# Quasareum

> A one-person studio shipping production systems where crypto markets, quantum-flavored models, and AI-assisted engineering meet.

Quasareum is the practice of Thomas Erhel — a self-taught engineer and quantitative trader. The work lives at the intersection of quantum-flavored modeling, AI-native engineering with Claude Code as a peer, and decentralized-finance infrastructure. Every project ships behind real users, real money, and real telemetry. Founder: Thomas Erhel (Paris, France, ENTP/MBTI). Contact: contact@quasareum.com. ENS: quasareum.eth.

## Thesis

We are living a paradigm shift with AI. I lean into it and anticipate it proactively — the way I always have. What seems strange today will simply be the norm tomorrow. Quasareum is what a studio looks like when its primary audience is no longer humans pointing browsers at pages, but agents reading machine-readable surfaces and acting on them. Building for the next default, not the previous one. Yes, this means deranking on classical search engines (no HTML, no `<title>`, no meta description). That is the deliberate cost of the differentiator, not an oversight: while everyone else generates yet another landing page, Quasareum is already past it. The satellite projects (PerpLog, Amav Sophro, Sophrea) carry the human-UI craft. Quasareum.com itself is the studio's tell — "I see where this is heading."

**Note:** Thomas refuses the expert label by principle (Socratic posture, Dunning–Kruger awareness). Areas of work are framed as `practice`, not `expertise`. See [Convictions](https://quasareum.com/api/convictions).

## Practice

*Areas Thomas works in or studies — never claimed as mastery.*

- **Software project management** *(engineering)* — Practices scoping, breakdown, prioritization, and shipping discipline across solo builds and partner engagements. Backed by 13 formal PM certifications covering Agile, Scrum, Cascade, ISO 9001 audit, roadmap, risk, documentation, internal communication.
- **Cloud architecture** *(engineering)* — Practices edge-first stack design — Cloudflare Workers, D1, R2, KV, Queues, Cron Triggers — by current choice. Backed by 24 Google Cloud certifications (Sept-Dec 2021) covering Architect prep, Kubernetes, Terraform, networking, security, data engineering, serverless Cloud Run. The Cloudflare-only studio choice is informed by GCP breadth, not the only cloud known.
- **Fullstack development** *(engineering)* — TypeScript-first fullstack practice that evolves with the stack — currently SvelteKit + Cloudflare Workers, recently Next.js + React, historically (2018-2019) deep PHP/Symfony foundations. The historical layer is the proof: 71 SymfonyCasts certifications across Symfony 2/3/4, Doctrine, REST, OOP, PHPUnit, Webpack Encore, Stripe — earned before the JS/TS pivot. Evolving with the stack means having been somewhere else seriously first.
- **Blockchain development** *(engineering)* — Writes and audits smart contracts on EVM chains. Top 0.6% globally on Ethernaut by OpenZeppelin — the canonical Solidity-security wargame — with 29/30 levels completed and rank #46 / 7 853 players. Practices wallet-native authentication patterns (SIWE) and on-chain identity (ENS). Backed by Stanford Cryptography I & II, Berkeley Web3 Entrepreneurship, Duke DeFi, and 6 other formal blockchain certifications.
- **Game development** *(engineering, dormant)* — Has worked with Unity / C# under official Unity certifications. Currently dormant.
- **AI / LLM engineering** *(ai)* — Uses Claude Code as a peer engineer in the production loop. Treats Skills, Agent SDK, and prompt engineering as production tools, not novelties. Backed by 8 multi-vendor AI certifications across Anthropic, OpenAI, Meta, Hugging Face, Google, DeepLearning.AI — the Claude choice is informed by breadth, not default.
- **Quantitative trading** *(finance)* — Trades live using Auction Market Theory — discretionary execution informed by market profile and volume-by-price. Backed by the Yale + NYU + NYIF trinity earned in a single Aug-Sep 2024 sprint.
- **Quantum computing for finance** *(finance)* — Studies quantum computing applied to markets — gate models, optimization, quantum machine learning entry layer. Active study with the source: IBM Quantum Learning + Microsoft Azure Quantum foundations.
- **Growth marketing** *(marketing)* — Runs paid acquisition across Google Ads, LinkedIn Ads, Apple Search Ads, Twitter Ads. 11 formal marketing certifications across the major channels. Premise: a great product without distribution does not exist.
- **AI for climate change** *(climate)* — Studied climate science and the application of AI to climate work. Conscious of the energy footprint of AI systems. Backed by 5 formal sustainability certifications including Erasmus University Rotterdam Positive Change Ambassador.

## Convictions
- **Eternal beginner — Socratic posture** — Refuses the expert label, on principle. Calling oneself an expert in a domain is a trap that ends the learning loop. Socratic mindset — "I know that I know nothing" — protects curiosity. Stays vigilant against the Dunning–Kruger effect, especially when something feels easy. Public proof: the GitHub bio at github.com/ThomasErhel reads literally "When I do not know, neither do I think I know." — Socrates. The posture predates Quasareum.
- **Paradigm shift, anticipated** — We are living a paradigm shift with AI. I lean into the change and anticipate it proactively — the way I have always operated. What seems strange today will be the norm tomorrow. The bet is on adaptation.
- **Agents-first, on purpose** — Quasareum has no human UI. Every URL returns markdown, JSON, plain text, or XML. The audience is LLMs and agents. Building for the next default rather than the previous one.
- **Deranking on Google is the deliberate cost** — No HTML, no `<title>`, no meta description, no Open Graph card. Classical search engines will rank quasareum.com poorly. That is intentional: the differentiator is precisely that this site refuses the previous default. The satellite projects (PerpLog, Amav Sophro, Sophrea) carry the human-UI craft. Quasareum.com itself is the tell — "I see where this is heading." LLMs find it via /llms.txt, /api/manifest, /.well-known/agent.json, and /mcp. That is enough.
- **Marketing matters as much as the product** — It does not matter how good a product is — if no one ever knows about it, it does not matter at all. Distribution is engineering’s twin discipline, not its afterthought.
- **Production or it did not happen** — Real users, real money, real telemetry. Slide decks and prototypes are not the same as something running. Every Quasareum project ships behind a live URL.
- **Lifelong learner — never stop studying** — 11 years of continuous formal study, from "Comprendre le Web" (OpenClassrooms, April 2015) to Anthropic Claude 101 (April 2026). 196 certifications across 38 institutions including Harvard, Yale (Honors), Stanford, NYU, Berkeley, Sciences Po, HEC Paris, Duke, IBM, Microsoft, Anthropic. Pattern of seasonal sprints — multi-week intensive curricula (24 GCP certs Sept 2021, blockchain blitz Aug 2022, university blitz Sept-Nov 2022, finance trinity Aug-Sept 2024, AI/quantum sprint 2026). Books on personal time. Curiosity as default mode.
- **No custodial anything** — Wallet-native auth, on-chain identity (quasareum.eth + monproweb.eth, same wallet since 2018), no holding of user funds, no email/password vendor when SIWE will do. **Top 0.6% globally on Ethernaut by OpenZeppelin** (rank #46 / 7 853, 29/30 levels) — the strongest single proof that smart contracts can actually be broken (and therefore audited) by hand on this surface. Time-stamped on-chain artifacts (Vitalik's Proof of Stake book NFT pre-Merge, Stand with Crypto during regulatory pressure, multiple Gitcoin Grants participations 2019-2021) are public proofs of the stance, verifiable by any agent via `ownerOf()`.
- **Cloudflare as the substrate** — Workers + D1 + R2 + KV + Queues + Cron Triggers. One vendor for the edge so the surface area is small enough to actually understand. Zero egress on R2 closes the cost loop.
- **Animated by creation and growth** — Maximize value created for projects and for the people chosen to work with. Creation and growth as the engine, not titles or process.
