DEV RANK

AI-POWERED DEVELOPER RANKING & BENCHMARKING 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 and LeetCode into unified engineering rank scores using LLM scoring heuristics, powering automated talent discovery.

Key Performance Metrics & Impact

Profile Sources
GitHub & LeetCode

Aggregated coding & algorithmic metrics

LLM Heuristics
Codebase Analysis

Evaluates architectural structure & algorithmic quality

Scraping Latency
< 1.2s

Secure, OTP-verified web scrapers

Recruiter Discovery
Automated

Connecting top verified engineering talent

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, Express, MongoDB, and LLMs that computes normalized rank metrics based on commit history, repository stars, codebase structure, and LeetCode problem difficulty.

Core Capabilities & System Features

01

Multi-Platform Profile Fetcher

Secure web scraping engine gathering public metrics from GitHub repositories and LeetCode profile APIs.

02

LLM Scoring Heuristics

AI-powered scoring formula evaluating codebase design patterns, documentation quality, and problem-solving mastery.

03

Recruiter Discovery Hub

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

04

Visual Badge Generator

Embeddable SVG cards displaying rank metrics for developer README profiles.
