Status: Available for work

Backend Developer building secure Node.js + Express APIs with MongoDB, focused on robust authentication and scalable data access.

01—About

Crafting APIs that feel like invisible scaffolding keeps me awake at night. I thrive when a single line of code can secure a user’s data and scale with traffic without breaking a sweat.

Every day I dive into Node.js, Express, and MongoDB, wiring microservices that power real‑time dashboards for logistics firms. I design RESTful endpoints that validate payloads with Joi, enforce JWT authentication, and log every request to Elastic for audit trails. NestJS is my new playground—its modular architecture lets me layer caching with Redis and orchestrate background jobs in BullMQ, all while keeping the codebase testable with Jest. I obsess over readability, write comprehensive integration tests, and refactor legacy routes into clean, type‑safe controllers.
