ADS Solutions: Automated E-commerce Bridge
Role: Lead Developer | Duration: 2024
ADS Solutions is a suite of sophisticated software tools designed to bridge the gap between Amazon and eBay marketplaces. The system leverages Amazon Prime's 5% cash back benefit while providing international customers with a simplified purchasing experience, eliminating the need for complex customs paperwork.
The solution comprises multiple integrated components:
- Order Management: Automated processing of eBay orders with direct fulfillment through Amazon
- Price Optimization: Dynamic pricing system accounting for cash back benefits and market conditions
- International Bridge: Streamlined process for international customers to purchase through domestic channels
- Automation Suite: Complete end-to-end automation of order processing and fulfillment
Automation Implementation Notice: This project utilizes sophisticated proxy rotation and browser fingerprinting techniques to mitigate bot detection systems. While these methods were implemented for educational purposes and proof of concept, users should be aware that:
- Automated interactions with e-commerce platforms may violate terms of service
- Proxy rotation and browser fingerprinting are used to demonstrate technical capabilities
- Implementation details are shared for educational purposes only
- Users should review and comply with platform policies before deployment
Bot Detection Mitigation Techniques
- Proxy Rotation: Dynamic IP switching using residential proxies
- Browser Fingerprinting: Randomized device signatures and user agents
- Request Patterns: Human-like timing and behavior patterns
- Session Management: Cookie and session handling for authenticity

Technical Challenges & Solutions
Rate Limiting
Managing API rate limits across multiple marketplaces while maintaining system responsiveness.
Solution:
class RateLimiter:
def __init__(self, max_requests, time_window):
self.max_requests = max_requests
self.time_window = time_window
self.requests = []
self._lock = asyncio.Lock()
async def acquire(self):
async with self._lock:
now = time.time()
# Remove expired timestamps
self.requests = [req for req in self.requests
if now - req < self.time_window]
if len(self.requests) >= self.max_requests:
sleep_time = self.requests[0] + self.time_window - now
if sleep_time > 0:
await asyncio.sleep(sleep_time)
self.requests.append(now)
Data Synchronization
Maintaining consistency between marketplace inventories and order status.
Solution:
class InventorySync:
def __init__(self):
self.cache = Cache()
self.lock_manager = LockManager()
async def update_inventory(self, product_id, quantity):
async with self.lock_manager.acquire(f"inventory:{product_id}"):
try:
# Update local cache
await self.cache.set(f"inventory:{product_id}", quantity)
# Sync with marketplaces
await asyncio.gather(
self.update_amazon_inventory(product_id, quantity),
self.update_ebay_inventory(product_id, quantity)
)
except Exception as e:
# Rollback on failure
await self.rollback_inventory_update(product_id)
