Marketplace Projects We've Delivered
Product Discovery for a B2B Social-Media Screening SaaS Platform
Challenge:
A UK screening firm ran its service as a manual, spreadsheet-driven process and wanted to turn it into an automated, multi-tenant SaaS product without committing a build budget before the core unknowns were resolved.
Solution:
Scoped manual workflow into 34 prioritized functional requirements with an MVP-versus-later split and 5 sign-off-flagged deferrals.
Reviewed an inherited prototype across 7 components and decided to replace them.
Isolated make-or-break unknowns into a ~1-week pre-build research phase with go/no-go gates.
Designed a GDPR-first architecture with isolation, PII encryption, audit logging, and data-retention controls built in.
Evaluated 6 build-vs-buy decisions across 3–4 alternatives each, every recommendation paired with a portability path so the choice stays the client's.
Result:
A buildable plan, the biggest unknowns de-risked up front, and compliance designed in.
Building Storefront CMS Blocks Across Multiple Retail Brands
Challenge:
A retail-focused e-commerce agency needed embedded frontend engineering capacity to deploy across three brand engagements (Solo Stove, Crocs, and Coach) running on different Salesforce Commerce Cloud frontends.
Solution:
Brought multi-framework Salesforce coverage so engineers can deploy to any brand engagement.
Built modular CMS components across three retail brand engagements (Solo Stove, Crocs, Coach), themed per brand and integrated with live Salesforce product data.
Improved Web Vitals metrics across the storefronts and integrated payment systems into the Solo Stove SFRA-based checkout.
Result:
Engineering across three retail brands, Salesforce frontend coverage, and Web Vitals improvements across the storefronts.

Solution:
Built a full-featured e-commerce website with React and Vue.js supporting dual transaction models.
Integrated Stripe and Vipps for secure payment processing with voucher and payback support.
Connected local postal services Postnord and Helthjem for C2C book delivery.
Developed an automated competitive intelligence system for price monitoring across marketplaces.
Result:
Launched a complete B2C and C2C platform with seamless multi-provider payments and an automated competitive pricing system, supporting the platform's growth to 450K+ users and expansion from Norway to Sweden.
Building a Scalable E-Commerce & Subscription Platform
Challenge:
A SaaS marketing technology platform needed to scale its product and migrate subscription billing.
Solution:
Built core platform features: credit borrow flow, attribute enrichment, configuration tools, redesigned onboarding, reports, and contracts.
Migrated subscription billing from Chargify to a configurable Salesbricks model.
Designed domain-separated serverless subsystems on GCP with an event-driven configuration layer.
Result:
