AJA RETRO
Ahmed Juhaed Ayeman Niloy
Intro
I am a systems engineer and security researcher specializing in virtual machine-level hardening, multithreaded backend architectures, and interactive virtual environments.
My engineering work focuses on low-level JVM instrumentation, runtime sandboxing, and building distributed systems. Outside of code, I am a competitive strategy gamer and a vocalist performing rock and metal covers inspired by my favorite band, Warfaze.

Flagship Projects
Secure in-game email registration, verification rewards, and Web Dashboards built for modern Spigot & Velocity proxy setups.
High-performance regional multithreading library supporting asynchronously scheduled commands, region-locking checks, and optimization utilities.
Lag prevention sentinel that monitors server tick speeds and automatically quarantines/throttles heavy threads during performance drops.
Geyser/Floodgate-aware item rendering layer that aligns Totem animation packets with Bedrock client screen parameters.
Intelligent chunk purging and region file storage optimizer designed to safely discard empty or unmodified chunks upon unload on Folia and Paper.
Fields of Expertise
JVM & Systems Eng
Low-level JVM instrumentation, writing custom ClassLoaders, regional multithreaded task scheduling (Folia/Paper), and real-time bytecode manipulation using OW2 ASM.
Security & Hardening
Designing zero-trust runtime sandboxes, blocking command/process spawns, whitelisting JAR protecting domains, and implementing cryptographic licensing relays.
Full-Stack Systems
Developing FastAPI web interfaces, telemetry log databases, and custom dashboard modules for Pterodactyl/Pelican hosting panel architectures.
UE5 Game Dev
Designing interactive worlds, implementing C++ engine subsystems, and coding complex game state mechanics inside Unreal Engine 5 at Sheikh Games.
Competitive Meta
Casual competitive player and strategy theorist. Analyzing game meta, frame timings, and tick performance margins under high-intensity network situations.
Vocal Performance
Self-taught vocalist performing rock and metal covers. Deeply inspired by bands like Warfaze, focusing on vocal range and breath control.
