Work History

  1. Senior Software Engineer

    Anoc99 / Cloud Wind · Vietnam (Remote)

    Lead backend engineer for Node.js/NestJS microservices handling 50k–100k+ requests per month. Tracked down a long-standing latency issue — root cause was slow queries and missing cache layers — resolving both for a 30% performance improvement. Managed AWS infrastructure (EC2, RDS, S3, IAM) with CloudWatch alerting, achieving 99.9% uptime and ~25% reduction in incident response time. Replaced manual deployments with Docker + GitHub Actions CI/CD, cutting release cycles by 70%. Mentored 2 junior developers to shipping features independently.

BlockLease

A full-stack platform for tamper-proof document authentication on the Polygon blockchain. Documents are uploaded, hashed, and anchored on-chain to produce cryptographic proof of authenticity. Solidity smart contracts handle on-chain verification; Node.js backend manages hashing logic; React frontend supports document upload, verification status workflows, and role-based dashboards. Deployed on AWS with Git-based CI/CD — every push to main triggers automatic production deployment.
