I’ve been experimenting with AI personas and built a digital twin focused on:

• System Design interviews
• Distributed systems
• Scalability discussions
• Backend architecture
• Engineering leadership
• FAANG-style interview prep

You can chat with it here:

Some things you can try:

• “Design YouTube at scale”
• “How would you architect Uber?”
• “When should I use Kafka vs RabbitMQ?”
• “How do senior engineers think during interviews?”
• Or even ask personal questions and see how “I” respond 😄

The interesting part is that it doesn’t just answer questions — it responds in a way that reflects how I think and communicate.

Would love honest feedback from this community:

• Does it feel useful?
• Does the reasoning feel senior-level?
• Where does it completely fail?

Curious whether AI mentors/twins like this become normal in the next few years.
