I am a backend-focused software engineer with experience in:

• high-throughput and concurrent backends
• distributed systems and microservices
• secure data and file pipelines
• real-time APIs and integration work

I primarily work with Java, Go, and Node.js/TypeScript, and I care a lot about reliability, observability, and production-readiness rather than throwaway demos.

• Design and implementation of REST / JSON APIs and backend services
• Java (Spring-based backends, messaging, persistence)
• Go (microservices, workers, concurrency patterns)
• Node.js / TypeScript (APIs, bots, tooling)
• Data stores: PostgreSQL, Redis
• Containerization and dev tooling: Docker, Linux
• Secure handling of user data and files, including encryption and access control

Repository: https://github.com/waifuvault/WaifuVault

• Production-grade secure file hosting platform currently serving 3,769+ public files with a total footprint of 55.32 GiB
• Backend built with Node.js / TypeScript, with supporting services and infrastructure components
• End-to-end encrypted file storage with temporary, permission-based access links
• Streaming-first architecture for uploads and downloads to avoid loading large files into memory
• Data layer powered by PostgreSQL with Redis for caching, rate-limiting, and transient state
• Fully containerized with Docker, enabling reproducible local and production deployments
• Designed with a focus on:
  • security-by-default
  • horizontal scalability
  • fault isolation
  • and operational monitoring

This project is actively used in production and serves as a real-world backend systems testbed.

Repository: https://github.com/VictoriqueMoe/umineko_city_of_books

• Full-fledged social networking platform for fans of the When They Cry visual novel series (theory debates, game board, mysteries, galleries, fanfiction, chat rooms, DMs, and more)
• Backend in Go (Fiber v3) backed by SQLite (pure-Go, no CGO), frontend in React 19 + TypeScript, served as a single binary embedding the Vite bundle
• Real-time everything over a single in-process WebSocket hub: live notifications, chat, presence, reactions, and like/view counters with exponential-backoff reconnect and ETag polling fallback
• Background media pipeline with a worker pool for image-to-WebP and video-to-MP4 encoding off the request hot path
• Permission-based authorization layer, server-side sessions with httpOnly cookies, and a pluggable content-filter pipeline on all user-generated text
• Live at meta.auaurora.moe

Repository: https://github.com/VictoriqueMoe/umineko_quote_finder

• Search engine over thousands of dialogue lines across three visual novels (Umineko, Higurashi, Ciconia), with filtering by character, episode/arc/chapter, and truth type
• Go (Fiber v3) backend with a hand-written lexer → parser → AST → transformer pipeline for parsing the game scripts, plus a generic store for shared search/browse/random logic
• Custom ONS2 format decoder (XOR substitution cipher + zlib), data embedded at compile time via go:embed, and on-the-fly Open Graph image generation for shareable quotes
• React 19 + TypeScript frontend with inline audio playback and a voice-clip builder for composing custom dialogue sequences
• Containerized with Docker and shipped via GitHub Actions; live at quotes.auaurora.moe

Repository: https://github.com/VictoriqueMoe/onscripter-ru-wasm

• WebAssembly fork of the C++ ONScripter-RU visual novel engine, cross-compiled to run entirely in the browser via Emscripten
• Replaces multithreaded subsystems (media demux/decode, subtitle rendering, async dispatch) with single-threaded synchronous equivalents to fit the browser execution model and WASM memory limits
• Rewires native synchronous file I/O to fetch assets over HTTP on demand, and persists save data to the browser's IndexedDB via IDBFS
• Adapts the graphics and audio pipelines to WebGL and the Web Audio API, with all changes gated behind compile flags so native builds stay untouched
• Powers a full PS3-build Umineko no Naku Koro ni running in a single browser tab

(More projects are available in the pinned repositories section on the profile.)

• Active contributor to personal and open-source projects
• Experience working across multi-repo, multi-service environments
• Comfortable reading, refactoring, and extending existing codebases in Java, Go, and Node
• Regular use of GitHub workflows, pull requests, and code review practices
