Fullstack Engineer · Database Infrastructure Specialist · Data Engineering Practitioner
I build scalable applications, database platforms, internal tools, and data pipelines for fintech, infrastructure, and enterprise systems.
I am a Fullstack Engineer and Database Infrastructure Specialist with 5+ years of experience building, maintaining, and optimizing systems in fintech and enterprise environments.
My work focuses on:
- Building backend systems, APIs, fullstack dashboards, and internal platforms
- Managing PostgreSQL, Oracle, SQL Server, MySQL/MariaDB, Redis, and large-scale database operations
- Designing data pipelines, CDC streaming, and database migration workflows
- Operating infrastructure across AWS, Alibaba Cloud, on-premise servers, Linux, Nginx, Apache, Caddy, Docker/Podman
- Improving system reliability through monitoring, performance tuning, backup/restore, and security hardening
Previously, I helped build and operate fintech data center infrastructure, including data warehouse systems, internal networks, database operations, and compliance-oriented environments such as ISO 27001 and UU PDP.
I enjoy building practical systems from scratch, especially tools that reduce manual work, simplify database access, and avoid unnecessary vendor lock-in.
