: 2 - 5 years

I implemented an automated backup solution using AWS S3 to securely store copies of on-premise SQL Server production backups. This includes both full database backups and transaction log backups. The solution ensures offsite redundancy, enhances disaster recovery capabilities, and supports compliance with data retention policies by leveraging S3's durability and lifecycle management features.
