AI Full Stack Engineer | Next.js, Python, Node.js, PostgreSQL, LLMs

I build production-ready AI applications, SaaS platforms, business management systems, and custom web & mobile applications for startups, businesses, and professional-service companies. My advantage is that I don't just integrate AI into an application, I understand how AI, business workflows, and software architecture need to work together to create reliable products. I have experience building SaaS platforms, dashboards, client portals, healthcare applications, workflow management systems, payment solutions, and AI-powered business tools. ### What I can build for you: • AI-powered SaaS applications • AI integrations and LLM-powered features • AI automation and intelligent business workflows • SaaS and multi-tenant platforms • Custom web and mobile applications • Business management, CRM, and ERP systems • Admin, client, and executive dashboards • Construction and project management platforms • Healthcare and telemedicine applications • Document and workflow management systems • REST APIs and scalable backend systems • Payment and subscription systems • Google Workspace integrations • Third-party API integrations • Database architecture and optimization • Cloud deployment and production infrastructure My core technology stack: - Frontend: Next.js, React, React Native, TypeScript, JavaScript, Tailwind CSS - Backend: Node.js, Express, NestJS, Python, Django, REST APIs - Database: PostgreSQL, Prisma, Supabase - AI & Automation: AI APIs, LLM integrations, AI-powered workflows, n8n, third-party AI services - Integrations: Stripe, Paystack, Flutterwave, Google Workspace, cloud APIs, REST APIs - Infrastructure: Docker, VPS, Vercel, Hostinger, AWS, Google Cloud, and cloud-based deployments I also bring a project management and software delivery background, which allows me to work beyond writing code. I can translate business requirements into technical specifications, design the architecture, break development into milestones, manage scope, communicate with stakeholders, integrate third-party services, test features, and take products through deployment. My typical approach is: Requirements → Architecture → AI Strategy → Development → Integration → QA → Deployment → Support Whether you're building a new AI SaaS product adding AI capabilities to an existing platform, automating manual business processes, or developing a complete web/mobile application, I can help turn the business requirement into a scalable, production-ready solution.
