a compact developer library for technologies, dsa notes, problem explanations, roadmaps, cheatsheets, and search. built for fast lookup while learning, building, and revising.
choose the route by intent: learn a technology, study DSA, solve a problem, follow a roadmap, revise a command, or search everything.
technologies
runtime notes for frontend, backend, databases, deployment, tooling, and the practical decisions that come up twice.
core index
dsa
your own concept notes, pattern recognition guides, dry runs, complexity notes, and topic maps.
notes
problems
leetcode and codechef explanations with brute force, optimized approaches, complexity, and edge-case notes.
solutions
roadmaps
sequenced learning paths that connect topics, notes, projects, and problem sets into one route.
paths
cheatsheets
fast command, syntax, config, and API references for workflows that should not need another search.
quick refs
search
global lookup for titles, summaries, tags, difficulty, content type, and problem platform filters.
lookup
from rough learning to reusable reference
the homepage is shaped around the final public site: clean docs navigation, searchable indexes, related content, tags, difficulty, and code-heavy pages that are easy to scan.
