Aryella – Next.js, React, Typescript

A full-stack SaaS platform that enables users to build, test, and compare algorithmic trading strategies without risking real money. The platform provides statistically grounded insights into whether a strategy has a genuine edge, delivering results quickly enough to support an interactive user experience. It features isolated backtesting environments for each user, live result streaming, a no-code strategy builder, and strategy rankings based on statistical confidence rather than profit alone.

• Founded and solely built PerpForge, a commercial freemium SaaS that lets traders backtest perpetual-futures strategies against real market history and rank them by statistical confidence of edge rather than raw profit.
• Owned the full product lifecycle end to end: strategy, positioning, engineering, deployment, and go-to-market.
• Defined the product's differentiator: a rigor-first, anti-hype simulator that quantifies whether a strategy's edge is real or luck before capital is risked.
• Designed and built a deterministic backtesting engine modeling trading fees and forced liquidation over real BTC/ETH/SOL perpetual-futures candles across seven timeframes (1m–1d).
• Engineered the analytics core: per-trade Sharpe ratio with confidence intervals, max drawdown depth/duration, and confidence-of-real-edge ranking via the Sharpe CI lower bound.
• Architected a multi-tenant SaaS backend (TypeScript, Hono, Postgres) enforcing per-user data isolation on every route and query, with tier-based access limits.
• Built a fleet-scale replay scheduler handling 1500+ concurrent strategies under a shared comparability-invariant backtest window.
• Established a shared-contract seam (Zod schemas) pinning every backend/frontend/SDK response shape to eliminate drift across the stack.
• Built the full React/TypeScript frontend: strategy builder (condition-tree editor), interactive candlestick charts, and a significance-first strategy leaderboard.
• Shipped programmatic-SEO public result pages (DB-free static snapshots) as the primary organic-growth channel.
• Delivered supporting surfaces: an SDK, a CLI, and an MCP server, all sharing one contract layer.
• Set up and ran production infrastructure: Vercel-hosted frontend, Dockerized backend on a VPS, GHCR image pipeline, and one-command deploy tooling.
• Integrated Stripe billing for freemium tier enforcement and subscription upgrades.
• Built live WebSocket market-data ingestion from Binance with reconnection/failover handling.
