// 01 :: Capabilities

[GDS]

GDS Integration

Search, pricing, and booking against Amadeus, Sabre, and Travelport, the classic global distribution systems that power airline inventory.

[NDC]

NDC & LCC Distribution

IATA NDC implementations and direct low-cost-carrier connections, covering the full order lifecycle from offer to servicing.

[PAY]

Payment Gateways

Wiring gateways such as CyberSource into booking flows: authorization, capture, multi-currency handling, and failure recovery.

[API]

API Engineering

REST and SOAP integrations with third-party systems: authentication, idempotent order handling, and versioned contracts.

[STACK]

Full-Stack TypeScript

Node.js and Bun services with Hono, Next.js frontends, PostgreSQL and Redis, from schema to UI.

[OPS]

Reliability & Observability

Rate limiting, circuit breakers, retries with backoff, OpenTelemetry tracing, and Prometheus metrics, so bookings don't fail quietly.

Ticketmet Live

ticketmet.com

An online travel agency for searching, pricing, and booking flights, running in production. I built and operate the platform end to end: GDS-backed search, booking management, and integrated payments. The platform code lives in private repositories.

Built for production use with OAuth2 token management, circuit breaker, Redis-backed distributed rate limiting, retry with exponential backoff, HMAC-validated webhooks, OpenTelemetry tracing, Prometheus metrics, TypeScript declarations, a CLI, and a zero-dependency mock adapter for testing.

// 04 :: About

I work in travel technology, building the systems that search, price, and book flights. That means integrating GDS platforms (Amadeus, Sabre, Travelport), implementing IATA NDC, connecting low-cost carriers, and wiring payment gateways such as CyberSource into booking flows.

Day to day that's API engineering: REST and SOAP integrations, authentication, idempotent order handling, and the operational concerns (rate limits, retries, observability) that keep bookings from failing quietly.

Outside the airline domain I build full-stack TypeScript systems: my zerotrust starter covers authentication (OAuth, passkeys, MFA), multi-tenant organizations, billing, and the security hardening that production SaaS needs.
