Overview
Project overview
ProxyLister collects free proxy listings from multiple sources, normalizes them, and runs checks for geography, reachability, and behavior across protocols. Results are exposed through an API with sorting and filtering so clients can query what they need. A WordPress plugin makes the same proxy inventory embeddable on any WordPress site.
Role
Role and responsibilities
The work covered product thinking, engineering decisions, and practical delivery.
- Backend architecture
- Django services and API design
- Parser and ingestion pipelines
- Health and geo verification workflows
- Filtering and pagination for consumers
- WordPress plugin packaging
Challenge
The challenge
Free proxy lists change constantly and vary in quality. The system had to merge noisy sources, discard dead endpoints quickly, and still present trustworthy metadata without overwhelming API consumers.
Approach
The approach
- 01Built ingestion jobs that pull from diverse list formats and normalize IP, port, protocol, and anonymity fields.
- 02Added verification passes for connectivity and protocol behavior alongside geo and ISP signals.
- 03Designed REST endpoints with filters for protocol, country, anonymity, latency, and related facets.
- 04Shipped a public-facing directory at proxylister.com to demonstrate the dataset.
- 05Delivered a WordPress plugin so publishers can surface proxy tables without custom backend work.
Outcome
What it delivered
- A live proxy directory and API-backed workflow demonstrated at proxylister.com.
- Repeatable validation pipeline instead of one-off manual lists.
- Flexible querying for integrators plus a turnkey WordPress embedding option.
