The Summa Development team
Three senior specialists, one shared goal: we build and grow online stores that are secure, fast and genuinely profitable. From design through development to advertising, we keep it all in one hand.
Design, development and marketing in one place
Summa Development is a development and e-commerce studio where design, technology and marketing go hand in hand.
We don’t just build an online store, we build a working business: custom development solves what ready-made templates can’t, while measurement and advertising make sure the work turns into real revenue. Three disciplines, one team — from the design through the code to the conversion.

Meet the specialists
Three senior specialists who together cover the full lifecycle of your online store.

Sándor Ferenczi
Senior WordPress–WooCommerce developer
Custom plugins, backend automations and external integrations — Sándor’s work begins where ready-made templates reach their limits.

Álmos Sörös
Senior WooCommerce developer & e-commerce manager
PPC campaigns, precise measurement and front-end development — Álmos drives store growth from the ad click to the conversion.

Annamária “Ami” Ferenczi
Designer
Web design, branding, illustration and 2D/3D animation — Ami makes sure that what we build looks right and, when it should, moves too.
What working together means
You don’t get separate services — you get a team that sees the whole picture.
End-to-end coverage
Development, marketing, measurement and design in one place — no need to coordinate several vendors.
Measurable results
We don’t make empty promises: every decision is backed by real data and precise measurement.
Long-term partnership
We think in shared, long-term growth, not one-off projects.
