01ESG Dashboard module — built end-to-end
Designed and shipped the dashboard module from scratch across Next.js + tRPC + Prisma + PostgreSQL. Interactive Environment / Social / Governance views, Executive variants, and drill-down supplier analytics powering daily workflows for sustainability officers.
02Report workflow: ~30–40s → under 1s
The core report workflow was the heaviest on the platform. I split one over-fetching API into targeted endpoints, added indexed access paths, and virtualized + progressively rendered the frontend — bringing render time from ~30–40s down to under 1s.
03AI-automated dev workflow — Claude Code skills & agents
Built custom Claude Code skills and AI agents that automate the team's ticket-to-PR workflow — planning, implementation scaffolding, Cypress E2E test generation, and automated PR review.
04Reusable component library — 15+ pages
Architected a responsive, type-safe component library that became the foundation of the product UI revamp, enforcing visual consistency and accelerating downstream feature delivery.
05Automated PDF + email pipeline
Cron job + server-side PDF generation + email delivery, replacing manual weekly exports across every customer tenant.
06Scope 3 emissions — new categories & ingestion
Extended the Scope 3 emissions module with new Fuel & Energy (C3) and Waste (C5) categories — building the data model, calculation logic, and bulk-upload ingestion pipelines for historical data.
