Founder arc

Companies I built

2009 — 2016
Webinse
Scaled a serious eCommerce engineering team

Webinse was where I learned how to turn talent into a company: Magento delivery, international clients, project management, support, finance, hiring, and internal systems that could survive real client pressure.

  • Built and led a multi-function organization across Magento, WordPress, design, QA, PM, support, HR, finance, and operations.
  • Delivered recurring work for international clients including Gavriele Brands, Foto Video Zumstein, KKL Luzern Management, ATO24, and Chaussures Aeschbach.
  • Created Webinse Academy so we could recruit, train, mentor, and graduate junior talent into production teams instead of waiting for the market to hand us seniors.

Fruitfulcode
Productized the engineering machine

Fruitfulcode turned our delivery muscle into products: WordPress themes, plugins, demos, support content, analytics, and purchase funnels. It was not just code. It was packaging, distribution, documentation, and iteration.

  • Shipped and maintained products including Fruitful Theme, Fruitful Shortcodes, Maintenance, Zoner, Movement, Spotter, Suburb, THX, and Soon.
  • Built support and documentation flows that attracted more than 46,000 help-center pageviews during the analyzed 2018-2019 period.
  • Ran analytics around downloads, demo views, purchase intent, organic traffic, paid traffic, and retargeting audiences.

Mates Marketing
Built a conversion engine for home-improvement brands

Mates Marketing took the same operator mindset into growth: landing pages, paid media, creative testing, compliance, ZIP targeting, API integrations, and client success for US home-improvement companies.

  • Built lead-generation systems for walk-in showers, walk-in tubs, roofing, solar, gutter protection, kitchen cabinets, and related verticals.
  • Packaged exclusive TCPA-compliant leads with landing-page setup, ad creatives, campaign preparation, ZIP targeting, and API integration.
  • Reached a documented $1M+ revenue milestone while reporting 25-50% lead-to-appointment conversion ranges across campaigns.

LeadCognition
Founder · CTO

Building LeadCognition.io — an AI-native product that turns public developer signals into account intelligence, buyer context, and outreach worth sending. MCP-ready workflows for developer-led sales.

  • Building AI workflows that turn public code activity — commits, repos, stack choices — into account signals and buyer context.
  • Combining founder judgment with hands-on architecture across TypeScript, modern web stacks, automation, analytics, and AI tooling.
  • Focused on software that creates leverage: faster teams, cleaner pipelines, better decisions, and measurable revenue outcomes.

Working style

Useful where the org chart gets blurry.

01

I stay close to the work

I do not manage from a balcony. I can enter the codebase, the offer, the hiring loop, the sales funnel, or the finance model and help turn ambiguity into execution.

02

I build systems, not heroics

A good company should not depend on constant firefighting. I look for repeatable playbooks: training pipelines, support loops, campaign systems, analytics, and team habits that compound.

03

I care about revenue-quality engineering

The best technical work makes a business sharper: faster delivery, better conversion, clearer operations, happier customers, and fewer expensive blind spots.

Open to engagements · 2026

17 years of building. Now available for a few fractional engagements.

Fractional CTO · AI GTM · RevOps. I work best with founders who have a real decision in front of them — not just an open calendar slot.
