Hi! I'm Ahnaf Shahriar Asif

NHSPC nationals Top-10; BDOI 6th (2019) and 5th (2020)—earning bronze, then silver. I study CSE & Mathematics at BRAC University and compete in ICPC/IUPC.

I make algorithms approachable—idea first, code next, optimize last. I’m patient with bugs and relentless about clarity.

  • Algorithms: two-pointers, binary search, greedy, DP patterns, graphs
  • Math for CP: prefix sums, combinatorics, bit tricks, modular arithmetic
  • Debugging & complexity: edge cases, asymptotics, memory
  • Ladders, timed contests & editorial-style walkthroughs
