Profile

Systems Architect and Backend Developer specializing in the engineering of custom, resilient distributed systems for live-service environments. My core achievement is the development of the XRohrJS framework, a Dual-Server architecture utilizing an in-memory Memoria Cluster to master concurrency and ensure Atomic State Transitions under high load. I am motivated by complex performance challenges and am committed to delivering scalable, near-zero downtime solutions using TypeScript, Node.js, and MongoDB.

Personal Projects

Systems Architect & Core Contributor (XRohrJS)Bandung, Jawa Barat, Oct 2025 — Present
  • Engineered a custom Node.js framework supporting a Dual-Server Architecture (Control/Data Plane) to ensure service continuity and resilience in live-service applications.
  • Designed and implemented the Memoria Cluster (In-Memory Database) with a per-key Mutex lock to manage concurrency and ensure Atomic State Transitions under high load.
Game Systems Modeler & Developer (Armorize)Bandung, Jawa Barat, Apr 2025 — Present
  • Modeled a high-risk, player-driven economy featuring Guild Liquidity Pools to validate the concurrency and transaction capabilities of the custom backend.
  • Designed a flexible data schema for complex entities (Mystar Attributes, Traits, Equipment) demonstrating expertise in non-relational database structure.

Profile

A backend developer with a strong focus on software architecture and distributed systems. Developed XRohrJS, a proprietary Node.js framework for high-concurrency situations. Our expertise lies on developing durable, self-healing backend infrastructures and handling complicated states via in-memory clustering. Seeking to use extensive technical understanding of TypeScript and Database Design to create scalable web applications.

Software Engineering Projects

XRohrJS Framework (Core Architect)Oct 2025 — Present
  • Architected a custom Node.js/TypeScript framework utilizing a Dual-Server Model(Control & Data Plane) to eliminate downtime during runtime updates.
  • Developed Memoria Cluster, an in-memory database engine with Mutex locking mechanisms to handle atomic state transitions and prevent race conditions in high-traffic scenarios.
DiscrafterJS Framework (Creator & Lead Maintainer)Sep 2025 — Dec 2025
  • Created an opinionated TypeScript framework based on Discord.js to ensure architectural consistency, addressing boot-up logic complexity through the strict separation of configuration and business logic.
  • Developed an Asynchronous Factory Pattern to ensure reliable asynchronous object initialization and established a Config-Driven Architecture to function as the authoritative source for environment management.
