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.
Extended and enhanced a PHP-based clinic CMS — new features, database schema restructuring, bug resolution, and overall performance improvements. Integrated blockchain and NFT functionality, implemented NFT minting flows, and connected the blockchain layer to a React frontend covering wallet connections and on-chain interactions. Delivered 10+ feature extensions across the full stack.
Led the launch of two customer-engagement platforms, directly contributing to improved user retention metrics. Engineered an automated JavaScript chatbot that reduced average response time by 40%. Delivered 100% of sprint tasks on time across a fast-paced 3-month contract.
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.
Full-featured web analytics platform (tongji-tj.com) built with Laravel 11. Domain ranking engine, visitor tracking, wildcard domain support, Redis-backed caching, and cron-powered data pipelines. Currently live and serving real traffic.
PHP CLI tool that syncs large MySQL datasets into Redis with chunked queries to prevent memory exhaustion. Built for a ThinkPHP application serving high-concurrency reads. Handles millions of rows with configurable batch sizes.
23 public repositories spanning backend utilities, API integrations, web scrapers, automation scripts, and experiments in Web3. Always building, always shipping.
I'm actively targeting Senior Software Engineer roles at top-tier companies. If you're building something ambitious — scalable APIs, distributed systems, or blockchain-native products — I want to hear from you.
