Key cases

E-com contour: Bitrix ↔ 1C, sales channels & order fulfillment

1C-Bitrix · D7 · 1C · REST · MySQL · Marketplaces · Delivery · Payments

Storefront end-to-end: catalog and orders, 1C exchange, marketplaces, delivery, payments and SMS — ongoing delivery and production desync triage.

Challenge

Exchange, feed, delivery or payment failures hit revenue immediately. Needed someone who owns the full commerce contour.

Solution

  • Site ↔ 1C exchanges: catalog, stock, prices, orders; sync-error diagnostics
  • Catalog, cart, promos, SEO and antifraud on a loaded Bitrix CMS/Aspro
  • Marketplaces: feeds/exports, product and order sync
  • Delivery services and payment/SMS checkout contour
  • Wiring external APIs into Bitrix modules and events without core edits

Outcome

Predictable commerce-contour operation and fast incident triage where downtime equals money.

Bitrix24: CRM platform, customs & internal apps

Bitrix24 · PHP · REST · CRM · Business processes · Cursor

PHP/REST CRM custom on Bitrix24: fields, links, UI, business-process logic moved to backend, a line of local and market apps with code review.

Challenge

Needed CRM-process and Bitrix24-app development with quality control — not card configuration.

Solution

  • Portal customs: fields, entity links, UI logic on internal and client rollouts
  • Heavy business-process logic migrated to PHP; reports and portal API refactoring
  • Local/market apps: onboarding, SLA, task helper, company check and related
  • App scoping/shipping with AI speed-up and mandatory human review
  • PHP 8.x upgrades, custom-code resilience, memory-degradation guards

Outcome

A working CRM platform and app line used by the team — with controlled delivery quality.

Bitrix Framework: modules, components, D7 & legacy without core edits

PHP 8 · D7 / ORM · Highload-блоки · Компоненты 2.0 · События · MySQL

Bitrix Framework at engineering depth: modules and components, D7/ORM, HL-blocks, events and agents, legacy work without core modification.

Challenge

Production almost always means legacy without perfect docs. The job is to extend the platform correctly — not by editing the core.

Solution

  • Custom modules and components 2.0 for product and integration scenarios
  • D7/ORM, Highload blocks, programmatic infoblocks and properties
  • Events and agents instead of core hacks; careful init/result_modifier refactoring
  • SQL diagnostics (JOIN/load) next to application code
  • Owning old and new APIs in one contour

Outcome

Extensible custom code that survives platform upgrades and is reviewable by the team.

AI delivery: Cursor conveyor, agents & handoff

Cursor · Plans · Portal handoff · GitLab · Smoke tests · Bitrix24

Repeatable AI-assisted delivery: Cursor pipeline, plans and registry, portal handoff, support/sales agents, apps with mandatory human review.

Challenge

Without an auditable process and review, AI creates chaos and production risk. Needed a controlled delivery contour.

Solution

  • Delivery pipeline: implementation plans, project registry, portal handoff and forms
  • Stage stands (nginx/Apache/PHP-FPM), smoke tests, code-review cycles
  • Agents and scenarios for real roles (support, sales, deals and proposals)
  • Portal ↔ git ↔ pipeline linkage — product delivery, not one-off prompts
  • Rule: AI accelerates drafts; acceptance, merge and ownership stay human

Outcome

A repeatable AI-delivery contour with a traceable plan → code → report trail.
