Preparing for software engineering interviews? I'll help you crack system design and DSA rounds with 1-on-1 mentoring.


5+ years as a backend engineer with strong foundations in DSA and system design. I know what interviewers look for and where candidates fail.


SYSTEM DESIGN:

- Step-by-step approach to any design question

- Real systems: URL shortener, chat app, rate limiter, news feed

- Database selection, caching, load balancing, tradeoffs

- Communicating your design clearly to interviewers


DSA:

- Patterns: sliding window, two pointers, BFS/DFS, DP, greedy

- Recognizing WHICH pattern to apply

- Writing clean, optimal code under pressure

- Explaining your thought process out loud


BACKEND:

- Python, Django, FastAPI best practices

- API design, database design, authentication

- Building production-ready projects for your resume


HOW IT WORKS:


1. Tell me your target companies and level

2. I assess your strengths and gaps

3. We create a focused study plan

4. Weekly sessions via Zoom/Google Meet

Not a generic course. Every session is tailored to YOUR level, YOUR gaps, and YOUR targets.
