- INSO worked for Andcopenhagen (andcopenhagen.dk), a Danish luxury jewelry and cashmere brand, in the role of Lead Shopify Engineer, starting March 2021.
- The publicly credited scope is four storefront and marketing surfaces: newsletter signup banner UI/UX, a custom cookie-consent popup, an admin-customizable Free Shipping banner, and post-purchase SMS marketing optimization.

- This page claims only what the public, client-named credit states: no invented metrics, no invented scope, no guessed timeline beyond the stated start.
01 Introduction
Not every valuable Shopify engagement is a rebuild. Starting in March 2021, INSO worked as Lead Shopify Engineer for Andcopenhagen, a Danish luxury jewelry and cashmere brand — and the publicly credited scope is a set of four precise storefront and marketing improvements rather than one big project. This case study is sourced from the public, client-named portfolio credit for that work, published on the Upwork profile of INSO's engineering lead.
Because the source is a portfolio credit rather than a contract record, this page is deliberately narrow: it reports the client, the role, the start date, and the four scope items the public credit states — and nothing it doesn't.
02 The client
Andcopenhagen (andcopenhagen.dk) is a Danish luxury brand selling jewelry and cashmere. It runs on Shopify. For a brand in that segment, the storefront's small interactive surfaces — banners, popups, notifications — carry the same expectation of polish as the products themselves.
03 The four improvements
The credit lists four deliverables, each a distinct storefront or marketing surface:
- Newsletter signup banner UI/UX — the store's main first-party audience capture surface, redesigned for how it looks and how it behaves.
- Custom cookie-consent popup — a consent surface built for the brand rather than dropped in from a generic widget.
- Admin-customizable Free Shipping banner — a promotion bar the Andcopenhagen team can change themselves from the Shopify admin, without a developer in the loop.
- Post-purchase SMS marketing optimization — improving what happens in the messaging channel after the order is placed.
The credit's listed skills include Klaviyo, SCSS, and Liquid — which matches the shape of the work: theme-layer engineering (Liquid, SCSS) wired into the marketing stack (Klaviyo).
04 Why small surfaces matter
Some general context — about this class of work in general, not a claim about this specific engagement: signup banners, consent popups, and shipping bars are the highest-traffic UI a store has, because every visitor sees them regardless of which product they came for. They are also where off-the-shelf widgets most visibly clash with a luxury brand's design language. Building them custom, and making them admin-editable, moves day-to-day marketing changes from a developer queue to the merchant's own team — which is often the real deliverable.
05 The public record
Everything on this page traces to a single public source: the client-named portfolio credit "Andcopenhagen Shopify Improvements" on the Upwork profile of INSO's engineering lead, Oleksandr (Alex) Mashkovtsev, at upwork.com/freelancers/alexmv (checked August 31, 2026).

The portfolio credit states no end date, no hours, no fees, no team size, and no outcome metrics — so this page claims none. Upwork's public data also does not state which contract this project belongs to, so this page draws no connection between this credit and any contract record. What the credit does state — client, role, start, scope, skills — is reported here in full.
06 Conclusion
The Andcopenhagen engagement shows what sustained Shopify work looks like between the headline rebuilds: a named engineer in a named role, improving the exact surfaces every visitor touches — capture, consent, promotion, post-purchase — with the merchant left able to run one of them without developer help. It's publicly documented, with the client named, on a profile you can check yourself.
