About
I joined Themis as an early engineer to build a multi-tenant GRC (governance, risk, and compliance) platform for regulated industries. I owned interactive UIs for core modules, a reusable themed component library (Mantine, Ag-Grid, ECharts, Storybook), and backend APIs with Node.js, Ruby on Rails, and PostgreSQL—including audit trails, document versioning, and fine-grained RBAC for 40+ enterprise clients. I also integrated LLM providers for document summarization and issue classification, and Stripe for subscription billing on GCP with Docker-based CI/CD.
Highlights
- Core modules & performance: Built experiences that reduced onboarding time and UI load times measurably, using React, Next.js, Redux, TanStack Query, and a documented component library shared across products.
- Dense data UI & reuse: Shipped complex tables and dashboards with Ag-Grid and Apache ECharts, cutting frontend development time through reuse and Storybook-driven workflows.
- Enterprise tenancy & compliance: Implemented REST APIs and RBAC with audit trails, escalation, and document versioning for dozens of enterprise tenants.
- AI-assisted workflows & billing: Integrated OpenAI and Anthropic via Node middleware for regulatory document workflows, and Stripe for tiered SaaS billing.
