About

A short note about my background, work, and current direction.

I was exposed to financial markets, computers, and digital tools relatively early. Those early interests made me pay attention to how information moves, how tools change behavior, and how markets respond to new technologies.

During my undergraduate stage, I studied in a media and communication context. That experience made me look beyond content itself and pay more attention to production workflows, technical systems, visual presentation, and how information reaches an audience.

My current work brings these interests together through research, analysis, data visualization, and visual communication. Critical Mass is the main outlet for this work at the moment. I use it to organize my observations on AI infrastructure, semiconductors, and technology markets, and to turn scattered information into more readable analytical content.

Over time, I hope this work can reach a broader audience and become more useful to people trying to understand technology, markets, and the systems behind them. For now, it is still a personal research and expression space, but I want it to move toward clearer, more accessible explanations.

This website is a compact index of selected projects that represent my current direction. It connects my work in research, analysis, visual communication, and media-related systems. The approach doesn't change across systems — only the scale of the questions does.

Critical Mass

An independent research system tracing where technology stories begin to pressure the real world, when that pressure becomes measurable demand, and how the result distributes value, capital, bottlenecks, and risk.

Technology story → real-world pressure points → real demand → who benefits, pays, controls, and carries risk — tested against issuer-level filings and written up as framework essays.

Research Focus

The work here moves across technology markets, AI systems, and information design — connected by a single question: how do structural constraints shape what a system can do, and what that means for the people reading it.

AI Infrastructure

Compute, platforms, and infrastructure constraints behind AI adoption.

Technology Markets

Business models, competitive positioning, and market signals.

Media Systems

Sound, production workflows, technical systems, and digital media infrastructure.

Information Structuring

Turning scattered information into usable analytical structure.

Capabilities

A working set of analytical, technical, and communication skills used across research projects.

Business & Market Analysis

Company, industry, and market-structure analysis. Core methodology throughout Critical Mass.

Data Structuring

Organizing messy information into comparable datasets, notes, and evidence maps. Implemented with Python for source collection and structured comparison.

Visual Communication

Turning analytical findings into clear visual and web-readable formats. Presented through charts and layouts optimized for web reading.

Media & Technology Systems
