Shopify development, AI automation, and custom software — led by a senior partner.
Three ways to work with us, one accountable partner across all of them. Whether you need a Shopify build, the busywork automated, or a product that doesn’t exist yet — you deal directly with the engineer leading the work.
Three ways we can help you.
Pick the one that sounds like your problem. If none of them quite fit, say so on a call — we’ll tell you straight whether we’re the right people.
Shopify Development
You sell on Shopify and need it built, fixed, or kept running.
Custom themes, sections and snippets built to your design — plus private apps and Shopify Functions for the functionality no app-store app covers, and ongoing maintenance for your store and its third-party apps.
AI Automation
Your team is buried in manual work — on Shopify or anywhere else.
Support and sales agents, AI-personalized email flows, inventory and reconciliation automation, and visibility inside ChatGPT and Google AI answers. Built for ecommerce brands on any platform.
Custom Software
You need a product that doesn’t exist yet.
Fullstack web apps and dashboards in Next.js, Node and Postgres or Supabase — plus native mobile in React Native and Expo. From first MVP through to scale.
Most people find us at one of four moments.
You don’t need to know which service you need, or what to call it. If one of these sounds like your week, we’ve fixed it before — and we’ll tell you which lane it belongs in.
Your store is close to the design but never quite right, and every new section turns into a week of dev tickets.
The feature you need doesn’t exist in any app — or it does, bundled at $400 a month for the one thing you actually use.
Your team copies data between tools, answers the same “where’s my order?” fifty times a week, and chases oversells.
The last developer shipped late, left a mess, and now nobody wants to touch the code.
Ownership and clarity, from people who'd know.
“The Lead Developer was one of the best frontend developers I have ever worked with. Easy to trust. Strong ownership. Delivered what they committed to.”
“Extremely professional in communication and ownership of tasks. Quick to take direction and run with it to efficiently produce high-quality work.”
“Very pleased to have worked with Sleek App. The team was able to quickly grasp the requirements of our complex project and deliver the initial deliverables in good time.”
Scope. Build. Ship. Maintain.
The same process whichever lane you came in through. Clear communication, systemized updates, and outcomes you don’t have to babysit — you always know what’s done, what’s next, and what’s blocked.
Scope & quote
We map what you need, what it will cost and what could go wrong — before anyone signs anything.
Build & ship
Senior engineering, weekly check-ins, clean delivery. Quality you don’t need to review line by line.
QA & launch
We finish strong — testing, hardening and launch support, not “good luck from here.”
Maintain & extend
Ongoing maintenance, monitoring and new features on a retainer — if you want us to stick around.
