Engineering the Systems That Move the World.
Head of Engineering specializing in multi-supplier travel aggregation, native mobile engines, and resilient distributed backends. Below is the live aggregation topology powering sub-100ms fare search.
High-concurrency ingestion gateway polling and streaming raw flight, hotel, and transit schedules from legacy XML/SOAP and modern JSON NDC APIs.
The central brain: Normalizes disparate supplier data into canonical FlightOffer and SeatManifest DTOs, applies markup rules, and validates availability.
Guarantees zero-collision atomic seat reservation with automatic 10-minute lease TTLs, webhook delivery retries, and high-frequency IoT telematics.
Multi-tenant white-label portals for travel agencies and public B2C booking engines featuring instant ticketing, automated invoicing, and credit limits.
High-performance native mobile apps delivering 60fps booking experiences, offline boarding pass storage, real-time push flight status notifications, and biometric payments.
Travel Technology, Engineered End-to-End
Direct GDS/NDC airline connectivity, legacy XML/SOAP normalizers, sub-millisecond seat leasing, and multi-tenant transit booking architectures.
Full-Lifecycle OTA Booking Engines
Engineered high-conversion B2C flight & hotel booking portals and multi-tier B2B agent distribution networks with instant PNR issuance and automated ticket re-issuance.

}Client View vs. Engine Room
Peel back clean white-label operator interfaces to inspect underlying PostgreSQL 16 DDL schemas, Redis worker pipelines, Pest 4 concurrency suites, and sub-millisecond benchmarks.
Normalizes Amadeus, Sabre, and airline NDC into one unified API, preventing price discrepancies and stale seat holds.
Multi-Supplier Travel Aggregator & OTA Platform
Enterprise flight & hotel aggregator unifying 12+ GDS, NDC, and XML/SOAP supplier feeds into a high-speed OTA booking engine with dynamic pricing, agent credit lines, and sub-100ms fare search.

System Lifecycle Workflow
Industrial Performance & Load Telemetry
Empirical telemetry benchmarks demonstrating throughput multipliers, memory reduction, and zero-loss seat lock acquisition.
Measured during parallel 12-supplier GDS/NDC search fan-out on 8 vCPU instance.
Cold framework boot avoided via resident memory lifecycle in Swoole/Octane.
Shared memory tables and connection pool reuse across concurrent requests.
Atomic Redis Lua script execution vs row-level database locking contention.
Interactive Load & Telemetry Simulator
Adjust synthetic load parameters to observe real-time latency curve reactions.

Core Architectural Principles & Engineering Invariants
Database queries and cache namespaces are hard-isolated per tenant via automated search-path injection and static Pest architecture rules.
Every booking and financial transaction requires balanced debit and credit legs (Σ Debits == Σ Credits), preventing silent financial drift.
High-concurrency airline and bus seats are locked using single-thread Lua scripts with self-expiring leases, preventing race-condition double bookings.
Flutter mobile applications maintain encrypted local SQLite databases with optimistic updates and background WebSocket reconciliation.
