Web experiences that ship and scale.

Freelance web development for ambitious founders. Vue, Nuxt, Shopware, and ten years of building things that don't break in production.

    One partner

    You talk to me. No agency layers, no ticket queues.

What I do

Specialist services for e-commerce that converts.

Shops built, migrated and extended — then kept fast, measurable and accessible. From platform work and integrations through AI enablement, tracking, performance, and the audits that keep it all honest.

Included

Shop platforms & migrations

Shopware and Shopify — built, extended and moved. From ERP-shop-to-Shopify migrations with order history to custom storefront features like shareable product configurators.

  • JTL / legacy shop → Shopify
  • Shopware features & CMS blocks
  • Launch checks: SEO, SEA, mails

Included

AI & enablement

Practical AI in your stack and in your delivery process — product search, content workflows, MCP-connected coding agents and scheduled automations — plus the training to make your team confident running it.

  • LLM, RAG & MCP integrations
  • Agent workflows & automation
  • Team workshops & enablement

Included

Integrations & automation

I connect the systems you already run — shop, ERP, PIM, CDN, payment, marketing — automate the manual work between them, and prove with evidence where data stops when something breaks.

  • REST APIs & new endpoints
  • PIM / ERP / CRM sync
  • Root-cause debugging across systems

Included

Conversion rate optimization

Turn the traffic you already have into revenue. Data-led hypotheses, clean A/B tests, and checkout, navigation and product-page flows that remove friction instead of adding it.

  • Funnel & checkout analysis
  • Navigation & PDP optimization
  • A/B testing & experiments

Included

Tracking, analytics & consent

Trustworthy measurement that survives an audit. Server-side tracking and GA4 paired with a consent setup that is both GDPR-compliant and data-complete.

  • GA4 & server-side tracking
  • Consent management (CMP)
  • GDPR-compliant data layer

Included

Performance & Core Web Vitals

When your store is slow and you don't know why. LCP, INP, and CLS triaged with real-user data — then fixed at the renderer, not the surface.

  • LCP / INP / CLS triage
  • Bundle & image strategy
  • Renderer-level fixes

Included

Accessibility (BFSG)

E-commerce accessibility that meets the EU Accessibility Act — usable for everyone, defensible for you, and without compromising the design.

  • WCAG 2.2 / EN 301 549
  • Keyboard & screen-reader audits
  • Remediation with your team

Included

Audits

A clear, prioritized picture before you spend a cent on fixes — accessibility, performance, SEO, and SEA, scored and turned into an actionable roadmap.

  • Accessibility & performance
  • SEO & SEA / paid search
  • Prioritized action roadmap

Outcome

Tracking, speed, and conversion stay connected, so the next fix is clear before the backlog gets noisy.

The workflow

  1. ScopeScoping call to written plan.
  2. BuildType-safe, tested, observable.
  3. ShipFirst deploy in days, not months.
  4. ScaleHeadless storefronts that hold at peak.

Ship. Then scale.

Scope it, build it, ship it, scale it. One partner, start to finish.

“Headless Shopware can be a swamp. Marco navigated it. Our storefront LCP went from 4.1 s to 1.2 s.”

FAQ

Common questions, answered.

A 30-minute call. We talk about what you’re trying to ship, who it’s for, and what success looks like. After that you get a written scope with timeline and price — fixed, not hourly when possible.
Vue/Nuxt + TypeScript on the front. Node, Postgres, Shopware on the back when it fits. I pick what your team can keep maintaining.
Yes. Embedded in your Slack, your repo, your sprint cadence. I also do fractional CTO work for founders who don’t have a senior engineer yet.
Fixed-scope projects start around €8k. Retainer engagements from €4k/month. Audits from €1.5k. I’ll always tell you up front whether I’m the right fit.
