Open to remote roles and freelance projects

I build the systems behind sales teams: CRM data, outbound and AI automation.

I'm Moizam Hussain, a GTM Engineer based in Pakistan working remotely. I run HubSpot, build the data pipelines that keep it clean, and automate the repetitive work with n8n and AI agents. Before this I spent years in data engineering and leading QA teams, so I care about things working reliably, not just in a demo.

What I can do for you

Services

The work I take on most often. If your problem sits somewhere between your CRM, your data and your outreach, I can probably help.

HubSpot setup and RevOps

Admin, permissions, pipelines, lead routing, data cleanup, dashboards and written SOPs so your team actually follows the process.

AI agents and n8n automation

WhatsApp and voice agents, RAG assistants grounded in your own content, lead scoring and workflow automation with n8n, Make.com and GoHighLevel.

Data pipelines and reporting

Sync your CRM and tools into Postgres or Snowflake, model the data, and give the team dashboards and daily reports they can trust.

Lead generation and outbound

Prospect lists from Apollo and Clay, enrichment and AI classification, then email and LinkedIn campaigns through Smartlead and Walead.

Projects

A few things I've built recently. Client details are shared only where I have permission.

GTM Engineering

Sales data platform for a B2B sales team

A self-hosted warehouse and service layer so the sales org has one reliable view of its HubSpot and Smartlead data.

  • Nightly syncs of HubSpot objects and associations plus Smartlead campaigns into Postgres, with per-run logging and 27 tracked migrations
  • FastAPI service that matches leads to master records and stops HubSpot, Clay, Apollo and manual edits from overwriting each other
  • Metabase dashboards and a daily rep KPI image posted to Google Chat every weekday morning

An assistant for "Viaja con Alvaro" that answers customers using only the agency's own content.

  • Website content scraped into a Qdrant vector database so answers stay grounded
  • Extended to WhatsApp, Instagram and Facebook with a follow-up sequence
  • Human handoff when a real person needs to step in
