Senior Laravel Developer

I build and evolve Laravel applications

10+ years building Laravel systems in production. Architecture, performance, integrations, and AI integrated at the core.

10 years working with Laravel on real projects: government platforms, B2B SaaS, systems with thousands of active users in production. I build new applications and evolve the ones that already exist.

I don't arrive to rewrite everything from scratch. I arrive to understand what's there and evolve what needs to change.

01

Architecture that scales

I design systems thinking about what comes next, not just what's needed today. Maintainable code, documented decisions, no accumulated technical debt.

02

Speed without sacrificing solidity

20 years of experience means moving fast without improvising. I deliver on time without compromising the quality of the system.

03

AI integrated, not bolted on

When the project justifies it, I integrate language models into the core of the system, not as an external chatbot, but as part of the business logic.

Why Laravel

After 10 years I keep choosing Laravel for the same reasons: a mature and complete ecosystem, code that ages well, development speed that doesn't collapse when the project scales, and a natural integration path for AI through the Laravel AI SDK.

A well-built Laravel application from five years ago is still maintainable today. That's not trivial.

What I build

Multi-tenant SaaS applications

Platforms where each client has isolated data, granular permissions, and independent configuration, built to scale without multiplying infrastructure.

Fullstack applications

End-to-end systems: backend logic, frontend, database, deployment. No handoffs between layers — one person who understands the whole system.

Complex backends and frontends

Applications where the business logic is the hard part. Intricate workflows, complex state, multiple roles, edge cases that need architectural thinking, not just code.

REST APIs

Versioned, authenticated, documented, rate-limited. Built to be consumed by third parties, mobile apps, or decoupled frontends.

RAG systems

Retrieval-augmented generation over proprietary data: documents, databases, knowledge bases. The model answers with the client's own information as context.

Multi-agent workflows

Systems where multiple AI agents with distinct roles, contexts, and autonomy limits collaborate to resolve a task. Each agent knows what it can and can't do.

MCP integrations

Model Context Protocol for connecting AI models to external tools, APIs, and data sources, giving the model real operational reach inside the system.

Selected projects
