Complex Multi-Platform Migration Landscape
Driving Enterprise-Scale MarTech Transformation and Platform Modernisation
Our customer undertook a large-scale modernisation of their marketing technology (MarTech) ecosystem, encompassing three critical platform migrations across campaign management (Salesforce to MoEngage), behavioural analytics (Google Analytics to Amplitude), and mobile attribution (Adjust to AppsFlyer).
The programme aimed to optimise operational costs and drive efficiency gains while enhancing the overall user experience. However, delivery was impacted by stringent third-party vendor constraints, including limited API payload capacities and aggressive rate restrictions when processing high volumes of user and event data within tight peak traffic windows. Additionally, the migration demanded stringent compliance adherence, requiring robust controls for the secure handling and tokenisation of personally identifiable information (PII) across all data flows.
Architecture Design and Platform Engineering Expertise
Delivering Scalable Solutions to Enable High-Volume Data Integration
TEKsystems deployed specialised software engineering expertise to accelerate the migration of the customer's MarTech ecosystem, resolving complex integration challenges across multiple platforms. Our team also designed and implemented a scalable, high-volume data ingestion framework that enabled reliable event processing, customer segmentation and data activation at scale.
- Stack Migration: Supported the three-platform MarTech transition across MoEngage, Amplitude, and AppsFlyer, resolving critical blockers.
- Vendor Architecture: Designed workaround integration patterns, including vendor‑direct S3 access and dynamic SFTP routing, to operate within payload and rate-limit constraints.
- Event Pipeline: Implemented a high‑volume recent event syncing pipeline supporting 15+ event types to feed customer actions into the MarTech stack.
- Segment Engine: Built a highly concurrent user segment syncing service using PostgreSQL advisory locks to prevent duplication while mapping and uploading cohorts to platforms such as Amplitude.
