Experience
London-based work on a luxury travel and hospitality stack (AXLEMS): Node/Express microservices, React clients, GDS and payments, AI-assisted booking flows, and production operations, including AWS CodeBuild and S3 static deploys for React apps, CodeDeploy/appspec-driven releases on EC2, SES, and PM2/Nginx. In a lean team, contributed across the delivery lifecycle: requirements and business rules, scope and prioritization, solution design for booking and payments, quality assurance on complex scenarios, hands-on ownership of integrations (Sabre, Stripe, and related APIs), technical documentation, and support for stable releases and production operations.
Backend repos include dedicated services (e.g. user, booking, assistant, admin-controls) with Express, MongoDB, Passport/JWT, Winston logging, and AWS SDK (S3). User flows use AWS SES for transactional mail (including OTP and receipts), Stripe for customers and payment methods, Revolut and PayHere payment gateways where the business requires them alongside Stripe, scheduled jobs such as Stripe FX refresh, and the main React `user-booking-service` (Stripe Elements). The booking stack also integrates Sabre and Amadeus, Redis caching, and LangChain/OpenAI-style automation where the booking service uses it. Frontend monorepo adds internal micro-apps (admin dashboard, user login, booking, manager control), Tailwind, and a separate `career-portal-service` (Vite/React). Customer-facing areas include travel-advisor pages, webinars, and content/SEO-style pages, not only checkout.

Stack includes Express/Mongoose, Vite/React, Tailwind and Ant Design, Stripe.js / React Stripe.js, and LangChain/OpenAI elsewhere in the same backend where the product uses them.
