SEO

Clean URLs and automatic 301 redirects

Same client, separate technical task

The site engine gained custom, human-readable URLs for any page instead of the old id-plus-duplicate scheme, plus a 301-redirect table from the old addresses — accumulated SEO traffic isn't lost when URLs change.

Deployed to production with a full DB backup, regression-checked against 8+ points

AI ASSISTANTS & AUTOMATION

AI search

Robust search across a 5,000+ product catalog

Online store for sewing supplies

The AI advisor stopped losing customers to typos, mixed Ukrainian/Russian product names and brand transliteration — plain text search missed all of it.

Control run of 16 real customer queries: 14 of 16 before the fix, 16 of 16 after — twice in a row
5,044 products16/16 hit rate

Automatic stock updates on Prom.ua

Electrical goods supplier

The supplier's daily price list arrives by email — a script parses the Excel file itself, matches items by SKU against the catalog, and updates storefront stock with zero manual work.

Control run: 4,760 line items parsed, 4,223 updated, 0 errors

SMM demo stand

One post → 4 social adaptations + a reception bot for a driving school

SMM automation · driving school

A single client post automatically unfolds into adaptations for different platforms and formats and publishes itself — no manual work. In parallel, a bot answers routine student questions around the clock and hands warm leads to a human admin. By volume of routine work it covers the bulk of an SMM manager's job — not all of it: ad buying and live talks with a hot lead still need a person.

Our own demo stand to show the approach — not a client order. The hourly posting schedule shown is a typical pattern for evening-demand niches, not a measurement from this specific business.
