ABOUT
EREFY
Tech Lead / Full-stack Engineer
I'm a web engineer with over 12 years of experience, ranging from contract development to building and operating large-scale web services. Most recently, I led a three-year initiative to migrate our company's product infrastructure to the cloud, while modernizing our development environment and driving the adoption of AI across the engineering organization. My guiding theme is simple: accelerate a service's growth through technology. I draw on backend, infrastructure, and AI as whatever the problem calls for, with a single goal — maximizing how fast both the product and the team behind it can grow.
SKILL
A full-stack engineer with a backend foundation, working across infrastructure and frontend alike. I care deeply about scalable architecture and a great developer experience.

HISTORY
Led a three-year migration of the service's infrastructure from on-premises to AWS. Built out CI/CD and observability to elevate the developer experience, and more recently have been driving AI adoption across the division.
Maintained and developed a company-review platform, balancing the repayment of technical debt with new feature work to support the service's long-term growth.
Delivered a wide range of web systems and apps on contract — social networks, e-commerce, e-learning, and social games. Later led a PHP-to-Rails migration and the introduction of Docker.
CAREER
More than pure technical curiosity, my consistent thread has been solving real problems and turning solutions into systems.
What I aim to be: an engineer who accelerates a service's growth through technology. I keep a strong footing in proven, standard technologies (Rails / AWS) while investing early in emerging areas like AI agents.
- Strengths — Fast learner / problem solver / strong sense of ownership

FAVORITES
I'm a fan of light novels, anime, and cheering on VTubers. Lately I've been enjoying personal projects built around a VSinger I'm rooting for.
