"Our Laravel API went from 1.2 seconds to under 200ms – game changer." – SaaS Founder, USA

Senior PHP / Node / Laravel & Full Stack Developer with 10+ years of experience building scalable SaaS platforms, multi-tenant systems, and high-performance APIs. I specialize in modernizing complex systems and delivering production-ready applications using Laravel, Vue.js, React, and Symfony.

Whether you need a full-stack Laravel Vue platform, a decoupled React + Node.js API ecosystem, or a technical partner to rescue and refactor a legacy application, I build systems that remain fast, stable, and profitable as your business scales.

WHAT I ACTUALLY DELIVER:
SaaS & Multi-Tenant Architecture: End-to-end platform development with role-based access, automated background queues, and subscription logic.

API Design & Integration: RESTful & GraphQL APIs built in Laravel and Node.js – clean, documented, and ready for React, Vue, or mobile consumers.

Legacy Modernization & Refactoring: Upgrading outdated systems (e.g., migrating legacy PHP/Symfony to modern architecture) with zero downtime and full automated test coverage.

Data Pipelines & Internal Tools: Building structured data submission forms, moderation workflows, and robust admin panels using Filament and Livewire.

Performance & Infrastructure: Database query tuning, Redis caching, Laravel Octane integration, and modern VPS/AWS deployment pipelines.

Payments & Billing: Deep integration of Stripe subscriptions, custom pricing models, and secure invoicing workflows.

RECENT CLIENT WINS:
Led a major legacy modernization for a high-volume financial platform, successfully upgrading the core architecture from Symfony 3 to Symfony 6 while introducing comprehensive PHPUnit testing.

Architected scalable backend systems and operational dashboards for a complete business management SaaS, streamlining their onboarding flows and subscription logic.

Built robust data processing pipelines and moderation tools for a high-traffic, large-scale reporting platform handling massive amounts of structured user submissions.

Cut server costs and improved response times by optimizing MySQL queries, implementing Redis caching, and setting up automated deployment pipelines on fresh VPS infrastructure.
