I build and fix backend-heavy business systems with Laravel, APIs, automation, and AI.

I focus on SaaS products, internal tools, CRM/ERP workflows, API integrations, data pipelines, and existing systems that need debugging, refactoring, or production hardening.

I can help with:

- Laravel backend development, debugging, upgrades, and refactoring
- REST API and third-party integrations
- Multi-tenant SaaS architecture and role/permission systems
- Redis queues, background jobs, caching, and performance optimization
- AI/LLM integrations using OpenAI, Gemini, vector search, and structured extraction
- Internal dashboards and admin systems with Laravel + Filament
- Data ingestion and processing with Laravel + Python
- MySQL/PostgreSQL schema design, migrations, and query optimization
- Docker, Ubuntu deployment, Cloudflare, and production troubleshooting

I am comfortable joining existing codebases, identifying architectural or implementation problems, and fixing them without unnecessarily rebuilding the entire system.

Recent systems I have worked on include multi-tenant AI-enabled business platforms, business-directory ingestion and search platforms, internal corporate dashboards, CRM/project-management SaaS products, and third-party API or marketing-platform integrations.

My background in digital operations and product delivery helps me understand the business workflow behind the code. That is especially useful for CRM, internal tools, automation, reporting, and operational systems where the real requirement is often more complex than the initial feature request.

Core stack: Laravel, PHP, PostgreSQL, MySQL, Redis, Python, Docker, REST APIs, Filament, Tailwind CSS, React, OpenAI API, Gemini API.

Available for focused tasks such as bug fixes, migrations, API issues, and deployment problems, as well as larger SaaS and internal-system projects.
