01Catalog / UX↗
Carbon District
Navigation and catalog logic for more than 6,000 automotive products without the overwhelm.
Shopify Developer
I design and develop Shopify stores — from the first structure through launch and continued growth.
Not a template.
A system.
Postnov Development is the Shopify practice of Illia Postnov. Structure, design, Liquid and launch stay in one pair of hands — so nothing gets lost between stages.

From intent.
To system.
First, define what customers need to understand and what they should do next.
Four stages.
Always visible.
You see the work in progress, understand the next step and make decisions before they become expensive.
Scope
Clarify the goal, customer, catalog, content and integrations. Agree the scope, priorities, schedule and definition of done.
Design
Shape the key journeys and responsive screens. Structure, behavior and visual direction are agreed before development begins.
Build
Create the editable Liquid theme, metafields and integrations. Working versions stay open for review throughout the build.
Launch
Test devices, the path to checkout, performance and content. Your team leaves knowing how to run and evolve the store.
Illia Postnov.

Answers.
Up front.
End-to-end stores, custom Liquid themes, redesigns, migrations, integrations, catalog work, performance improvements and focused custom features.
It depends on catalog size, content readiness, design and integrations. After a focused review, we agree a realistic plan and clear checkpoints.
Pricing follows the actual scope and complexity, not a generic page count. Before work starts, you receive a clear list of deliverables and project boundaries.
Both. I can translate an existing Figma design and complete missing states, or shape the UX, interface system and key screens from the ground up.
Yes. I plan the new structure, migrate products and content, configure the required data model and check that critical information survives the move.
Yes, when the task has a clear purpose: a new section, filter, form, integration, bug fix or improvement to a specific customer journey.
Yes. I configure options available for your market and test them as part of the complete order journey.
Yes. I first identify real bottlenecks in the theme, third-party code and media, then address what materially affects loading and interaction.
Yes. Content, sections and data are structured around Shopify’s theme editor, metafields and metaobjects so routine updates do not require code changes.
I hand over the store with the context your team needs. From there, we can work task by task, plan the next phase or continue with ongoing development.
