Backend Developer / Security Enthusiast / System Architect
01 / About
Hi, I'm Alex Chen — a backend-focused software engineer with a deep passion for system architecture, performance optimization, and building secure, scalable infrastructure.
I specialize in designing and implementing distributed systems that handle high-concurrency workloads, with a strong interest in application security and data protection. I believe that great software is both elegant and resilient.
Over the past 5 years, I've worked across fintech, cloud infrastructure, and developer tooling domains — shipping production systems that serve millions of requests daily.
When I'm not writing code, I'm exploring cryptography papers, contributing to open-source security tools, or breaking things in CTF competitions.

A high-performance data management platform with end-to-end encryption, fine-grained access control, and real-time audit logging. Handles 50K+ requests/sec with sub-5ms P99 latency.
A fault-tolerant message broker built from scratch with leader election, log replication, and exactly-once delivery semantics. Inspired by Raft consensus algorithm.
A CLI toolchain for scaffolding, deploying, and monitoring cloud-native microservices. Generates Helm charts, CI/CD pipelines, and observability dashboards automatically.
04 / Contact
I'm currently open to full-time roles, contract work, and interesting collaborations. Whether you have a project in mind or just want to talk systems — my inbox is open.
