Work Experience
Backend Developer
Clean90
Present - Present
Architected a habit-tracking REST API in Node.js/Express with strict layered MVC (routes → middleware → controller → service → repository), designed across ~10 design docs before implementation. Enforced data integrity with a partial-unique index so a user can never hold two active runs; split validation into Zod shape checks (400) and controller state checks (409/403). Secured every protected route with JWT auth middleware (header tokens, mobile-ready); documented leaderboard N+1 fixes, batched nightly rollover, and a SQLite → PostgreSQL migration path.
Auth & User Service Developer
Pizza App Backend
Present - Present
Built a MongoDB/Mongoose REST backend with cookie-based JWT sessions and bcrypt password hashing via a Mongoose pre-save hook—plaintext passwords are never stored. Standardized a consistent JSON response envelope ({ success, message, data, error }) and centralized server/DB configuration so environment variables are read in one place.
React SPA Developer
Pokémon Explorer
Present - Present
Built a component-based React single-page app that fetches and renders data from a public REST API, managing shared state across components with the Context API.
