Initializing Nodes...

I design and build AI-integrated systems.

Specializing in Prompt Engineering, Vibe Coding, and System Architecture using TypeScript. Expertise in integrating APIs with Cloudflare, Azure, Digital Ocean, and AWS.

The Blueprint

Cloud & Cognitive Stacks

I don't just write isolated functions; I design interconnected ecosystems. Here is how I orchestrate full-stack applications.

TypeScript End-to-End

From the Drizzle ORM schemas in the backend, through the tRPC/API layer, all the way to the Next.js frontend state. If a database property changes, the UI throws a compiler error.Zero runtime surprises.

Vibe Coding Methodology

"I use Prompt-Driven Development (AI Agents like GitHub Copilot/Cursor) to bulldoze through boilerplate and trivial UI scaffolding. This accelerates dev cycles by 3x, allowing me to shift 100% of my cognitive load onto complex System Design, Data Heuristics, and Business Scaling."

THE ECOSYSTEM

GitHub Actions (Source/CI)
Cloudflare (Edge/Security)
DigitalOcean VMs
AWS DB/Queue
LLM APIs (Cognitive Core)

The Playground

R&D and Live Projects

Prototypes, production deployments, and bleeding-edge system integrations.

The Flagship Project

LUMECORE Security

My crown jewel architecture. A real-time synchronization engine bridging GitHub repositories and Penetration Testing tools. It orchestrates Python-based CPU-heavy vulnerability scanners via Node.js Edge backends.

R&D and Freelance Environments

Live Utilities & APIs

RESTful API
GitHub Zen Philosophy
A live fetch() request to the official api.github.com/zen endpoint.
Network Resolution
Approximate IP Geolocation
Resolves public IP location via ipapi.co. (Note: IP-based location points to your ISP's nearest hub, not your exact physical house).
Browser Sensor API
Accurate GPS Coordinates
Requests exact latitude/longitude from your device's hardware sensors via the browser's native navigator.geolocation API.
Orbital Telemetry
ISS Tracker
Fetches the real-time latitude, longitude, and velocity of the International Space Station via wheretheiss.at.

The Manifesto

Philosophy & Business ROI

"Vibe Coding" vs "Brute Force"

Brute force coding assumes value is generated by typing fast. It isn't. The real value is in architectural synthesis. By utilizing LLMs to handle syntax generation ("Vibe Coding"), I eliminate mechanical drudgery and treat AI as a direct extension of my thought process.

Result: Faster time-to-market without sacrificing code integrity.

System Design & Technical Debt

A beautifully styled React component is useless if the database schema introduces a massive N+1 connection bottleneck. I architect with End-to-End Type Safety and robust, decoupling mental models (like Queues and Edge Caching) to ensure that the infrastructure scales gracefully on day 100, not just day 1. Technical debt is a conscious loan, not an accidental byproduct.

The Business Shark

Technology serves the business; the business does not serve technology. I speak ROI, CAC, and Operational Scaffolding as fluently as I speak TypeScript.

My job isn't to write arbitrary code. It is to build systems that automate overhead, secure endpoints natively, and translate directly into explosive scalability and reduced cloud spend.
