SYSTEMS ENGINEER · SEOULAVAILABLE FOR SERIOUS SYSTEMS

Discover direction.Keep memory.Stay alive.

From agent judgment to real-time characters and operational backends, I design systems that preserve evidence, recover from failure, and improve over time.

SELECTED SYSTEMS / 2026

Structure before claims.

PALAMEDESRESEARCH ALPHA

P—01

Before tasks,
choose the mission.

A local-first mission intelligence layer that discovers and reviews what is worth pursuing before execution agents plan how to build it.

Verified evidence: Revisionable plan-state kernel, bounded handoff, and 8 of 9 votes in an origin-blinded model review.
Current boundary: Research Alpha. Better external outcomes and human-level creativity are not proven.

GAHYEONACTIVE DEVELOPMENT

Gahyeon character portrait — ONE CORE · DISCORD · DESKTOP · UNREAL

G—02

One mind,
many presences.

A multi-client system where one Core appears as a voice assistant in Discord and as a persistent real-time AI character on Desktop and Unreal.

Verified evidence: Separated Core/Application/Adapters, persistent World, bounded runtime, and Desktop/Unreal protocols.
Current boundary: Packaged Unreal acceptance, the final hero mesh, and physical-device verification remain in progress.

ONE PRACTICE / TWO SYSTEMS

Decisions leave a record. Execution keeps its boundaries.

Palamedes and Gahyeon are different products with the same discipline: preserve state, separate authority, and return failure as input to the next decision.

Separate evidence from inference
Preserve approval and execution authority
Return outcomes to persistent state

SYSTEMS IN PRACTICE

From the first screen to the last production alert.

I work across Java and Spring backends, React interfaces, PostgreSQL, Redis, Kafka, and container operations as one product flow.
