Jie-Ting Jiang
Senior Software Engineer specializing in data-intensive applications. I transform complex datasets into intuitive tools, backed by 6+ years of building large-scale BI systems and 3D visualization platforms. From Python / Django-powered APIs to SvelteKit / React / Next.js with Three.js / D3.js frontends, I architect end-to-end solutions that empower 30+ departments to make data-driven decisions. Currently focused on the intersection of AI-assisted engineering and high-performance data visualization.
Experience
Frontend Engineer
Pay Web Dev, Line Pay
Cross-Framework Migration & AI Tooling
- Led full migration of the Insurance Platform from SvelteKit to Next.js; designed AI-powered code review workflows and spec-driven development processes that cut estimated migration effort by ~70%.
- Introduced AI-assisted development practices (agents, MCPs, prompt workflows) across the engineering team, reducing repetitive tasks and accelerating feature delivery.
Line Pay Finance Platform
- Modernize and maintain the Finance Platform, improving long-term stability, performance, and developer experience across the stack.
Senior Business Intelligence Engineer
Data Office, Gogoro
Business Intelligence Platform & Data Visualization
- Built and scaled a BI platform adopted by 30+ departments, making decision science accessible org-wide — from self-serve dashboards to advanced exploratory tools.
- Designed a 3D customer exploration tool (Three.js + Svelte) for querying and visualizing 1M+ records, optimized to run smoothly on average hardware; built a parallel asset management app for 1M+ battery assets.
Platform & Developer Experience
- Designed a standardized API framework for data-intensive applications with data engineers, enabling rapid development of exploratory analysis and decision science tools.
- Built shared component libraries (UI, charts, maps) in React and Svelte with designers, accelerating app development and ensuring visual consistency across the platform.
Data Visualization Engineer
Network Excellence, Gogoro Network
Executive Dashboards & Geospatial Analysis
- Built full-stack visualization solutions for executives to monitor 2,500+ GoStations with regional and temporal drill-downs (daily/weekly/monthly).
- Developed an automated geospatial analysis tool with data analysts that cut GoStation site assessment from days to seconds — a 95% reduction in decision turnaround.
Architecture Modernization
- Rearchitected a monolithic decision support system into Python-based APIs and microservices, enabling data scientists to ship business logic directly without translation delays — improving debugging, testing, and deployment flexibility.
