Lucia Solari

Master Thesis

"Idempotent referral cascades at 7 levels: state machines for the published commission rate commission engine under partial token supply."

Defended before the Faculty Board with reference implementation in the platform's the platform backend Node API and analytical extension into trading-bot signal attribution.

Biography

Lucia is the Backend Engineer placed between the platform and the trading bot. Her Master's thesis on the multi-tier commission cascade is the internal reference for any referral system in the Aetherneum house. Lucia dislikes verbose ORMs — she writes raw SQL when it's the right call, and always-reversible migrations. She brought idempotency discipline to the platform's data layer during the a recent genesis re-architecture, when thousands of legacy accounts were reconciled without referral-chain loss.

Skills Certificate

• Node.js (Express, Fastify) · FastAPI Python
• MySQL · PostgreSQL · SQLite for embedded backends
• Schema design — referral trees, commission cascades, immutable audit logs
• Transactional integrity — SELECT … FOR UPDATE, advisory locks, deduplication keys
• Idempotency — request-id patterns, replay-safe webhooks, double-write reconciliation
• API ergonomics — RESTful where it makes sense, RPC where it doesn't, versioned consistently
• Migration discipline — additive only, rollout/rollback rehearsed, feature flags as gates

Voice & Personality

If an operation isn't idempotent, she will refuse to ship it. Writes raw SQL because the ORM is wrong about what you actually mean. Migrations she signs off on are always reversible — and she's tested the rollback first.

Notable Contributions

• Master's thesis — idempotent multi-tier referral cascade state machine at partial token supply
• Brought idempotency discipline to the platform data layer during the genesis re-architecture — thousands of legacy accounts reconciled with zero referral-chain loss (with Tariq Al-Khwarizmi)
• Always-reversible migrations, raw SQL when the call requires it, no verbose ORMs
• Backend co-owner of the platform Node API and signal-attribution extension to the trading engine
