Mobile Platform Audit Before US Launch
The review was commissioned to determine whether a consumer mobile platform could carry its planned US launch load, and which changes belonged before launch.
Engagement facts
| Fact | Detail |
|---|---|
| Client | Consumer mobile platform, regulated entertainment, pre-launch in the US market |
| Counterpart | Product engineering team of five, implementing alongside the review |
| Period | 2024 |
| Format | Five weeks, part-time and remote, embedded with the delivery team |
| Stack | Managed cloud, TypeScript, PostgreSQL, cross-platform mobile |
| Fee | CAD $20,930 |
Review lenses applied
Performance, reliability, delivery velocity, cost at scale, and access posture were reviewed against the planned launch rather than development traffic.
Measured outcome
85% reduction in network traffic to the mobile client and 20x latency reduction on the highest-volume API paths, both against the pre-engagement baseline.
How the review ran
- Production-like paths, traffic shape, environments, and costs were baselined.
- Blobb worked with the five-person product engineering team while changes were implemented.
- Each result was measured before the next change began, then the remaining launch risks were read out.
Findings register
| ID | Finding | Classification |
|---|---|---|
| F-01 | Transport payloads were sent without effective compression. A contained change reduced mobile network traffic by 85% against baseline. | Immediate |
| F-02 | Highest-volume API paths repeated expensive data work. Targeted query and path changes reduced latency by 20 times against baseline. | Immediate |
| F-03 | Heavy work ran synchronously inside user requests. Extraction into asynchronous processing reduced request contention. | Structural |
| F-04 | One shared environment made release validation and recovery depend on the same state. Environment separation was sequenced. | Structural |
| F-05 | The cost curve at launch scale was driven by work per request, not only request volume. Thresholds and measures were established. | Watch |
What was left with the client
A performance baseline, implemented changes, findings register, environment plan, cost curve, launch thresholds, and a sequenced action list.
