An advertising exchange that combines several popular ad formats from regular banners to clickunder's. The project brings together those who want to sell ad

An NDA client wanted one exchange to monetize traffic across banners, teasers, pop-under and clickunder for professional arbitrage teams. The product was not a classified board but an ecosystem where dozens of targeting dimensions, bids and offer quality run in real time without losing visitors to latency.
The smart auction had to rank ads not only by CPC but by placement fit and user behavior — otherwise an expensive irrelevant offer displaces a better long-term earner. The platform also had to record transit clicks and affiliate postbacks reliably.
We reused prior exchange experience but added unique traffic redistribution: an unsold click rolls to the next monetization tier through CPA networks with sub-account chains — details stay private under NDA.
Microservices scale out horizontally; the auction sits outside the monolith and message queues absorb RPS spikes. Raw clicks aggregate in memory before persistence so the RDBMS is not flooded with millions of inserts per second.
The SPA cabinet renders large reports without reloads; the admin panel governs offers, format ratings and advertisers. Partner integrations unify callbacks — exchange marketers shift flows without publisher deploys.
Delivery moved from anti-fraud core and tracking to finance and UI: we studied arbitrage specifics, embedded twenty-plus behavioral checks, ran load scenarios, then opened the full format set for pilot publishers and affiliate networks on AdsTime.org.


The exchange handles hundreds of thousands of ad requests per minute; the eCPM auction raised publisher yield while advertisers saw cleaner traffic with fewer accidental clicks, better geo/device fit, no static feeds dominating placements and clearer disputed-click logs.
Multi-step redirect and the CPA gateway cut idle impressions and monetize leftover traffic faster for the publisher pool. End-to-end stats show the path from impression to partner conversion net of fees, holds, sub-account chains and net webmaster income.
For ESK the build deepened affiliate and high-load expertise — we reuse arbitrage handling, postback gateway and realtime aggregation in later NDA ad-tech and CPA work, from auction core and anti-fraud to exchange finance modules.
