Case Study: National Classifieds Platform Development for List

Client

List is the most popular online classifieds marketplace in Armenia. People across the country use it to buy, sell, and find services, so the platform has to run fast and reliably even under loads of millions of visits.

Challenges

For a national marketplace, running without failures even at peak hours is critical. The client needed a platform that handles high loads, stays simple for any user, generates revenue from paid listings, and provides accurate behavior analytics.

The audience: private users, stores and businesses with commercial offers, service companies in repair, delivery, and construction, and job seekers.

Stability under load: fast, failure-free performance at peak hours.
Convenient search: categories, subcategories, parameter search, and regional filtering.
Monetization: premium listings, subscriptions, and bumping listings to the top.
Mobile access: a web app with offline viewing of listings.
Content quality: moderation for listing safety and quality.

Solution

Architecture built for load. We designed the marketplace structure, category database, and search with high traffic in mind. The interface was kept simple, with an emphasis on quick access and listing readability.
Platform core. We implemented registration, ad posting, notifications, internal chats between users, and a content moderation system.
Paid services via Stripe. We implemented payments for premium packages and featured top placement of listings via the Stripe API.
Speed at the infrastructure level. Cloudflare caching and the HTTP/3 protocol minimize latency, while the PWA provides mobile access with push notifications and offline viewing. GA4, Hotjar, and Cloudflare Browser Insights show real-world speed and user behavior.
Scalability testing. System stability was load-tested on AWS.

Results

Over 1.5 million visits per day with no drop in speed.
48% faster average page load thanks to Cloudflare and HTTP/3.
+33% premium listing conversion after the Stripe integration.
Over 60% of users visit from the mobile version, and listings are also available offline.
More accurate analytics of behavior and UX metrics thanks to GA4, Hotjar, and Cloudflare Insights.
