INSO.codes

INSO.codes is a five-person Shopify development studio based in Poland. Founded by Alex Mashkovtsev, the team includes two full-stack engineers (Alex Bulakh as lead developer, Paul Morozov as front-end specialist), a UI/UX designer (Angelina Vodianytska), and a project manager (Anastasiia Streletska). On Upwork, they've completed 47 jobs with a 100% success rate and logged over 5,000 hours. They claim 30+ client relationships.

Services and capabilities

INSO.codes handles the full Shopify stack: custom theme development from scratch, UI/UX design, Shopify app development, conversion rate optimization, platform migrations (from WooCommerce or Webflow), and e-commerce consulting. Their in-house design team moves from mockups to functional interfaces. For custom features, they build Shopify apps when the platform's native capabilities don't fit. On their services page, they rate their own proficiency at Theme Development and Custom Scripts/Services at 100%, UI/UX Design at 100%, and Shopify Apps at 90%.

They've worked on checkout redesigns and custom landing pages. One client (Goodfair) saw a stated conversion and AOV lift of 10% after INSO.codes rebuilt their Shopify site and checkout. Another (also Goodfair, per a second testimonial) used INSO.codes to build custom Shopify applications to reduce reliance on third-party tools.

Notable work

Named projects include Goodfair (theme design, app development, custom integrations, checkout redesign), Antinol (theme design, custom integrations), Bearco (theme design, custom integrations), and Freaker USA (custom functionality). Testimonials come from Global Project Lead at Antinol, a Product Manager at Goodfair, CEO of Magic Valley, CTO of Artifax Software, and a Head of Ops at Goodfair. Most praise focuses on Alex Bulakh's technical depth and responsiveness, though several note his willingness to go beyond scope on difficult projects.
