I help businesses maintain and scale existing Laravel/PHP platforms and internal systems (15+ years in web development).
Best fit: long-term development & technical ownership (3+ month engagements), not one-off tasks.
Core areas: feature development, production support, performance optimization, refactoring, legacy modernization, API integrations.
I work with a small in-house team (backend, frontend, QA) to provide reliable long-term support when needed.
Recent relevant work:
- Maintenance and modernization of legacy internal systems (stability, speed, technical debt reduction)
- PIM / product data platforms managing 300,000+ SKUs with complex workflows
- Complex multi-tenant SaaS platforms with admin dashboards, permissions, and background processing
- AI-powered SaaS features (automation, intelligent search, data enrichment)
- Enterprise integrations (Shopify, SAP, Salesforce, Stripe, internal APIs)
Tech stack: PHP (Laravel/Symfony), Vue/React, SQL/MySQL/PostgreSQL/NoSQL, AWS, queues & background workers.
Selected outcomes:
- Page load time improved by 45% (2.2s โ 1.2s)
- API response time reduced from 300ms to under 150ms
- Uptime improved to 99.99% for business-critical platforms
- Automated test coverage increased to 90%+
Security & compliance awareness: encryption in transit/at rest, GDPR-ready systems, secure payment workflows (PCI principles).
If you have an existing Laravel/PHP system that needs long-term ownership and steady development, letโs discuss your roadmap.
