- INSO built cross-store business logic for Freaker USA (freakerusa.com), the Wilmington, NC brand (est. 2011) behind a one-size-fits-all beverage insulator made from recycled bottles.
- The campaign, built in collaboration with CTO Larsson, turns a new order on the partner site into a custom Freaker discount code per customer.
- Each customer gets a Klaviyo profile and a promo-code email, plus a reminder email if the code goes unused.
- The logic runs as custom business logic on AWS Lambda — described in the credit’s own words as "providing perfect stability" — with Node.js, Shopify, Liquid, and Klaviyo among the listed skills.
01 Introduction
Most Shopify work lives inside one store. This engagement lived between two. The public, client-named portfolio credit for Freaker USA documents a cross-store campaign built in collaboration with CTO Larsson: when a customer places an order on the partner site, custom logic mints them a personal Freaker discount code, creates their Klaviyo profile, sends the promo email — and follows up with a reminder if the code sits unused.
The credit reports no outcome metrics — so this page reports none. What it documents, precisely, is the shape of the system: what triggers it, what it creates, and where it runs.
02 The client
Freaker USA (freakerusa.com) is a Wilmington, North Carolina brand established in 2011. Its product is a one-size-fits-all beverage insulator made from recycled bottles — a single hero product with personality, sold direct on Shopify.
03 The cross-store campaign
The credit describes the campaign as a chain of events across two websites, built in collaboration with CTO Larsson:
- Order event received — new-order information arrives from the CTO Larsson website.
- Personal code minted — a custom Freaker discount code is created for that specific customer.
- Klaviyo takes over — a Klaviyo profile is created and the promo-code email goes out.
- Reminder if unused — a follow-up email is sent if the code hasn’t been redeemed.
That last step is the detail worth noticing: the campaign doesn’t end at "email sent." A per-customer code makes redemption trackable, and the credit’s flow uses that to close the loop with a reminder rather than letting the offer expire in an inbox.
04 The moving parts
The credit lists three delivered items:
- Custom business logic on AWS Lambda — described in the credit’s own words as "providing perfect stability".
- The Klaviyo flow — the profile creation, promo email, and unused-code reminder.
- Campaign support — INSO supported the campaign itself, not just the plumbing.
The credit’s listed skills include Shopify, Liquid, Shopify Templates, Node.js, JavaScript, and Klaviyo — storefront-layer work on the Shopify side plus the serverless and lifecycle-marketing stack the cross-store logic runs on.
05 The public record
Everything on this page traces to a single public source: the client-named portfolio credit "Freaker USA Shopify Store" (published January 11, 2023) 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 engagement dates beyond its own publication date, no hours, no fees, and no team size — so this page claims none. The phrase "providing perfect stability" is the credit's own self-published characterization, not a client-verified or independently measured result. 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.
06 Conclusion
The Freaker USA engagement is what partnership marketing looks like when engineering shows up: not a shared coupon code pasted on two homepages, but an event-driven loop — order on one site, personal code on the other, Klaviyo carrying the message, and a reminder making sure the offer doesn't die unopened. Serverless logic between two stores, per the credit, with the campaign supported end to end.

07 Frequently asked questions
- What did INSO do for Freaker USA?
- Per the public portfolio credit: INSO delivered custom business logic on AWS Lambda, a Klaviyo flow, and campaign support for a cross-store promotion built in collaboration with CTO Larsson. The flow receives new-order information from the CTO Larsson website, creates a custom Freaker discount code for that customer, creates a Klaviyo profile and sends the promo-code email, and sends a reminder email if the code goes unused.
- Who is Freaker USA?
- Freaker USA (freakerusa.com) is a Wilmington, North Carolina brand established in 2011. It makes a one-size-fits-all beverage insulator produced from recycled bottles, and its store runs on Shopify.
- Why run promo logic on AWS Lambda instead of inside Shopify?
- The credit states that the custom business logic was built on AWS Lambda and describes it, in its own self-published words, as "providing perfect stability"; it does not explain the architecture choice further. As general context about this class of work (not a claim specific to this engagement): logic that must react to events from a different website — here, orders on a partner store — has to live somewhere both systems can reach, and a serverless function that listens for the event, calls the Shopify API to mint the code, and calls Klaviyo to send the email is a common, low-maintenance shape for exactly this job.
- Did the project report any results?
- No. The portfolio credit describes the delivered scope — the cross-store logic on AWS Lambda, the Klaviyo flow, and campaign support — but reports no outcome metrics (no conversion, revenue, or code-redemption figures). This page therefore claims none. The one qualitative descriptor the credit offers is its own characterization of the Lambda logic as "providing perfect stability."
- Where does this information come from?
- One public source: the client-named portfolio credit "Freaker USA Shopify Store" (published January 11, 2023) on the Upwork profile of INSO’s engineering lead, Oleksandr (Alex) Mashkovtsev (upwork.com/freelancers/alexmv), checked August 31, 2026. It names the client, describes the brand and the cross-store campaign, lists the three delivered items and the skills — and this page states nothing beyond it.
