I work on Laravel and React applications, mainly SaaS products and data-heavy systems that need to stay stable as they grow.
This includes building new products from scratch, improving existing codebases, and fixing systems that started simple but became difficult to maintain over time.
Typical problems I’m brought in for:
• Backend logic that has become hard to extend or reason about
• Multi-tenant applications where data separation is not clearly defined
• Performance issues once real users and data are added
• Authentication and role systems that no longer fit the product
• MVPs that worked early on but struggle in production
My approach is straightforward:
I keep the backend structure clean, separate business logic properly, and avoid shortcuts that create long-term issues later. Where products handle billing or subscriptions, I’m careful with calculations and data consistency. On the frontend, I focus on clear, maintainable React or
Next.js code that integrates cleanly with the API.
I’ve worked on:
• Laravel and PHP applications of varying size and age
• SaaS platforms, including multi-tenant setups
• Systems with subscriptions, billing, and reporting
• Legacy projects that needed modernization without breaking production
• APIs that had to perform reliably under real usage
Main technologies I work with:
Laravel, PHP, React, Next.js, TypeScript, Tailwind, REST APIs, role and permission systems, Stripe, and Razorpay when needed
I prefer clear communication, realistic timelines, and writing code that someone else can understand six months later.
