I help businesses transition from complex, legacy systems to cost-effective Cloud Native Architectures. Specializing in high-performance inventory systems and serverless migration strategies that reduce operational overhead.
Core Competencies
Leading OTA Competitor • Early Phase
Joined as a trainee and rapidly took ownership of the guest-facing platform. Initially focused on feature delivery using React, Node.js, and MySQL.
The Bottleneck
The initial monolithic architecture struggled. We attempted to solve this with complex custom solutions:C++logic layers and self-managedKafka/StarRockspipelines.
Result: High operational costs & maintenance difficulty.
Leading OTA Competitor • Present Role
Pivot strategy from "building from scratch" to "managed cloud integration." Redesigned the entire data pipeline to prioritize maintainability, cost-efficiency, and developer experience.
Modernization Strategy
Self-Hosted Kafka → AWS Kinesis & EventBridge
Data Engineering
Managed CDC Pipelines (DMS) & Bit-Packed Caching
Business Impact:
Eliminated the need for specialized C++ engineers, reducing hiring costs. Lowered infrastructure costs by moving to serverless event scheduling and managed services.
Legacy → Managed Services
Retired a complex self-hosted Kafka/StarRocks pipeline. Architected a serverless CDC solution using AWS DMS and Kinesis, reducing operational maintenance by 60% while maintaining data integrity.
Lower TCO & High Reliability
AWS DMS • Kinesis • Lambda
High-Speed Suggestion Engine
Developed a low-latency room combination and suggestion algorithm in C++ using the Crow framework. Optimized heavy computation tasks that were previously bottlenecking the Node.js event loop.
Sub-millisecond Processing
C++ • Crow Framework • Algorithms
Serverless Inventory Hold
Engineered a fail-safe booking system using EventBridge Scheduler and SQS. Prevented overbooking and race conditions by decoupling inventory release logic from the main application flow.
