Learning resources in Bangla and for Bangladeshi learners: system-design courses, interview archives, algorithm visualizers, competitive-programming references and student resource platforms. This is the section where community effort dwarfs institutional output — most of these are maintained by individuals giving back, often alumni writing the guide they wish had existed when they started. Everything is free to access; course-locking and paywalls would disqualify an entry here.
