Now

A snapshot of what I'm currently building, operating, and thinking about.

Last updated: February 2026

Operating

Running production infrastructure at Hypercape Inc.—K-beauty commerce platform serving cross-border supply chain operations.

  • Stabilizing Shopify-integrated fulfillment pipelines
  • Enforcing idempotency across order and inventory mutations
  • Building audit trails for every critical state transition

Building

Architecting systems and tooling across Hypercape and WeKlem.

  • Supply-chain data model redesign with strict SSOT enforcement
  • Internal admin tooling with role-based access and IP restrictions
  • Cross-platform mobile apps at WeKlem (React Native, Flutter)

Documenting

Writing engineering knowledge as operational tools, not artifacts.

  • Migration playbooks for every schema change
  • ADRs (Architecture Decision Records) as team memory
  • Publishing engineering insights on mandarange.dev

Learning

Exploring patterns at the intersection of distributed systems and AI-assisted development.

  • Event-driven consistency models for eventually-consistent pipelines
  • AI-agent workflows that leverage machine-readable documentation
  • Observability patterns for complex multi-service architectures
