Built and shipped the Saga iOS app and an Expo/React Native version on her own. Designed an anonymous-first identity model using Supabase and integrated Sign in with Apple. Implemented RevenueCat subscriptions with a paywall driven by live App Store pricing and connected accounts through Supabase with Apple authentication. Developed a multilingual content pipeline in English, Spanish, and Portuguese using Contentful, including localization management. Passed Apple review and shipped the app to the App Store.

Built and shipped Synth Dashboard, a Next.js subscription analytics platform for crypto market data (volatility, options pricing, liquidity analytics, liquidations, and prediction markets). Developed Synth Terminal powered by the Anthropic SDK with multi-turn tool use, SSE streaming, sandboxed code execution (E2B), file attachments, and per-generation cost tracking. Owned an end-to-end Stripe billing pipeline synchronized to Supabase in real time across tiered subscription plans, and integrated Web3 wallet connectivity (wagmi). Delivered crypto data visualization dashboards using ECharts over Synth API and multiple market data feeds (Deribit, Polymarket, Limitless). Added GA4 conversion tracking via Measurement Protocol and PostHog, including AI cost telemetry. Improved agent efficiency by adding prompt caching and switching wiki tooling to keyword-filtered retrieval with token-usage logging.

Led technical interview loops and contributed to technical and UX decision-making. Built client dashboards, an admin panel for workers, and a mobile application in parallel. Owned the KYC flow end-to-end and successfully released it to production. Worked across web and mobile surfaces with testing and continuous delivery practices.
