DEV RANK

DEVELOPER RANKING & PROFILE AGGREGATOR PLATFORM

Dev Rank is an AI-powered developer profile aggregation and ranking platform. By integrating external APIs and web scraping routines, Dev Rank synthesizes developer activity across GitHub, LeetCode, and coding platforms into unified engineering rank scores, enabling peer comparison and talent discovery.

Key Performance Metrics & Impact

Profile Sources

GitHub & LeetCode

Aggregated coding metrics

Ranking Algorithm

Weighted Index

Balances commits, stars, & problem difficulty

Scraping Latency

< 1.2s

Fast asynchronous API fetch handlers

User Profiles

Community Scale

Ranking developer profiles seamlessly

Problem Statement

Recruiters and community leads lack a single objective metric to compare a developer's real-world code contributions alongside algorithmic problem-solving skills.

Engineering Solution

Constructed a profile parser and ranking engine with Next.js, Rapid API, and automated web scrapers that computes normalized rank metrics based on commit history, repository stars, and LeetCode problem difficulties.

Core Capabilities & System Features

Multi-Platform Profile Fetcher

Asynchronous data collectors gathering public metrics from GitHub repositories and LeetCode profile APIs.

Weighted Dev Rank Score

Custom scoring formula calculating overall developer tier by combining code frequency, star count, and solved problem difficulty.

Leaderboard & Search Matrix

Filterable community leaderboards enabling instant searching by stack, ranking tier, or institution.

Visual Badge Generator

Embeddable SVG cards displaying rank metrics for developer README profiles.
