Senior Growth Engineer · AI Automation

I build growth systems, delivered as working software.

From PLG funnels and GTM automation to voice AI agents and real-time analytics — I turn growth ideas into shipped infrastructure for SaaS companies.

The operating principle

Most growth advice stays a slide deck. My deliverable is shipped infrastructure — funnels, agents and automation that run in production and compound while you sleep.

01Live workspace

A portfolio that actually ships.

Real builds, real stacks. This panel reads from the same data that powers the case studies below — no mockups.

02How I work

From growth idea to shipped system.

01

Find the constraint

I start where growth actually breaks — activation, funnel leaks, manual ops — not where it is loudest.

02

Ship the system

PLG flows, GTM automation, voice AI agents — built as real infrastructure, not throwaway scripts.

03

Measure & compound

Instrument every surface, watch the metric move, and keep the wins recurring.

Things I've shipped.

Digital products, growth experiments, and AI integrations — each one live, instrumented, and in use.

RunMend
FeaturedSaaS2026

RunMend

Growth stacks don't crash — they go quiet. RunMend polls the native API of every tool in your stack and catches the failures nobody alerts on: streams enabled but sending zero events, spiking error rates, feeds that went stale, webhooks and monitors left blind. Read-only keys, no snippet on your site, no receiver to babysit — and the detection engine is open source.

Manatki
Open Source2026

Manatki

An open-source AI studio that turns a memo, a doc, or a single sentence into an on-brand deck or a full campaign. It extracts a design system from your site or brand doc, then checks every slide against it deterministically — flagging off-palette colors and non-brand fonts with fixes. Imports PDF, PPTX, DOCX, Google Docs and URLs; exports editable Google Slides, PPTX, PDF, HTML and PNG. Free, bring your own key.

Sennet
Growth2026

Sennet

A two-week sprint that tells B2B SaaS teams which user behaviors actually predict retention. Sennet mines your product data to deliver an empirically-defined activation metric, a PQL scoring model, an event taxonomy, and monitoring dashboards — replacing vanity metrics with signals that hold up, plus three months of monitoring so the taxonomy doesn't rot.
