Case studies
Case studies — deliveries with numbers
Three anonymised projects with concrete metrics: e-commerce integrations, modernization of a critical PHP system and a CRM application with a client portal. Scope, solution, outcome — no marketing fog.
We only show projects whose results can be measured. Every case study describes the starting point, the technical solution and before/after metrics — anonymised in line with client agreements. If you are after a similar outcome in your project, get in touch — I reply within 24 hours.
Omnichannel Sales Integration
A PrestaShop store selling on Allegro and Amazon. Order idempotency, retry queues, stock buffers and drift alerts. Zero duplicates, 15 hours of work saved every week.
PHP Application Modernization
A critical PHP 5.6 system (EOL since 2018) with no tests, no backups and FTP deployments. Audit with PHPStan and PHPCompatibility, characterization tests, module-by-module refactoring with Rector, GitHub Actions CI/CD and monitoring. PHP 5.6 → 8.4 migration without downtime: zero incidents in 12 months, deployments from 2 weeks to 2 days.
CRM and Client Portal
Scattered spreadsheets replaced with a role-based application, approval workflows and reporting. Full audit trail, customer satisfaction up 35%.
