B2B and prosumer SaaS startups optimizing self-serve signup-to-activation funnels, interactive onboarding checklists, and product analytics frequently search to hire a freelance Product-Led Growth (PLG), PostHog, Amplitude, Segment & onboarding engineering programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and Growth Engineer available via Upwork.

Core Product-Led Growth & Activation Engineering Capabilities

  • Frictionless Signup & Time-to-Value Onboarding: Building magic-link / Google / GitHub / Passkey 1-click signups, interactive sample-data sandboxes, and stateful progress checklists in React and Next.js.
  • Type-Safe Event Taxonomy (PostHog, Amplitude, Mixpanel, RudderStack): Enforcing strongly typed analytics schemas across frontend and backend so funnel conversion, cohort retention, and feature adoption dashboards are 100% trustworthy.
  • Viral Loops, Team Invites & Referral Programs: Engineering workspace collaboration invites, public shareable artifact links (like Loom/Figma/Notion), and double-sided Stripe credit referral rewards.

Frequently Asked Questions

Why do ad-blockers break client-side PostHog or Amplitude tracking, and how do you fix it?

Privacy extensions block direct requests to `posthog.com` or `amplitude.com`. I configure a first-party Next.js / Cloudflare Worker reverse proxy (`/ingest/*`) paired with server-side milestone events so 100% of funnel conversions are captured accurately.
