Aspiring PhD student interested in distributed systems and data-intensive computing. I enjoy building reliable, scalable systems and understanding how storage, replication, and consistency mechanisms shape real-world performance. Always learning, experimenting, and writing about systems.

Competitions & Project Write-ups

This section includes write-ups for competitions, benchmarks, and projects related to distributed systems and data-intensive applications.

I use these write-ups to reflect on:

  • the problem setting and constraints,
  • system design and architecture choices, and

  • what went well, and what I would do differently next time.
