Our History & Founding Background
Flow Vertex Core was founded in Bangkok in 2021 by a group of senior mobile systems engineers and backend telemetry architects. During our tenure leading mobile infrastructure for cross-border financial and logistics applications in Southeast Asia, we observed a critical, recurring measurement blind spot: engineering and product growth teams were making major architectural and marketing decisions based on flawed push notification metrics.
Standard third-party SDKs and gateway consoles were reporting HTTP 200 dispatches as “successful deliveries,” completely obscuring client-side extension crashes, OS battery throttling, and unmeasured response latencies. In response to this industry-wide data integrity problem, Flow Vertex Core was established as an independent, engineering-led diagnostic practice focused exclusively on mobile push notification measurement pipelines, client telemetry instrumentation, and conversion attribution modeling.
Our Technical Philosophy & Approach
At Flow Vertex Core, we believe that measurement infrastructure must be as resilient and well-tested as core application business logic. Our practice operates on three core principles:
- Client-Side Verification Over Gateway Assumptions: A notification is only delivered when the mobile operating system successfully renders it on the user’s screen or executes its background payload handler. We design telemetry that verifies device-level state rather than relying on gateway assumptions.
- Deterministic Attribution Windows: We help mobile organizations replace arbitrary attribution windows with defensible, decaying models that separate direct user taps from ambient organic sessions.
- Transparent, Code-Level Deliverables: Our audits produce concrete code pull requests, architectural specifications, and reproducible packet traces rather than vague slide decks.
Technical Leadership & Engineering Team
Our Bangkok-based team brings together specialists in:
- Native iOS Systems Engineering: Deep expertise in
UserNotifications.framework,UNNotificationServiceExtension, APNs HTTP/2 protocol multiplexing, and background memory constraints. - Android Core & OEM Architecture: In-depth knowledge of
FirebaseMessagingService, Android Doze mode state transitions, OEM background process killers, and Android 13+ runtime notification permissions. - High-Throughput Telemetry Ingestion: Designing low-latency ingestion endpoints and event schemas for tracking millions of real-time acknowledgment pings.
Client Engagement Model
We collaborate with mobile product teams worldwide through structured, fixed-scope diagnostic audits and advisory retainers. Whether your engineering team is preparing for a high-volume product release, migrating push notification service providers, or resolving persistent attribution discrepancies, Flow Vertex Core provides objective, rigorous technical guidance.
