Specialization
E-commerce, WMS, integrations. Zero "side" projects.
About
Engineering studio from Białystok
Semafi is a boutique engineering studio. We help brands build custom e-commerce infrastructure — from a single store to full WMS systems with marketplace integrations and dedicated desktop apps.
Standard platforms (Shopify, Woocommerce, Magento) work well in 80% of cases. The other 20% are brands that outgrew off-the-shelf — too many SKUs, too many sales channels, too complex operations. That's where we come in.
We treat every project as engineering — design the architecture, pick the stack to fit the problem, write code that stays yours (zero vendor lock-in). After launch we don't disappear — SLA, monitoring, hotfixes.

What clients say
5.0/5 average rating from Google reviews.
Semafi rewrote our entire warehouse from Excel into a proper WMS. Order packing time dropped 40%, shipping mistakes practically went to zero.
We tried Shopify and Woocommerce. Only the custom Semafi store could handle our 120+ product variants and integration with 3 wholesalers at once.
Allegro + Amazon + eBay integration with our system. Done in 6 weeks, running for half a year without intervention. Recommended.
