I'm Nasir โ an Oracle DBA and ERP + AI integration specialist. I build reliable, secure database systems and AI assistants that let your team ask questions in plain English and get answers from your real business data in seconds, not days. Serving Bangladesh and clients worldwide since 2007.
Each solution mapped to the business problem it removes โ from uptime to plain-English answers on your own data.
A single database server is a single point of failure โ a hardware fault, maintenance window, or site outage can take business-critical systems offline for hours.
What I doConfigure Oracle RAC for server-level failover and Oracle Data Guard for a synchronized standby โ covering both local high availability and disaster recovery.
The database keeps running through a server failure with no outage, and can fail over to a standby site if the primary is lost โ protecting uptime and data.
When the application runs on a single WebLogic server, heavy traffic slows it down and any failure takes the whole application offline.
What I doConfigure WebLogic clusters with load balancing and failover across multiple managed servers.
Load is spread for better performance under pressure, and if one server fails the rest keep the application available โ no single point of failure.
Getting information out of an ERP usually means waiting on IT for custom reports or running slow manual queries, so decisions wait for data.
What I doIntegrate AI with the ERP using Oracle AI Database 26ai in-database vector search, so staff can ask questions in plain language and the data never leaves the database.
Teams get answers from their own business data in seconds instead of waiting for reports โ securely, inside the company's database.
