At Paydock, I built and maintained TypeScript and React features for a payment orchestration platform. I implemented payment flows for authorisations, refunds, subscriptions, webhooks, and idempotency, and led Visa and Mastercard network tokenisation from merchant onboarding through cryptogram generation.
At SigbotAI, I defined, designed, and shipped the core product logic for an AI-powered SaaS platform. I built its React frontend and RESTful APIs, integrating the ChatGPT API for business workflow automation and the Binance API for trading account connectivity.
At Tafaxtra, I built a cryptocurrency payment system for on-chain transactions. I addressed concurrent transaction updates with database-level locking and idempotent design, then rebranded the product to SigbotAI and migrated its web application from Nuxt.js to React.js.
At FXCore100, I designed and built a full-stack trading and analytics platform, and deployed a crypto technical analysis platform covering charting, signal logic, and data pipelines. My project work also includes a multi-exchange arbitrage engine and an AI-enhanced futures trading system.
