Full-stack product engineering

Full-stack features in the data, workflows and virtual-lab sections of the platform: data browsing and filtering, project and lab management, simulation launch and results, credits. Each shipped from FastAPI endpoint and schema to React screen and end-to-end test.

Around 90% of the new React/TypeScript interface, with server-state caching and invalidation, normalized client stores, memoized render paths and virtualized lists for data-heavy views.

Backend and UI migration of a legacy application to a modular core, screen by screen and service by service, without freezing feature work.

A systematic refactor: module boundaries, shared components, strict typing and lint rules that keep the codebase from drifting back.

Patient, appointment and billing workflows built from database schema and REST endpoints to the screens clinic staff use every day.

Forms, tables, scheduling and date components shared by every module, so the product looked and behaved the same everywhere.

HTTP and CDN caching, code-splitting, lazy loading and lighter rendering made the landing page about twice as fast.

React Native and Expo apps for iOS and Android from one TypeScript codebase, with a shared component library and typed API clients. Client apps included Juice Plus+, Kudos and Fimimus.
