MergedCode software engineering workspace. One software engineering workspace — Learn (DSA, Core CS, system design, AI, languages), News, Kanban, Calendar, and Canvas.

MergedCode is a single place to practice data structures and algorithms, read Core CS (DBMS, operating systems, computer networks, OOPS), work through system design LLD and HLD, follow AI and language tracks, scan curated tech news. The workspace also includes Kanban, Calendar, and Canvas for planning and sketching while you learn. Public catalogs and the news feed are available without a paid account on MergedCode; OpenAPI lives at /openapi.json and the agent index at /llms.txt.

Why MergedCode

Six tabs. One workspace.

Learning and building in tech is usually spread across a problem site, notes, videos, a to-do list and a whiteboard. Here each of those has one home — and they know about each other.

Before

6 tabs

  • A problem site
  • A progress spreadsheet
  • PDF notes for DBMS and OS
  • System design videos

  • A separate whiteboard tool

With MergedCode

1 tab

  • 641 DSA problems that remember what you solved
  • Core CS lessons you can finish in one sitting
  • LLD and HLD problems with real diagrams
  • 9 roadmaps that put every topic in order
  • Kanban and Calendar beside your practice
  • Canvas that keeps every diagram
