Retail apps from a founder who’s worked on one at scale
Denys Havryliak, Applefy’s founder, has worked on New Look’s enterprise retail app, used by 7M+ people. That is his personal professional experience — it is not an Applefy case study, and this page says so rather than dressing it up. Here is what that background brings to a retail build.
What this experience brings
Retail apps live or die on search, checkout, and the care taken with every release. Denys’s background is enterprise iOS at that scale, and how Applefy approaches a retail build follows from it.
Enterprise retail, first-hand
Denys Havryliak has worked on New Look’s enterprise retail app, used by 7M+ people. It is his own professional experience, not an Applefy delivery.
Founder-led from the first call
Denys takes the first call on every project, so a retail founder talks to someone who has worked on a retail app — not to a sales layer.
A domain specialist, on request
If your corner of retail — luxury, marketplaces, resale, grocery — needs deeper expertise than one founder’s, say so in the booking form’s industry field. We connect a specialist from your domain within 48 hours.
Security review in-house
Applefy runs OWASP/NIST-based Cybersecurity Audits as a standalone service, so a checkout can get a second set of eyes before it goes live.
What we build for retail products
Product Discovery & Catalog
Search, filters, sorting, and product pages that move shoppers toward checkout, against the catalog and stock data your own systems provide.
Checkout & Payments
Guest and signed-in checkout, saved payment methods, and order confirmation, handed to your payment provider so card data never touches your servers.
Accounts & Loyalty
Sign-in, saved items, and points or offers wired to your loyalty or CRM backend — the app presents what your systems decide.
Orders & Returns
Order status, notifications, and return flows built against the order-management and fulfilment systems you already run.
Where this comes from
New Look — enterprise retail app (Denys Havryliak’s personal experience)
The retail app of New Look, a UK fashion retailer, used by 7M+ people. Denys shipped enterprise iOS there. This is his personal professional experience, not an Applefy project — there is no Applefy case study for it.
Common questions about fashion and retail app development
Not as an Applefy case study. Denys Havryliak, Applefy’s founder, has worked on New Look’s enterprise retail app (7M+ users) — that is his personal experience, and this page says so instead of presenting it as company work. Our published case studies are in fintech, construction, health and wellness, and travel and lifestyle.
We build checkout flows that hand card data to your payment provider, so raw card numbers never touch your servers. We don’t process payments and we don’t issue PCI attestation — that comes from a PCI SSC-qualified assessor, or from self-assessment if your merchant level allows it. A Cybersecurity Audit can review the build beforehand.
Depends on the project. We can build the app against the APIs your team already exposes, or take on the backend too — on Kiolfast we own the backend outright. Tell us your stack and what exists today, and we’ll scope accordingly.
The same three tiers as any Applefy project: $20K–$40K (3–6 weeks), $40K–$100K (2–4 months), and $100K–$250K+ (4–8 months). Where a retail app lands depends on scope — catalog and checkout integrations, loyalty, and how many platforms you need.
Retail is broad — fashion, grocery, marketplaces, resale. If your niche needs expertise beyond what one founder brings, put it in the industry field of the booking form and we’ll connect a specialist from that domain within 48 hours.
