LinkedIn Connection Tracker

REST API & OAuth 2.0 application tracking connection lifecycle states

Project Overview

Developed a specialized tracking tool using Python, FastAPI, and PostgreSQL to manage LinkedIn network expansion. Authenticated via OAuth 2.0, the system tracks connection invite states, maintains historical records in PostgreSQL, and generates analytical dashboard statistics to measure network response rates.

The Problem

Tracking outgoing networking outreach and connection status across industry contacts was difficult without automated state tracking.

The Solution & Architecture

Built a secure FastAPI backend with OAuth 2.0 integration that persists connection request state changes to PostgreSQL and provides statistical summaries via REST endpoints.

System Data Flow:

LinkedIn OAuth 2.0 API→FastAPI Backend→State Manager→PostgreSQL Database→Dashboard Statistics

Key Engineering Highlights

OAuth 2.0 authentication flow

LinkedIn API integration for network data

Connection lifecycle state tracking (Pending, Accepted, Rejected, Withdrawn)

Structured persistence in PostgreSQL database

Dashboard statistics for outreach metrics

API unit and integration testing
