Hi there, I'm Abi 👋 (@trefeon)

Systems & Software Engineer · Embedded & IoT Developer · AI Tooling Builder

I build high-performance network proxies, resilient AI developer tooling, embedded IoT platforms, and low-level Linux systems. My work focuses on solving real operational friction—turning complex protocols, edge hardware, and distributed services into reliable, observable, and automated solutions.


🚀 Featured GitHub Projects

🤖 AI Engineering, Proxies & Developer Tooling

High-performance, OpenAI-compatible gateway for FreeBuff coding models. Features token pooling, session lifecycle tracking, TLS stealth/browser fingerprinting, and an embedded real-time web admin dashboard for Cursor, OpenCode, and VS Code.

Fast reverse proxy that exposes AgentRouter's Claude and OpenAI models as a local OpenAI API endpoint. Implements WAF bypass, dynamic header spoofing, automatic model health routing, and one-line cross-platform installers.

Zero-config CLI and linting engine scanning prose, UI design, and source code for repetitive AI-generated patterns and slop across 389 rules in 7 specialized domains.

Universal compatibility patch resolving Antigravity IDE language server SIGILL crashes on older CPUs lacking modern instruction sets via transparent QEMU user-mode emulation.


⚡ Embedded Systems, IoT & Hardware Automation

Distributed MQTT IoT concentrator platform connecting an ESP32 concentrator, ESP8266 bridge nodes, a high-throughput FastAPI backend, and a modern React operations dashboard.

Commercial arcade rental timer system for RC excavators operating in retail venues, utilizing a synchronized ESP32 Wi-Fi Master-Slave architecture for reliable countdown and power relay cutoffs.

End-to-end IoT telemetry and device monitoring platform powered by MQTT message brokering, asynchronous FastAPI processing, Nginx reverse proxying, and containerized Docker services.

Railroad crossing protection system simulation with real-time sensor ingestion, fail-safe interlocking logic, and desktop visual telemetry.


📱 Mobile OS, Kernel Porting & Low-Level Systems

Porting modern postmarketOS Linux and custom recovery to the Samsung Galaxy J1 Mini (SM-J105F / j1minilte), enabling mainline Linux experiments on legacy mobile hardware.

Vendor Linux 3.10 kernel source tree and driver patchset adapted for Samsung Galaxy J1 Mini hardware bringup and embedded Linux booting.

Custom Team Win Recovery Project (TWRP) device tree for SM-J105F with automated build pipeline configured via GitHub Actions.

Practical guide and tooling for setting up lightweight Docker and containerized Linux workflows directly inside Android Termux environments.


🛡️ Security Auditing & Enterprise IT Operations

  • Prototype-IoT-Pentester — Comprehensive hardware & wireless security toolkit for auditing IoT devices across Wi-Fi, BLE, NFC, and RFID attack surfaces.
  • wifi_pentesting_project — Modular wireless network testing framework focusing on passive frame capture, beacon analysis, and radio diagnostic routines.
  • enterprise-ops-monitor — Operational dashboard inspired by enterprise support workflows: infrastructure monitoring, system health checks, backup verification, and RBAC reporting. (React · Node.js · PostgreSQL · Docker)
