AdTech SaaS Platform (VAST/VPAID)
High-throughput ad serving with reliable event ingestion
Overview
The Ads Platform is a backend system that helps digital products serve advertisements across different types of media placements, including banners and video ads.
The platform connects publishers with multiple ad auction providers. When a request comes in, the system selects the most relevant auction source, requests available bids, chooses the best bid, and returns the final ad creative in VAST or VPAID format. The creative is then parsed and displayed by the client platform based on the supported ad type and placement.
The system handles high request volume, different auction responses, VAST/VPAID XML variations, wrapper logic, provider-specific formats, and failure cases while keeping ad delivery fast and reliable.
My Contribution
- Improved backend logic related to VAST/VPAID parsing, XML validation, and wrapper handling.
- Worked on infrastructure and backend flows responsible for selecting the best bid from multiple auction providers.
- Added better monitoring, logging, retry logic, and error handling to improve production visibility and platform reliability.
- Helped stabilize ad delivery by handling provider-specific response formats, edge cases, and broken creative payloads more predictably.
