The man behind it

Tier 3 college.10+ remote jobs. AI Architect.

Hey! I'm Prince Singh. I came from a Tier 3 college with no senior, no network, no roadmap. Just raw hunger to figure it out.

I cracked 10+ remote SDE jobs not because I was the smartest in the room, but because I built the right systems, followed the right patterns, and never stopped shipping.

Today I build production AI systems - LLMs, RAG pipelines, multi-agent architectures - at a Founding Engineer level. And I teach everything I know on Preparation Street.

1,00,000+ engineers are already on this journey. Come build with us.

Prince is a wonderful person. He listened to all my requirements very carefully without any interrupt. He then suggested a career option which was most relevant to my current situation, closest to reality. He is one gem and he is the best if you want either career or technical guidance

Sourav Upadhyay

The mentorship session really helped me gain clarity on my path. I not only got answers to my doubts but also understood how to properly use available resources and start working on meaningful projects in Python and AI/ML. What I appreciated the most was how patiently the mentor guided me through the parts where I used to get stuck while following tutorials. It was a very motivating and direction-setting experience for me. Thank you for this amazing mentorship Prince Bhaiya ❤️🙏🙇

Great Session, It looked like he wanted to help me out and not just end the session after 30 mins. If you want a clear Idea on How to improve in DSA or How to become a better SWE then I highly recommend Prince.

Prince is an exceptional mentor and a highly skilled engineer. His deep clarity across various fields sets him apart, and he has cleared all my questions. He not only addressed all my doubts but also provided insightful suggestions and practical solutions that exceeded my expectations. His guidance has been truly valuable. If you’re looking for a knowledgeable mentor who offers real, hands-on learning experiences, I highly recommend booking a session with Prince on Topmate. You won’t be disappointed!

FAQ

Questions,answered straight.

Still unsure where to start? Pick a goal at the top of the page and follow the route.

Start with the free sheet

Yes. All 150 problems - statements, examples and test cases - are free forever. Log in to track your progress. Solutions for the first section are free too; the rest unlock with TRISHUL or FTM.
Instead of a flat problem list, it groups problems by pattern - sliding window, two pointers, BFS/DFS, DP and more - with the recognition clue for each, so you learn to spot the problem type, not memorise solutions.
Four premium paths - AI Architect, Everything About DSA, Algorithm Accelerator and System Design - with progress tracking, XP and ranks, and a verifiable certificate for every path you finish. Some plans also include 1:1 sessions.
You pick one of eight focused topics - AI engineering, DSA, remote jobs, resume, mock interviews and more. It's 45 minutes 1:1 with Prince, booked right here, with a Google Meet link. You leave with a specific plan you can act on the same day.
Full-Time Personalized Mentorship runs 3, 6 or 12 months: a weekly sprint plan, a Saturday review with a mock interview, and Sunday re-planning - until you're placed. Not sure yet? Book a single trial session first.
It has 21 phases and 63 hands-on projects, from Next.js SaaS fundamentals to production multi-LLM systems. It's self-paced; in FTM it's sequenced into weekly sprints for you.
No - each account is for one person. Progress, XP and certificates are issued in that learner's name.
