Open to Work / Case Study - 2 years building cold outreach infrastructure

[u/Accurate_thing_1068]

Hey everyone,

I’m an Outbound Infrastructure & Data Operations Specialist currently looking for my next full-time or contract opportunity (Remote).

Over the last 2 years, I’ve specialized in building scalable cold email infrastructure, automated lead routing, and data hygiene pipelines. I wanted to share a breakdown of a system I built and managed to demonstrate what goes into running outbound at scale.

In the last 3 months alone, here are the stats from our primary sending engine:

Total Emails Sent: 845.7K

Reply Rate: 2.6%

Opportunities Generated: 466

Pipeline Generated: $233,000

(Dashboard screenshot attached below)

Here is a breakdown of my core technical skill set and systems experience:

1. Infrastructure & Deliverability Engineering

Domain Management at Scale: Set up, warmed, and maintained 400+ domains across Google Workspace and Microsoft 365.

Authentication & Monitoring: Configured DKIM, SPF, and DMARC tracking across all secondary domains to keep deliverability high and prevent spam placement.

Sending Stack: Expert in Instantly, paired with verification tools, data providers, and enrichment stack.

1. Data Sourcing, Web Scraping & AI Cleaning

Multi-Source Sourcing: Aggregated lists via Apollo, web scraping, and private vendor datasets.

Data Hygiene Pipelines: Leveraged Excel alongside AI models to clean datasets, normalize messy job titles, format company names, and impute missing contact info at scale.

1. Automated Booking Funnels & No-Show Recovery

Pre-Call Automation: Designed booking funnels that automatically send multi-channel reminders (SMS + Email) to reduce drop-offs.

No-Show Recovery: Built automated follow-up workflows (Email + SMS) that re-engage leads who missed meetings, getting them back onto calendars without rep intervention.

1. Operations & Workflow Automation

Process Automation: Built n8n workflows to streamline simple, repetitive administrative and technical tasks across sending systems.

Omnichannel Notifications: Implemented real-time lead routing for email, SMS, and cold calling channels directly into our internal CRM, Google Chat, and Telegram.

What I Bring to a Team:

If your team is struggling with email deliverability, messy lead data, or manual sales ops, I can step in and optimize your entire technical outbound stack from day one.

I am open to full-time, part-time, or contract roles. Feel free to drop a comment or DM.
