I'm Nasir Uddin Khan, a freelance IT professional based in Dhaka with 18+ Years of hands-on experience. My core specialization is IT Infrastructure architecture and ERP System Design, powered by enterprise databases including Oracle 26ai, SQL Server & MySQL.
I deliver stable, secure, scalable, and business-aligned technology — from RAC + Data Guard production clusters to AI-powered ERP assistants. The full stack covers Oracle DBA, WebLogic middleware, web hosting, full-stack development, SEO, and modern ERP + AI integration.
I work with both Bangladesh-based clients and international organizations — software firms, banks, agriculture, pharma, and logistics. Every engagement starts with understanding your real business pain, not just the technical symptoms.

Experience in full-stack web support, hosting management, technical SEO, and digital platform maintenance — beyond just databases.
Focused on clear communication, audit-ready documentation, and long-term supportability — so the next person can pick up where I left off.
