/ SERVICES — SIX LINES

What I
build.

Six service lines, all delivered end-to-end by one senior engineer. Shopify, SaaS, and AI are the primary work. Webflow and WordPress when the brief is genuinely a content site.

/01 — SHOPIFY

Shopify stores.

End-to-end Shopify builds: theme development from Figma, Shopify Plus support, custom Liquid sections, product and landing pages, checkout tweaks. Stores load fast, convert, and stay editable by the team.

  • Custom themes built from Figma — no off-the-shelf theme rewrites.
  • Shopify Plus features: scripts, flow, checkout extensions, B2B.
  • Product-page logic the platform does not ship natively — auto-discounts, line-item properties, shipping protection.
  • Configurable sections so the team can re-merchandise without code.
  • Mobile-first responsive; performance budget enforced from day one.
  • Shopify
  • Liquid
  • Shopify Plus
  • Custom Sections
  • Figma
/02 — APPS + API

Shopify custom apps.

Bespoke Shopify apps and API integrations for problems no public app solves. Subscriptions, loyalty, ERP sync, custom coupon APIs, headless storefronts on Hydrogen — all with order-webhook plumbing that hands off cleanly to back-office tools.

  • Custom apps in Node + Shopify Admin API with proper webhook handling.
  • Hydrogen headless storefronts when a traditional theme is the bottleneck.
  • ERP and POS sync — inventory, orders, customers — two-way.
  • Subscriptions, loyalty, custom checkout flows tied to merchant rules.
  • Multi-vendor SaaS layered on top of Shopify for partner ecosystems.
  • Shopify Admin API
  • Hydrogen
  • Node
  • Webhooks
  • Multi-tenant SaaS
/03 — PERFORMANCE

Speed and conversion.

Core Web Vitals tuning, image and JS budgets, mobile-first design passes, checkout funnel fixes. The same traffic, more orders. Measurable lifts in LCP, CLS, and checkout completion.

  • LCP, CLS, INP, TTFB tuned page by page against a real-user budget.
  • Image pipeline, font loading, render-blocking JS audited and reduced.
  • Checkout funnel instrumentation and A/B-tested fixes.
  • Mobile experience pass — design, performance, accessibility.
  • Lighthouse
  • PageSpeed
  • PostHog
  • Real-user metrics
/04 — SAAS

SaaS products and dashboards.

Production SaaS products built end-to-end — auth, billing, multi-tenant data, dashboards, integrations. Next.js, React, TypeScript on top of Postgres with Prisma. Stripe for billing. Twilio, Nylas, S3, Docuseal when the product needs them.

  • Next.js + Postgres + Prisma multi-tenant data models that scale across tenants and practice areas.
  • Stripe billing — subscriptions, metered billing, customer portal.
  • Twilio voice + SMS, Nylas email + calendar, S3 documents, Docuseal eSign — integrated against a single domain model.
  • Custom dashboards with charts, exports, role-based access.
  • Widget SDKs to embed product surfaces on external sites and landing pages.
  • Next.js
  • React
  • TypeScript
  • Postgres
  • Prisma
  • Stripe
  • Tailwind CSS
/05 — AI / AGENTS

AI web apps and agents.

LLM-powered web apps, automation tools, and AI agents for internal teams and customer-facing surfaces. RAG pipelines, evals, streaming infrastructure that holds up in production. Not demos — products.

  • OpenAI APIs (and other providers) wired into Next.js apps with proper streaming.
  • Retrieval-augmented generation (RAG) over real documents — Postgres + embeddings, with eval rubrics.
  • Multi-step AI agents that call tools, branch, and self-check.
  • Prompt versioning, eval suites, and observability so the AI doesn't regress silently.
  • OpenAI
  • RAG
  • Agents
  • Evals
  • Streaming
/06 — SITES

Webflow and WordPress.

Marketing sites and content-driven websites when a content site is what's actually needed. Custom WordPress themes (no page-builder bloat) and Webflow builds with clean CMS structure, fast page loads, and editing the team can actually do.

  • Custom WordPress themes from Figma — no off-the-shelf page-builder lock-in.
  • Webflow builds with structured CMS collections and clean URL hierarchy.
  • SEO baseline: meta, OG, structured data, XML sitemap, canonical handling.
  • Editor-friendly content blocks so the team owns the content after launch.

  • Webflow
  • PHP
  • Advanced Custom Fields
