Hi, I’m Waleed, an AI engineer and blockchain developer with over 10 years of experience in developing intelligent systems, smart automation tools and decentralized applications. While I may be new on Upwork, my journey with AI started during my undergraduate years, when AI was still emerging as “the next big thing”. I was instantly fascinated by its potential. That curiosity evolved into a career and later, a Master’s degree specializing in Artificial Intelligence. Since then, I’ve worked across a wide range of AI-powered and blockchain-based products, from LLM-based SaaS platforms to multi-agent automation systems and smart contract ecosystems. If you're building something ambitious in the AI or Web3 space, I'm here to bring it to life, reliably, efficiently and with deep technical care.

I build AI tools that automate internal workflows, power new AI products, and replace spreadsheet-based processes with scalable systems. In 2025 alone, I’ve helped clients design, build, and ship 32+ AI applications ranging from internal automation tools to full SaaS MVPs. Many of these systems support HIPAA-sensitive workflows, operational automation, and data-driven decision making. Most clients hire me when they want to: • Build an AI-powered SaaS MVP • Create internal AI tools for their team • Automate a workflow currently handled manually • Add AI capabilities to an existing product or platform Typical systems I build include: • AI dashboards that analyze business or marketing data • automation pipelines that replace manual spreadsheet workflows • internal AI copilots for operations or support teams • AI agents integrated into company tools and CRMs • AI SaaS MVPs for startups launching new products These systems often integrate with tools such as: • OpenAI / Claude • CRMs (HubSpot, Salesforce, GoHighLevel) • internal databases and APIs • automation platforms (Make, n8n, Zapier) • modern web stacks such as Next.js I lead Xpand Technology, an AI automation studio based in Los Angeles focused on building custom AI systems for businesses and startups. Projects typically range from $5k–$20k depending on complexity. Most clients start with a Phase 1 MVP build and then expand the system once the foundation is in place. Typical project structure: Phase 1 – MVP build Phase 2 – automation & integrations Phase 3 – scaling and improvements This approach allows clients to launch quickly, validate their systems, and expand functionality without unnecessary complexity. If you’re looking to build an AI-powered product, automate internal workflows, or turn a complex process into a scalable system, I’d be happy to discuss your project.

Are you building a standard web application, or an intelligent business platform? In today's market, "clean code" is the bare minimum. You need a system that is secure, scalable, and capable of leveraging modern AI to automate your business logic. I am not just a coder; I am a Solutions Architect with over 11 years of experience. I bridge the gap between robust, enterprise-grade engineering (PHP/Laravel/Symfony) and the new world of AI integration. While junior developers rely on AI to write their code, I use my deep architectural expertise to build secure AI agents and workflows directly into your application. I specialize in helping founders and SMEs transition from "legacy" web apps to intelligent, automated platforms without rewriting everything from scratch. How I Help You Win: - AI-Powered SaaS Architecture: I build platforms where AI isn't a gimmick. It’s a core feature. From intelligent admin dashboards (FilamentPHP) to custom RAG (Retrieval-Augmented Generation) systems that "talk" to your database. - Enterprise Reliability: I bring a senior engineer’s discipline to development. I write strict types, optimize complex SQL queries for speed, and ensure your data remains secure—things that "no-code" tools cannot do. - MVP Acceleration: Using modern stacks (TALL stack, Filament, Livewire), I can deliver production-ready MVPs in weeks, not months, allowing you to secure funding or revenue faster. Technical Stack & Expertise: - 🚀 AI & Automation Integration - LLM Integration: OpenAI, Anthropic (Claude), and open-source models. - Intelligent Workflows: Building custom agents that automate data entry, categorization, and content generation. - RAG Implementation: Connecting your private business data to AI safely. backend Backend & Architecture (The Core) - Languages: PHP 8.x, SQL (MySQL/MariaDB). - Frameworks: Laravel (Expert), Symfony, Slim. - Admin Panels: FilamentPHP. Rapidly building internal tools and customer portals. - Database: Complex SQL optimization, Schema Design, Migration strategies. frontend Frontend & UX -Modern Stack: Livewire, Alpine.js, Tailwind CSS (The "TALL" Stack). - JS Frameworks: Vue.js, React (for specific reactive components). 🛠 DevOps & Quality Assurance - Infrastructure: Docker, CI/CD Pipelines (GitHub Actions), Heroku. - Testing: PHPUnit, Pest, Static Analysis (PHPStan). I ensure the code works before you ever see it. Why Work With Me? I have been a Founder & CEO, a CTO, and a Lead Developer. I understand that you aren't paying for code; you are paying for a business result. I communicate clearly, I work autonomously, and I treat your budget with the same respect I treat my own. Ready to upgrade your technology? Click the green "Invite to Job" button. Let’s discuss how we can build a system that works as hard as you do.
