Problem
The legacy version of the project limited growth: the 1C integration was fragile, the catalog accumulated technical debt, filters were unstable, and desktop and mobile versions evolved as separate products.
When I joined "Refactoring a 1C-Bitrix Project: 1C Integration, Catalog, Filters, Desktop and Mobile", the pattern was familiar: local fixes existed, but there was no shared model connecting business goals to technical execution. That gap kept incidents recurring and manual overhead growing.
I decomposed the issue into controllable layers: input signals, decision rules, handoff points and post-release quality control. This immediately clarified where performance was being lost and why previous fixes did not hold.
Approach and solution
We began with a technical audit and mapping of critical scenarios, then progressively stabilized the integration layer, catalog logic, filters, and interface layers. This approach minimized the risk of disrupting business processes.
Instead of patching symptoms, I implemented a phased model: acceptance criteria first, minimum viable core second, and scale expansion only after stability was proven. This created measurable progress at each stage.
Operational governance was part of the implementation itself: ownership boundaries, deviation handling and explicit escalation logic. That made the outcome repeatable rather than person-dependent.
Architecture
The refactoring included redesigning the 1C integration, simplifying dependencies within the catalog, normalizing data for filtering, and aligning interface templates between desktop and mobile. The goal was a predictable maintenance system, not just a visual update.
Architecturally, the key principle was "observability before complexity". It allowed the team to see real impact of each change and keep control while scaling.
The stack (1C-Bitrix, 1C Integration, Catalog Logic, Search Filters, Responsive Frontend) was treated as an enabler, not a goal: every decision was evaluated by impact on delivery speed, stability and support cost.
Outcome
The site became more stable and easier to develop: the 1C integration gained a more reliable architecture, the catalog and filters better supported product range growth, and the user experience became device-independent.
Business impact was not limited to isolated metric gains. The team received a practical operating model with clearer priorities, faster decisions and lower regression risk.
I documented outcomes in a before/after format tied to practical KPIs, so leadership could directly map engineering work to commercial value.
Metrics
- Reduced operational risk in 1C integration.
- Improved manageability of catalog and filtering.
- Decreased regressions between desktop and mobile versions.
- Accelerated pace of future enhancements.
- Team response speed to deviations and incidents.
- Manual overhead share before vs after rollout.
- Stability of critical user flow under load.
- Release predictability and regression frequency.
- Input quality: less noise, higher useful outcome.
Deliverables
- Refactoring of 1C integration.
- Catalog restructuring.
- Filter updates.
- Alignment of desktop and mobile versions.
- Target architecture map with implementation priorities.
- Phased rollout plan with acceptance criteria.
- Operational runbook and escalation model.
- Post-release quality checklists.
- 30/60-day optimization backlog.
Unique solution in this case
In this case, the differentiator was component-driven Bitrix domain model, risk-aware traffic filtering with explainable decision rules, AI workflow with safe rollout and quality validation. The delivery was not a one-off patch: architecture constraints were fixed first, then a production workflow was rolled out so the team can scale without losing control.
Comparison: before vs after systems rollout
| Aspect | Before | After |
|---|---|---|
| Delivery model | Local fixes without unified architecture | Systems-first rollout with clear architecture logic |
| Operational control | Manual and context-dependent execution | Transparent rules, checklists and quality control |
| Business impact | The 1C-Bitrix project was hindering growth due to outdated 1C integration, a complex catalog, unstable filters, and desynchronization between desktop and mobile site versions. | A comprehensive refactoring of the Bitrix project was completed: 1C integration was rebuilt, catalog and filter logic updated, and desktop and mobile versions aligned to a consistent standard. |
