Not a resume of technologies. These are the decisions that shaped the platforms I have led, and what each one actually changed.
The role
This is the work of a Platform Product Manager: owning the shared foundations — payments, APIs, data and AI — that other product teams build on. As a former engineer, I make the architecture trade-offs alongside engineering and tie each one to cost, speed and P&L. I'm open to Head of Product and Platform Product Manager roles in Dubai, London or remote.

Not a resume of technologies. These are the decisions that shaped the platforms I have led, and what each one actually changed.
A single deployable was blocking regional teams, coupling release trains and hiding ownership.
Split along domain boundaries with clear service ownership and a staged migration.
Accepted increased operational overhead and network complexity in exchange for independent team deployment velocity and clear domain boundaries.
Improved scalability, ownership, and platform evolution.
Synchronous chains meant one slow dependency degraded the whole order and payment flow.
Async messaging with idempotency and failure isolation.
Accepted eventual consistency and ledger reconciliation latency in exchange for strict service isolation and resilient payment checkout flows.
Created resilient workflows and reliable platform communication.
Every partner integration was bespoke, so onboarding time scaled linearly with the roadmap.
Versioned public APIs and SDKs with a governance model.
Enforced strict backward-compatibility rules and breaking-change governance, trading rapid feature rollout speed for enterprise partner integration stability.
Partner integration moved from bespoke projects to self-serve. 60% onboarding automation, 4x merchant growth.
Demos were convincing, but nothing had evaluation, cost controls or a governance path to release.
No model ships without an evaluation gate, a cost and latency budget, and monitoring.
Capped model parameter scale and context depth to preserve sub-second latency budgets and unit economics over raw theoretical accuracy.
Balanced capability, cost, reliability, and governance.
Store kitchens, field logistics and couriers face intermittent network drops, risking duplicate payment charges, lost orders or broken compliance audit trails.
Offline-first local SQLite sync, optimistic UI state updates, and idempotent queued requests for Tap to Pay and status transitions.
Zero duplicate transaction faults, resilient order intake during peak Wi-Fi drops, and real-time auditable compliance.
