I build web applications, APIs, automation tools and backend systems.
Writing clean data models, resilient background daemons, and low-latency APIs. Currently architecting and scaling Elyriax.
Elyriax
v0.3.2 LIVEElyriax is a high-throughput digital marketplace and utility platform built for instant product fulfillment, balance accounting, game data analytics, and developer services. Designed around native browser primitives and clean REST endpoints to deliver sub-second latency with zero framework overhead.
Pre-calculated balance ledger with idempotent webhook handlers, immutable transaction audit trails, and automated 24/7 VietQR dynamic payment generation.
Lock-free inventory reservation preventing double-spending, atomic balance deduction, and immediate automated delivery of digital credentials into the user library.
Federated authentication supporting Google, Discord, and GitHub. Stateless cryptographic JWT tokens with client-side localStorage hydration and zero-FOUC state restoration.
Real-time Genshin Impact Daily Note monitoring, automatic check-in cron daemons, gacha event schedules, and local role statistics caching.
Full-stack marketplace with wallet transactions ledger, VietQR automated deposit, atomic inventory delivery, and OAuth 2.0.
Sayra Mail
PRODUCTIONTemporary disposable email routing platform utilizing Cloudflare Email Workers, D1 SQLite at edge, Durable Objects, and WebSocket push for zero-polling realtime inboxes.
Media Pipeline & Tooling APIs
DEVModular backend APIs for stream extraction, audio/video transcoding, image compression pipelines, and neural text translation across 40+ languages.
Discord Ecosystem & Automation
ACTIVEEvent-driven Discord automation for instant transaction notifications, community role synchronization, verification gates, and background daemon health monitoring.

I build things on the web, mostly around APIs, backend systems, automation, and small experimental projects. My focus is on writing clean, understandable code, designing reliable data flows, and keeping architectures fast without unnecessary framework bloat.
What I am actively spending time on and engineering right now:
Refining wallet ledger transactions, atomic checkout, and developer API service suites.
Exploring edge SQLite scaling patterns with Cloudflare D1 and Durable Objects for distributed apps.
Building resilient background workers and event stream listeners for automated community tasks.
Let's build something solid together.
