I ship production AI that runs in front of real users and real traffic not prototypes that look good in a demo and fall over in week one. Voice agents, multi-agent systems, and LLM apps, built end to end with the backend and infrastructure to hold up at scale. I am a Senior AI Engineer with of hands-on experience shipping AI that runs reliably in the real world. If you have an idea for an AI agent, chatbot, or LLM feature and you want it built the right way tested, scalable, and ready for real users that's what I do. WHAT I DO BEST AGENTIC AI & MULTI-AGENT SYSTEMS This is my main focus.

Full Stack Developer specializing in QuickBooks integrations, API development, AI automation, Airtable solutions, and GoHighLevel CRM automation. I build production-ready applications and business systems using .NET, C#, Angular, React, SQL Server, PostgreSQL, MongoDB, AWS, OpenAI, Airtable, and GoHighLevel. My experience includes QuickBooks Online/Desktop integrations, custom API development, financial automation, inventory management, shipping integrations, CRM implementations, lead management workflows, marketing automation, and custom business platforms. I have developed solutions that connect multiple third-party services, automate complex business processes, synchronize data across systems, and eliminate repetitive manual tasks. With Airtable, I design scalable databases, custom interfaces, workflow automations, API integrations, reporting dashboards, and operational management systems. With GoHighLevel, I build and optimize CRM pipelines, lead nurturing campaigns, appointment booking systems, automated follow-ups, email and SMS workflows, client onboarding processes, and multi-platform integrations. I focus on scalable architecture, clean and maintainable code, reliable API integrations, and intelligent automation solutions that improve operational efficiency, increase productivity, and help businesses scale with confidence.

I build backend systems, APIs, and custom business logic that power real-world products, platforms, and business operations. With 9+ years of experience as a PHP/Laravel Backend Developer, I focus on building reliable, scalable, and maintainable systems—not just writing code. A large part of my work revolves around Laravel, PHP, REST APIs, databases, integrations, and complex backend workflows. I work with businesses that need custom applications built from the ground up, as well as teams dealing with legacy systems, performance issues, technical debt, or unreliable integrations. Here’s the kind of work I typically take ownership of: ✔ Laravel backend systems and custom application development ✔ PHP 8.x development and clean, maintainable backend architecture ✔ REST API development and third-party API integrations ✔ Authentication, authorization, roles, permissions, and secure API design ✔ Payment gateway integrations and subscription/payment workflows ✔ CRM, ERP, LMS, and other business-system integrations ✔ MySQL, PostgreSQL, SQL Server, and complex database design/query optimization ✔ Webhooks, queues, background jobs, scheduled tasks, and event-driven workflows ✔ Business automation and complex custom business logic ✔ Performance optimization, debugging, refactoring, and legacy-system modernization ✔ AWS/Azure deployments, Linux servers, Nginx/Apache, and production troubleshooting ✔ Docker, Composer, Git, CI/CD, and modern development workflows ✔ Scalable backend architecture for web and mobile applications I’m comfortable working inside existing codebases, understanding complex business requirements, and improving systems without unnecessarily rewriting everything. At the same time, I’m equally comfortable starting from scratch and designing a clean backend architecture from day one. My approach is straightforward: understand the business problem first, keep the architecture practical, write secure and maintainable code, and build systems that can handle growth. If your project involves Laravel, PHP, APIs, databases, payment systems, third-party integrations, complex backend workflows, or an existing system that needs to be stabilized and improved, send me a quick overview of what you’re building—or what’s currently not working—and I’ll provide a practical direction on the best way forward.
