Senior Full-Stack Engineer | AI-Generated Code Audit | SaaS

🚀 I help startups, construction teams, and growing businesses build AI-powered SaaS platforms, internal business tools, and modern web applications that are secure, scalable, and built for real-world operations. With 10+ years in software engineering, I bring deep backend expertise, modern full-stack development, system architecture, and technical leadership. I’ve led distributed engineering teams, modernized legacy platforms, built secure APIs, designed database systems, and delivered production software across healthcare, enterprise, and high-compliance environments. My focus includes: • AI-powered SaaS products • Custom web applications and internal platforms • React / Next.js frontends with scalable backend systems • Node.js and PHP APIs • Supabase-backed applications and data-driven tools • AI assistants, agents, and workflow automation systems • Construction and compliance-sensitive platforms • Legacy modernization and platform rebuilds 💡 I help clients with more than coding alone. I help shape the product, design the architecture, build the right foundation, and ensure the system can scale without becoming fragile or expensive to maintain. What I build • AI-powered SaaS MVPs and production platforms • Internal dashboards and operational tools • Secure APIs and backend systems • Workflow automation platforms • Admin systems and business process tools • Healthcare and compliance-aware software • Full-stack platforms with Next.js, React, Node.js, and modern cloud tooling AI development 🤖 I build intelligent software that reduces manual work, improves decision-making, and helps businesses launch new AI-driven capabilities faster. This includes: • OpenAI/Anthropic integrations • AI agents and internal copilots • Document and knowledge workflows • AI-assisted dashboards • Automation pipelines • Custom AI features integrated into existing software • OpenClaw setup and AI workflow implementation Core stack • Frontend: React, Next.js, TypeScript • Backend: Node.js, Django, PHP, Laravel • Database: Supabase, MySQL, PostgreSQL • Infrastructure: Docker, Kubernetes, AWS, Azure, CI/CD • Additional strengths: API architecture, database optimization, DevOps, system modernization, team leadership 🌟 What makes me different is that I combine modern product development with decades of engineering depth. I’ve worked on mission-critical healthcare systems, enterprise platforms, and complex legacy environments, so I understand how to build software that is not only functional, but stable, maintainable, and ready for long-term growth. 📩 If you need an engineer who can help you build an AI SaaS product, modernize an existing platform, or create a secure full-stack system with strong architecture behind it, I’d be happy to discuss your project.
