At Ernst & Young LLP, I lead backend development for group overseas and retail travel insurance products, taking delivery from requirements and Jira ticket analysis through production release.
I designed and built Node.js microservices and RESTful APIs, and integrated the BillDesk payment gateway to improve transaction reliability and reduce payment failures. I also hardened payment modules with logging, error handling, and transaction validation.
I built OCR services that automated verification of cheques and ID proofs, replacing manual document checks. I optimize backend code, algorithms, and data access to maintain performance under high transaction volumes.
At FunctionUp, I built Node.js and Express.js applications with MongoDB and MySQL, used Redis caching, and worked on file migration between Google Cloud Storage and Azure Blob Storage. I’m Triplebyte Certified in Backend Engineering (Node.js) and AWS Certified Cloud Practitioner.
