HI, I'M PETER
I'm a creative developer who combines AI with e-commerce to build high-converting Shopify stores. My approach means shorter timelines and lower cost — without sacrificing quality.
I'm obsessed with the details and focused on one thing: turning your store into real revenue. From CRO to custom builds, I ship fast — and I ship it right.
MY RATE IS $35/HR.
YOUR TOTAL IS FAR LESS.
Here's the part most people miss: your total isn't the rate — it's the rate × the hours, and I keep both low. A $35/hr rate is already a fraction of agency pricing, and AI-accelerated delivery means the build takes a fraction of the hours. Lower rate × fewer hours = a total that undercuts agencies by ~83% — with the same senior-level, conversion-focused quality.
Illustrative example for a typical Shopify build — your exact scope sets the real number. The takeaway is the shape: a lower rate multiplied by fewer hours is a dramatically smaller total, without cutting quality.
Why it's cost-effective — not cheap
No agency overhead
You pay for the developer — not account managers, sales teams, project layers, or office rent. One person, working with you directly, end to end.
AI-accelerated speed
I lean on AI across scoping, building, and QA, so the same work takes a fraction of the hours. Fewer hours at a lower rate is where the real savings come from.
Senior-level quality
AI does the heavy lifting; I review every line by hand. You get agency-grade, conversion-focused output — just without the agency invoice.
MY EXPERTISE
Shopify is my home turf — but I build across the stack: websites, web & mobile apps, and AI automation, all AI-accelerated and shipped fast.
E-Commerce Development
Custom online stores built for speed and conversion. Shopify is my specialty — Plus themes and headless Hydrogen — and I also build on WooCommerce, BigCommerce, and Webflow. Stores that sell, shipped fast and affordably.
AI-Accelerated Development
My biggest edge: heavy use of AI tooling alongside modern web tech. It means shorter timelines and lower cost — the same quality build, delivered in a fraction of the usual time.
Conversion Rate Optimization
Turning a store into real income is what I'm best at. Data-driven CRO audits, A/B testing, and iterative optimization to remove every point of friction between visitor and purchase.
Store Migration & Performance
Moving to Shopify or off a slow theme? I handle migrations cleanly and tune your store for speed — faster pages, preserved SEO, and a checkout buyers trust.
AI Commerce Features
AI woven into your store where it moves a number — smart product recommendations, intelligent search, and AI-driven support, built on your real data, not hype.
Analytics & Growth
Clean analytics, clear dashboards, and honest reporting — so you know what's actually driving sales and where your spend is working, not just a wall of numbers.
Website Design & Development
Fast, modern marketing sites, landing pages, and corporate websites — designed to convert and built on clean, maintainable code. Not just a store; whatever your brand needs online.
Web Application Development
SaaS platforms, dashboards, internal tools, and customer portals — full-stack web apps built with Next.js and TypeScript, shipped fast with AI-accelerated tooling.
Mobile App Development
iOS and Android apps from a single codebase — cross-platform mobile development in Flutter, React Native, or Ionic, built fast and polished so your product ships to both stores at once.
AI Solutions & Automation
Custom AI products and automations — chatbots, LLM-powered apps, RAG assistants, and workflow automation that save hours and scale what your team can do. Built on your data.
API & Backend Engineering
REST and GraphQL APIs, integrations, databases, and cloud backends — the reliable engine behind your app or store. Built to scale, documented, and easy to build on.
THE PROCESS
A tight, AI-accelerated approach that takes you from brief to a live, converting store — fast.
Discover & Scope
I dig into your brand, audience, and revenue goals, then use AI tooling to turn it into a clear, concrete plan — scope, timeline, and price agreed up front, no surprises.
Design
Conversion-first design with the details that matter. Every screen is planned around how people actually buy, and refined with your feedback before I start building.
AI-Accelerated Build
I build fast with AI-assisted tooling, then review and test everything by hand. Clean, documented code and frequent check-ins — quick progress you can see, without the corners cut.
Launch & Optimize
A clean, zero-downtime launch, then post-launch monitoring and CRO. I keep tuning conversion after go-live so the store earns more over time, not just on day one.

I lean hard on AI tooling across scoping, building, and QA. That means shorter timelines — often two to four weeks — where a traditional agency might quote a couple of months.

COMMON QUESTIONS
The quick answers most people want — or ask the assistant up top for anything else.
What does Peter build?
High-converting Shopify and e-commerce stores, plus custom web apps, marketing sites, and AI features — all AI-accelerated so they ship fast and affordably.
How much does a Shopify store cost?
Quick fixes start at $50, small sites from $300, and a full custom Shopify store from $1,500. Ongoing conversion optimization is priced flexibly — scaled to your store's size and traffic so it fits your budget — and larger custom builds are quoted after a short scoping call.
How long does a project take?
Small sites go live in about a week; a full custom Shopify store typically takes 2–4 weeks. AI-accelerated tooling keeps timelines short without cutting quality.
Can you improve my existing store's conversion rate?
Yes — CRO is a core service. Peter audits your funnel with analytics and session data, runs sound A/B tests, and ships changes that compound revenue over time.
Is this legit — who am I working with?
You work directly with Peter Nowak (trading as Rivet Commerce), a real, named developer — not an anonymous agency. Every project runs on a clear scope and contract with milestones, and you sign off before the final payment.
How do we get started?
Send a message from the contact page with a bit about your project. Peter replies personally, usually within a day, then scopes it with a short discovery call and a fixed quote.
Can I get my store reviewed before committing to anything?
Yes — the free store audit is exactly that. Send your store URL and Peter goes through it by hand, then emails back a short, prioritized list of what's costing you sales, usually within 48 hours. No signup, no card, and no obligation afterwards.
Which platforms do you work with?
Shopify is the specialty — custom Plus themes and headless Hydrogen storefronts — and builds also run on WooCommerce, BigCommerce, and Webflow when one of those is genuinely the better fit for your catalog and team.
Do I own the code and the accounts when we're done?
Completely. On full payment, all custom code, designs, and IP are yours, with documentation to match, and account ownership is handed over at the end. No lock-in and nothing held hostage.
You use AI — does that mean lower-quality work?
The opposite is the intent: AI does the heavy lifting on scaffolding and QA, then every line is reviewed by hand before it ships. That's where the short timelines come from — fewer hours at a lower rate, not corners cut on the output.
How do payments work?
A fixed quote is agreed up front rather than a running meter of billable hours, then billed against clear milestones — you review and sign off before the final payment. Pay securely by card, PayPal, or bank transfer against a proper invoice.
What happens after launch?
Launch itself is handled carefully with no downtime, and Peter stays available afterwards to fix, tune, and help you grow. Ongoing conversion work is priced flexibly and scaled to your store's traffic, so it's there if you want it and never an obligation.

Where your store gets built.
Hands-on Shopify, custom code, and conversion work — from the same developer who scopes your project. Detail-obsessed, from first call to launch.
