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.
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 |
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. |
Porting modern postmarketOS Linux and custom recovery to the Samsung Galaxy J1 Mini ( | 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. |
