About Debashish
Hi, I’m Debashish, a Mainframe Developer & Consultant with 11+ years of experience in Banking and Insurance domains.
I specialize in COBOL, JCL, Assembler, VSAM, and Mainframe debugging. Over the years, I’ve trained and mentored freshers and junior developers in IT companies, helping them understand legacy systems, write efficient code, and prepare for interviews.
What I Teach:
COBOL programming (beginner to advanced)
JCL – job control, utilities, optimization
Assembler basics for mainframe developers
Debugging with File-AID, Abend-Aid, XPEDITER
Real-time case studies from Banking & Insurance systems
Mainframe interview preparation (mock interviews + Q&A)
My Teaching Style:
Hands-on, practical approach – learn by solving real project problems
Break down complex code into simple explanations
Provide notes, flowcharts, and exercises for practice
Flexible pace depending on your background
Who Can Benefit:
Fresh graduates preparing for mainframe roles in TCS, Infosys, Wipro, NTT, etc.
Junior developers who want to strengthen debugging & problem-solving
Professionals moving into mainframe support or modernization projects
I believe anyone can learn mainframes with the right guidance. Book a session with me and let’s get started

Basically, I prefer teaching one student at a time which gives me more time to interact and understand the problems faced by him/her. My approach is more on practical application of the topic rather than just focussing on theoretical understanding.
