Merging two analytics stacks
Led the post-acquisition technical integration of Clicktale into Contentsquare, consolidating a 5 TB/day session-replay pipeline into the combined platform with zero customer-facing downtime or data loss.

When Contentsquare acquired Clicktale, the two companies had overlapping products built on different stacks. My job was to make them one platform without the customers of either ever feeling it.
The integration
I led the post-acquisition technical integration as Engineering Manager for Platform and Infrastructure. The centerpiece was a 5 TB/day session-replay pipeline that had to move from Clicktale's stack into the combined Contentsquare platform.
- 5 TB/day, zero downtime. We consolidated the pipeline into the combined stack with zero customer-facing downtime and no data loss, cutting over in stages and running both paths in parallel until each slice was proven before we retired the old one.
- Legacy engines, modern requirements. I refactored the legacy rendering engines to meet multi-tenant, enterprise-scale requirements while preserving the core IP that made the product valuable in the first place.
- Decommission, do not just leave it running. We shut down the redundant on-premises infrastructure once traffic was fully migrated, which is the half of every migration teams quietly skip and pay for later.
Why it mattered
M&A integrations are where platforms go to die: two roadmaps, two on-call rotations, two ways of doing everything, and a clock. We came out of it with one stack, a stronger reliability and performance posture across the combined platform, and a foundation the next wave of products could actually build on. Two stacks became one, and no customer felt the seam.
