// why we built it

Data modeling is the highest-leverage decision in a complex platform. The 185-table schema took two weeks to design before any code was written. Every subsequent feature built cleanly on top of it — a validation of the "architecture first, code second" discipline. Nexural is also the source of the micro-saas-starter template and three other open-source infrastructure patterns now used across the studio.

// what it does
  • Real-time portfolio dashboard with live price feeds via WebSocket connections and Supabase realtime subscriptions
  • Trade execution interface with order management and position tracking
  • Discord AI bot backed by GPT-4 — handles portfolio queries, market commentary, and alert management in natural language
  • Stripe subscription billing with tiered access, trial periods, metered usage, and idempotent webhook handling
  • 61 test suites covering unit, integration, E2E, contract, and security layers

Surface proof, system proof.

Nexural is a studio proof object: not just a concept page, but a real product with a problem, stack, operating thesis, and route into deeper case-study proof when available.

Product ⇄ Engine

Serious traders are underserved by both consumer apps (too simple) and enterprise platforms (too complex and ops-heavy). There was no middle ground for technically sophisticated individual traders who wanted full control without the overhead.
