Software Engineer I @ Pathao

About

Hello! - I’m a Software Engineer at Pathao Ltd. and a graduate of East West University. I have over one year of experience in Android development. Currently, I’m working on Pathao’s Driver App using Kotlin/Java. - Also, I worked on Pathao Resto, a Flutter-based application used by restaurants to accept, update, or cancel orders based on availability, manage business hours and status, along with several other operational features. - Alongside my professional work, I’ve been active in competitive programming for more than 4 years. I’ve solved over 1500 problems across platforms like Codeforces, LeetCode, AtCoder, and HackerRank, and participated in 200+ online and 20+ onsite contests. - I’m comfortable working with data structures and algorithms, including graph theory (DFS, BFS, Dijkstra), dynamic programming (knapsack, LIS, LCS), number theory (sieve, prime factorization, modular arithmetic), and common structures like binary trees, linked lists, stacks, queues, and hashing. - During my undergraduate studies, I was also involved in research and published over 5 papers in international journals and conferences. I enjoy building real-world applications, solving challenging problems, and exploring innovative ideas through both development and research.
