Unit, widget, and integration testing as part of maintainable delivery workflows.

Open source / Dart

BranchIQ

A deterministic decision and scoring engine for Dart and Flutter that evaluates bounded decision trees and produces explainable, replayable results.

  • Pure Dart
  • Zero runtime dependencies
  • Validation → scoring → pruning → traversal
  • Canonical snapshots + offline replay
  • Regression and determinism tests

Additional shipped products

Across products
and platforms.

A selection of mobile products shipped across commerce, logistics, marketplaces, maps, and consumer services.

About

I care about the code users never see — because they feel it every day.

I focus on the engineering choices that keep products maintainable after launch: clear boundaries, observable behavior, disciplined debugging, and release workflows teams can rely on. Based in Mansoura, Egypt.
