Building Resilient Distributed Systems & Financial Architectures.
I'm Erlando Aubrey — a hands-on Senior Backend & Infrastructure Engineer with 8+ years of experience. I design high-throughput trading platforms, eliminate deployment risks with modern CI/CD, and build financial ledgers where not a single cent can go missing.
The Broken Exchange
Try exploiting a financial ledger. Trigger concurrent double-spending race conditions, floating-point rounding drift, and network retry storms against a live zero-sum ledger.
Friday 5 PM: The Hotfix
A critical payment bug is reported in production at 4:58 PM on Friday. Choose your workflow: edit directly on the live server, or deploy via local-first Git and Docker Swarm.
Queue & Latency Lab
Watch how decoupled message brokers (RabbitMQ / LavinMQ) absorb sudden 5x traffic surges with backpressure, versus synchronous REST HTTP that crashes under load.
State Machine & Battle Resolver
Play a digital TCG combat timing pipeline. Test strict finite state machine (FSM) phase validation, seed-based deterministic RNG drive checks, and cryptographic state hashing.
Tetris & The Talos Principle Sigil Solver
Interactive polyomino exact-cover tiling engine designed for tetromino packing and The Talos Principle sigil puzzles. Solves dynamic grids using recursive backtracking with island gap pruning, checkerboard parity checks, and live hover cell inspection.
Huffman & Hex Stream Compressor
Interactive file compression engine based on peer-reviewed academic research published by Erlando Aubrey Nathaniel (DOI: 10.33197/jitter.vol5.iss3.2019.295). Experience dynamic prefix-free tree generation, entropy analysis, and binary-to-hexadecimal stream serialization.
Deep Q-Network Signal Recommender
Interactive reinforcement learning engine based on Erlando's undergraduate thesis: Personalized Trading Signal Channel Recommendations. Simulates Nguyen-Widrow neural weight initialization, live Q-score feedback loops, and 94% recommendation diversity.
