I work on systems where uptime and data quality matter, and I build software that helps stakeholders understand operational data and make decisions.

- Coordinate scope and timelines with stakeholders and external partners
- Backend/Data: Java (Spring Boot), Python, PostgreSQL (time-series), SQL, REST APIs

- Practices: layered architecture, validation/error handling, Git workflows, clear documentation
- Tools: Jira, Figma (flows/wireframes)
