Now

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

Last updated: October 2026

Operating

Running production infrastructure at Hypercape Inc.—global K-beauty distribution and fulfillment platform for Shopify sellers, brands, and creators. Products ship globally from Korea.

  • 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, plus open-source AI agent infrastructure.

  • Supply-chain data model redesign with strict SSOT enforcement
  • Internal admin tooling with role-based access and IP restrictions
  • Evolving Sneakoscope Codex (evidence-gated AI coding agent harness)

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, AI-assisted development, and verifiable agent workflows.

  • Event-driven consistency models for eventually-consistent pipelines
  • Evidence-based AI agent frameworks (proof over claims)
  • Observability patterns for complex multi-service architectures
