Lens931/README.md

Hi, I’m Lens93

I’m a self-taught developer from France.

Most of my work is around FiveM/QBCore, server infrastructure, defensive security, web tooling and local AI experiments.
I like building systems that are practical, readable and useful in real environments — not just impressive on a screenshot.

I’m still learning, testing and improving every day, but I try to keep one simple direction:

Build useful things.
Keep the code understandable.
Share what can help others.
Improve quietly, step by step.

What I work on

FiveM / QBCore

This is where I spend most of my time.

I build and improve resources for FiveM servers, with a focus on clean configuration, server-side logic, NUI interfaces, performance and moderation tools.

Some areas I work with:

  • Lua client/server scripting
  • QBCore resources
  • NUI interfaces
  • SQL persistence
  • Admin and moderation tools
  • Discord logs and webhooks
  • Performance-aware scripts
  • Gameplay systems for RP / freeroam environments

Server security & infrastructure

I’m also interested in server protection, monitoring and visibility.

Not from a “magic security tool” point of view, but from a practical one: logs, alerts, hardening, suspicious behavior detection and safer infrastructure habits.

Things I work on:

  • Linux server administration
  • Docker-based setups
  • Apache / Nginx reverse proxy configs
  • Fail2Ban / CrowdSec workflows
  • Web scanner detection
  • Honeypots
  • Discord alerting
  • Integrity checks
  • Basic defensive automation

Web development & tooling

I build small web platforms, dashboards, APIs and internal tools when they help a project become easier to manage.

Main tools I use or experiment with:

  • React / TypeScript
  • JavaScript
  • Python
  • FastAPI
  • Node.js
  • PostgreSQL / SQLite
  • Redis
  • Docker
  • REST APIs

Local AI & automation

I’m interested in local AI workflows, assistant-like tools and automation systems that can help speed up development without replacing understanding.

I use AI mostly as a way to structure ideas, debug faster, document better and turn rough concepts into cleaner systems.

Areas I explore:

  • Local LLM workflows
  • AI-assisted development
  • Prompt-to-system architecture
  • Automation scripts
  • Audio / media workflows
  • FFmpeg tooling
  • Self-hosted experiments

Featured projects

Visionary Shield

Open-source FiveM/QBCore admin and security toolkit.

The goal is simple: provide a transparent, auditable and practical defensive layer for server owners who need better visibility, moderation tools and staff workflows.

It includes:

  • Compact NUI admin interface
  • Player inspection tools
  • Staff actions and moderation workflow
  • Runtime monitoring
  • Screenshot evidence support
  • Config-driven behavior
  • QBCore-friendly structure
  • Documentation-first approach

Security should not be a luxury.
A small server should still be able to understand, audit and improve the tools it depends on.

qb-marketplace-community

A community-oriented FiveM/QBCore marketplace resource.

The idea behind this project is to provide a clean, configurable marketplace system that can be understood and adapted by other server owners.

Main focus:

  • QBCore integration
  • Marketplace listings
  • Sales history
  • Withdrawable earnings
  • SQL persistence
  • Discord logs
  • Configurable economy
  • Clean NUI direction

https://github.com/Lens931/qb-marketplace-community


PLANG

An experimental project around prompt structure, AI workflows and turning ideas into clearer systems.

This project reflects how I like to work with AI: not just asking for output, but trying to create repeatable workflows, better structure and cleaner development direction.

Repository:
https://github.com/Lens931/PLANG


My technical direction

I don’t pretend to know everything.
Most of my progress comes from testing, breaking things, fixing them, documenting better, and slowly improving the way I build.

What I care about:

Value Meaning
Clarity Code and documentation should be understandable later
Usefulness A project should solve a real problem
Security Logs, validation and visibility matter
Performance Avoid unnecessary loops, noise and heavy client usage
Maintainability Clean structure makes future work easier
Humility Build, learn, improve, repeat
Open-source spirit Share what can help others when possible

What I’m improving right now

  • Cleaner FiveM/QBCore resources
  • Better NUI interfaces with lower overhead
  • More readable public documentation
  • Practical server-side validation
  • Defensive tooling for smaller communities
  • Local AI workflows for development
  • Self-hosted infrastructure habits
  • Open-source releases that are easier to audit and improve
