I have over 5 years of experience in software development, focusing on building robust and scalable solutions that drive value across various industries. My expertise lies in designing and maintaining high-load distributed systems, where performance, reliability, and fault tolerance are essential under intense workloads. I emphasize creating architectures that are not only scalable and flexible but also easy to support and evolve over time. I always strive to deliver high-quality results that align with both user expectations and business goals.
Throughout my career, I’ve worked in large technology companies known for their rigorous standards, which helped me develop a strategic mindset and the ability to craft long-lasting, efficient solutions. In addition to back-end development, I have hands-on experience in front-end technologies, allowing me to approach projects from a full-stack perspective.
I enjoy sharing knowledge and best practices, which is why I actively maintain and develop a technical blog. It serves as a platform to document insights, explore new technologies, and contribute to the developer community.
I thrive in team environments, adapt quickly to new settings, and am committed to mastering tools and technologies to achieve the best possible outcomes. When entrusted with a task, I take full ownership and ensure timely delivery with high efficiency and quality, regardless of the project’s scope or audience.

- Added loading and indexing of multiple CTR-model versions from GCS, enabling side-by-side comparison and switching within experiments without redeploys.
- Delivered a centralized configuration system tunable per A/B experiment group for rapid hypothesis testing.
- Rebuilt the category tree as a facet-based structure with counters and facet logic.
- Diagnosed an ElasticSearch performance bottleneck in JSON deserialization within the ES client and evaluated a custom marshaller.
- Developed a delivery orchestrator and a state-tracking tool for observability.
- Adopted AI-assisted development tooling (Cursor, Claude Code, GitHub Spec Kit, OpenCode, MCP) to speed up prototyping, spec-driven workflows, and delivery.
- Deepened expertise in large-scale search, ranking, and recommendation systems on ElasticSearch.
