At Ninja Van, I built a Gemini Flash-based email-to-case workflow using Kafka, Express.js, and TiDB. Intent-coverage thresholds and human fallback helped reduce customer escalations by 76%.
As service owner for Notifications, I designed and launched SMS provider routing based on shipper and template rules. I also designed a Hazelcast-backed configuration layer for serving country-level configurations and maintaining defaults during cache or database failures.
At PayMongo, I contributed reusable adapter interfaces and documentation for payment-provider integrations, reducing integration and testing time from more than three months to approximately three weeks. I also migrated performance-critical workloads from Ruby on Rails to Go; Datadog APM validated a 28% reduction in p95 latency and a 31% increase in throughput.
At Hitachi Vantara, I implemented the migration of a React monolith into five independently deployable Module Federation domains. I also helped reduce frontend build and deployment time from approximately 20 minutes to 10 minutes by migrating Webpack to Vite and introducing multi-stage Docker builds.
