LeadForge

High-performance Rust CLI for concurrent lead generation from real-world data sources.

leadforge fetches and processes job listings (currently from Hacker News) using an async streaming pipeline with bounded concurrency, retry logic, and filtering — designed for building real lead generation workflows.

The tool is built for developers, freelancers, and founders who want to extract actionable opportunities from live data.

Features

Concurrent Data Fetching

Fetches job postings using bounded concurrency via async streams.

This allows hundreds of requests to be processed efficiently without overwhelming the system or the API.

---

Streaming Pipeline Architecture

Jobs are processed as a stream:

job IDs
↓
async fetch (concurrent)
↓
retry + timeout handling
↓
filtering (keyword)
↓
collected results

Benefits:

• efficient resource usage
• fast time-to-first-result
• scalable to large datasets

---

Retry & Resilience

Built-in retry logic with exponential backoff handles:

• network timeouts
• connection failures
• server errors (5xx)
• rate limiting (429)

This makes leadforge robust against unreliable APIs.

---

Keyword Filtering

Filter results directly in the pipeline:

• case-insensitive matching
• applied during streaming (no extra pass)

Example:

leadforge hacker-news --keyword rust

---

Structured Output (JSON)

Results are returned as structured JSON, making it easy to:

• pipe into other tools
• store results
• integrate with scripts or APIs

---

Example

Fetch the latest 5 Hacker News job postings:

leadforge hacker-news --limit 5

Example output:

[
  {
    "id": 47251163,
    "by": "yeldarb",
    "score": 1,
    "time": 1772646584,
    "title": "Roboflow (YC S20) Is Hiring a Security Engineer for AI Infra",
    "url": "https://roboflow.com/careers",
    "text": null
  }
]

---

Real-World Usage

leadforge can be used as a lead discovery engine:

Find Rust jobs

leadforge hacker-news --keyword rust --limit 20

---

Save results to a file

leadforge hacker-news --limit 50 > jobs.json

---

Pipe into other tools

leadforge hacker-news --keyword remote \
| jq '.[] | .title'

---

CLI Options

Option	Description
--limit <N>	Maximum number of job postings to return
--max-concurrency	Maximum number of concurrent HTTP requests
--max-retries	Retry attempts per request on transient failures
--timeout	Request timeout in seconds (per request)
--keyword	Filter results by keyword in job title

Example:

leadforge hacker-news \
  --limit 20 \
  --max-concurrency 50 \
  --max-retries 3 \
  --timeout 10 \
  --keyword rust

Documentation

Key components:

• run — core execution entry point
• LeadForgeCommand — command abstraction layer
• fetch_jobs — async pipeline for job ingestion
• LeadForgeError — structured error handling

---

Architecture

leadforge is structured as a clean layered system:

CLI (clap)
↓
Command conversion
↓
Execution (run)
↓
Async pipeline (streams + concurrency)
↓
HTTP client (reqwest)

This separation allows:

• easy extension to new data sources
• clean testing
• reusable core logic

---

Performance

The tool is optimized for:

• high concurrency
• low overhead per request
• minimal blocking

Performance depends on:

• network latency
• API responsiveness
• concurrency settings

---

Installation

Build from Source

git clone https://github.com/writeonlycode/leadforge
cd leadforge
cargo build --release

Binary:

target/release/leadforge

---

Why Rust?

Rust allows leadforge to combine:

• high concurrency without threads explosion
• memory safety
• predictable performance
• zero-cost abstractions

This makes it ideal for data ingestion pipelines and lead generation tools.
