Presentation
I’m a mainframe developer working on enterprise COBOL systems in banking, including large-scale EGL-to-COBOL migration projects in an Agile/SAFe team. I offer three kinds of services:
Mainframe / COBOL
– Debugging and fixing COBOL programs (abends, wrong output, data issues)
– Reading, documenting and explaining legacy code
– JCL job setup and troubleshooting
– DB2 queries and embedded SQL in COBOL
– Help with code migration and modernization
Websites
– Modern, fast, mobile-friendly websites for small businesses, clubs, events and personal brands
– Design, build, deployment and hosting setup
– Contact forms, galleries, multilingual pages
– Updates and fixes to existing sites
Technical support & helpdesk
– Troubleshooting hardware, software, network and connectivity issues
– Microsoft Office and Microsoft 365 setup and support
– Email configuration and problems (Outlook, Gmail, domain email)
– VPN setup and remote access issues
– Account, password and access-related problems
– PC setup, cleanup and performance fixes, remotely or on-site in Varna
I communicate clearly, explain things without jargon, and make sure the solution actually works for you. Send me a message describing what you need, and I’ll reply with a clear plan and estimate.
