Hi, I'm J 👋

If it's broken, I fix it. If it doesn't exist, I build it. | AI, TS/JS, Python, Embedded HW

🛠 About Me

I'm a tinkerer, elite troubleshooter, and full-stack developer. With over 20 years of experience in troubleshooting complex issues (currently specializing in Ericsson/Nokia RAN), I've built a career on solving complex hardware issues, developing technical standards, and training teams.

Recently, I've merged my engineering mindset with modern software development. I specialize in AI integrations, API orchestration, and bridging the gap between digital tools and physical hardware.

💻 Tech Stack

• Languages: Python, TypeScript, JavaScript, HTML/CSS, C, Assembly
• Frontend: React, Tailwind CSS, shadcn/ui, Vite, Zustand
• Backend/Systems: FastAPI, Node.js, SQLAlchemy, REST APIs, Hybrid Async/Sync execution
• Hardware & Embedded: Microcontroller programming, POS/Receipt Printers (ESC/POS protocol)
• Integrations: Discord API, Shopify API, OAuth 2.0, Docker, SQLite/PostgreSQL

🚀 Featured Architecture & Projects

(Repositories are kept private, but here is a look under the hood at my systems design!)

1. "Day Printer" Task Ecosystem

A full-stack task management platform that bridges digital organization with physical hardware.

• The Concept: A modular task manager that automatically formats, schedules, and prints your daily workload directly to a thermal receipt printer (Epson TM-M30).
• Full-Stack Orchestration: Built with a modern React/TypeScript frontend and a Python/FastAPI backend using a modular service pattern.
• Hardware Bridge: Engineered a custom printing module that communicates over Network/USB/Serial. It parses task data, formats it using the native ESC/POS protocol, and includes a custom algorithm to generate accurate ASCII print-previews in the web UI.
• Discord Integration: Built a custom Discord bot that hooks into the backend REST API, allowing users to remotely create tasks, manage projects, and trigger physical prints via slash commands.

2. Sierra Chart Alert Monitor

A high-performance, low-latency pipeline bridging local Sierra Chart instances with Discord for customized alert management.

• Decoupled Systems Architecture: Built as a standalone service to isolate monitoring logic from the trading platform, preventing UI lockups and ensuring zero-loss alert processing.
• Hybrid Concurrency: Engineered a custom pipeline that seamlessly orchestrates asynchronous event loops (discord.py, Textual TUI) alongside synchronous, thread-safe file I/O (watchdog) without blocking the main thread.
• Custom TUI Dashboard: Built a fully reactive, live terminal dashboard using Textual that surfaces real-time system health, latency sparklines, and active bot logs.
• Smart Parsing & Rate Limiting: Includes dynamic screenshot correlation (matching local .png creation times to log files) and per-symbol rate throttling.
