01 / Motivation

Professional communities need one place to meet, share content, follow events and stay notified — without the product feeling heavy.

02 / Solution

A platform spanning communities, events, content and subscriptions, built on a Next.js frontend and NestJS + PostgreSQL backend.

03 / My contributions

05 / Decisions & challenges

List virtualisation and infinite pagination to keep large feeds fast.
Layered security: JWT auth, API rate limiting, reCAPTCHA, honeypots and CSP, plus AWS WAF, Shield and CloudFront with DevOps.
Skeleton states, lazy loading and Zod validation; accessibility improved through Lighthouse audits.

06 / Learning

Working across this breadth taught me how features interact — a notification, a comment and a subscription all touch the same system.
