Building activelyMegami · Seasonly · BrumeKamiyama

I build products at the intersection of consumer entertainment culture and systems engineering. Megami, a Discord economy bot with full relationship mechanics — ownership, trading, marriage, and a community drama feed. Seasonly, a fantasy league platform for seasonal entertainment drafts — users predict their top picks and score against real performance data. Brume, a Rust realtime gateway that competes with Pusher and Ably but is entirely self-hostable and DB-agnostic. I care about products that are honest, well-crafted, and solve problems that actually exist.

01 — About

What I'm about.

The thinking behind the projects and how I approach building.

Domain depth first

I study the domain before touching code. The quality gap between most software and what practitioners actually need is almost always a knowledge problem, not a technical one.

Privacy by design

I think carefully about what data should and should not leave a user's machine — not as a compliance checkbox, but as an architectural constraint from the start.

Lean infrastructure

Tight budgets force better decisions. I build with the smallest footprint that meets the requirement, and treat every unnecessary dependency as a liability.

Ship, then refine

A working version in front of real users is worth more than a perfect architecture in a design doc. I move fast on the first version and let actual use reveal what matters.

Working principles

  • Understand the domain before writing a line of code.
  • Privacy is a feature, not a compliance checkbox.
  • Ship a working version before optimising the architecture.
  • Find the gap in existing tools — build replacements, not clones.
  • Treat every unnecessary dependency as a liability.

Let's talk.

If you have an idea, want to collaborate, or just want to talk about anime culture, gacha economies, fantasy sports, or distributed systems — reach out. I'm always interested in good conversations.
