GTM Engineer  ·  carries a quota & ships the systems

I build the go-to-market machine,
then I run it.

Most people do one side. I lead a quota-carrying sales team by day and engineer the data platforms, prospecting engines, and AI automations that make it move. Same hands on both.

The rare full-stack GTM person

GTM Engineering usually means hiring two people and hoping they talk. I'm the seam between them: I know what a rep actually needs on a call because I coach seven of them, and I can build the system that delivers it because I ship code.

Sells

I've lived the number

District sales leader in restaurant tech. Pipeline, forecasting, territory design, Sandler coaching, enablement. I build for GTM because I *am* the GTM user — I know where deals stall and where reps waste hours.

Ships

I've built the tooling

Python data pipelines, web apps deployed to Cloudflare/Vercel, CRM automation over live APIs, LLM agents, and self-hosted infrastructure. Not prototypes — systems my team depends on every morning.

Selected work

A sample of GTM systems I've designed, built, and operated. Live tools carry proprietary data, so these describe what they do and the outcome rather than exposing internal dashboards — happy to walk through any of them live. draft — swap in your exact metrics

Revenue Intelligence Dashboard

Sells · Ships

Pulls Salesforce, Salesloft, and Sigma every morning, reconciles them, and renders a live team scoreboard — pacing, forecast lock/stretch, and per-rep activity — deployed as a web app the whole team opens daily.

Replaced hours of manual reporting with a one-command refresh.

Prospecting & Enrichment Engine

Sells

Takes a rep's raw territory and enriches every account: detects the incumbent tech stack via HTML fingerprinting, checks delivery-marketplace and ads presence, and generates a prioritized, talk-track-ready outreach brief per target.

Self-sourced research that converts directly into booked revenue.

AI Sales-Ops Skill Suite

Sells · Ships

40+ automations that run a sales manager's week: 1:1 prep, forecast roll-ups, deal inspection, call grading against a coaching framework, coaching plans, and monthly business reviews — built on Claude with data + CRM connectors.

Turned recurring manager busywork into repeatable, one-command workflows.

Win-Signal Data Lake & Auto-Researcher

Ships

Unifies graded call transcripts, activity data, and outcomes, then runs an automated hypothesis engine that surfaces which behaviors actually correlate with closed-won — a living "what works" memo instead of gut feel.

Coaching decisions grounded in the team's own data.

CRM Engineering (Pipedrive)

Sells · Ships

Schema-driven CRM build for an outside client: provisioned custom fields, pipelines, and stages over the REST API, audited and de-duplicated live data, and wired automation — all stage-gated and read-only-first for safety.

A clean, automated CRM stood up from a versioned schema.

Self-Hosted Platform & Infra

Ships

Runs the whole operation on owned infrastructure: a Proxmox cluster, reverse-proxied services with SSO, scheduled jobs, and multiple domains deployed via CI — the backbone the GTM tools sit on.

Full-stack ownership from metal to deployed app.

How I work

// ship close to the user

Build for the rep on the call

I coach the people the system serves, so I build for the real workflow, not the theoretical one. Fast feedback loop from problem to running tool.

// data over gut

Instrument everything

If a decision matters, it gets a number behind it. I turn scattered signals into dashboards and correlation studies the team can act on.

// safe by default

Read-only first, then automate

Live revenue systems deserve care. I audit and dry-run before I write, stage-gate risky changes, and keep humans in the loop where it counts.

Open to GTM Engineer roles

Let's build the revenue engine.
