Core area
Frontend
React and Next.js for interfaces that stay clean, maintainable, and fast enough without overengineering.
Profile
Engineer for products, backends, and operations.
I build software end to end: interfaces, APIs, deployment paths, and the infrastructure behind them. My working style is practical and operations-aware, with a strong bias toward clear code and systems that remain understandable over time.

안녕하세요. 제품 개발과 인프라 운영을 함께 다루는 엔지니어 허련호입니다.
Core area
Backend
Node.js and Go for APIs, service integration, and server-side logic that remains easy to operate.
Core area
Infrastructure
AWS, Linux, Docker, Kubernetes, nginx, and HAProxy for delivery pipelines and production systems.
Core area
Data
Python-based concurrent processing for workloads ranging from large batch jobs to massive record handling.
How I work
Generalist execution with infrastructure depth.
I am most effective where application development and operations overlap. That includes building user-facing products, designing backend services, and making sure deployment and runtime environments stay stable. I have also worked with Java, C, Perl, and PHP, which helps when existing systems need to be understood rather than replaced.
Scale and systems
Comfortable with cloud and self-managed environments.
I have managed AWS infrastructure and bare Linux servers directly, including networking, deployment, and gateway configuration. In personal environments, I run home servers for mail, web, development, and other services, connected through VPN and VXLAN with an external AWS instance as the public entry point.
Principles
What I optimize for.
- Readable code is a feature.
- Infrastructure should reduce operational stress, not increase it.
- Fast delivery only matters if the result stays maintainable.
- A smaller system that is well understood usually wins.
Experience summary
Relevant strengths.
I can move from product code to runtime concerns without changing context: frontend UX, backend APIs, containers, CI/CD, proxies, load balancing, and infrastructure troubleshooting. That range is useful when a project needs momentum without handoff friction.
I also have strong practical experience with Python-based concurrent data processing over very large datasets, where operational reliability matters as much as raw throughput.
