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
