Ex-CTO AI & Backend Engineer | Full-Stack, APIs, MVPs

I help businesses integrate AI into existing software — without breaking the backend. I also build, fix, and scale serious development projects: SaaS platforms, MVPs, backend APIs, dashboards, databases, payment systems, admin panels, integrations, and production deployments. Most companies do not need another AI demo. They need software that works inside their real business: connected to their database, users, permissions, payment flow, CRM, admin panel, documents, APIs, and workflows. I help SaaS, eCommerce, and startup teams build and improve production software, including: AI & automation AI chatbots connected to business data RAG systems for documents, knowledge bases, and internal tools OpenAI, Claude, Gemini, LangChain, and vector database integrations AI-powered dashboards, search, reporting, and support tools Workflow automation using AI and backend APIs Backend systems for AI SaaS products Backend & product development SaaS MVPs and custom web applications Backend APIs using Node.js, TypeScript, Python, PHP/Laravel, CodeIgniter, and .NET Admin panels, dashboards, customer portals, and internal tools REST/GraphQL APIs, webhooks, and third-party integrations Auth systems, permissions, Stripe/payment flows, and secure API integrations PostgreSQL, MySQL, MongoDB, query optimization, and database design AWS, Docker, CI/CD, monitoring, and production deployment I’m a senior backend engineer and former CTO with 8+ years of experience across Node.js, TypeScript, Python, PHP/Laravel, CodeIgniter, .NET, PostgreSQL, MySQL, MongoDB, AWS, Docker, CI/CD, APIs, payments, and production infrastructure. Where I’m especially useful: You already have a product and want to add AI You need a SaaS MVP or custom web application built properly Your AI prototype works locally but is not production-ready Your backend is messy and needs a senior engineer to stabilize it You need AI connected securely to real business data You need someone who can make backend decisions, not just complete tickets Real problems I’ve solved: Fixed Stripe webhook race conditions causing checkout failures Reduced database queries from 30+ seconds to under 100ms Cut AWS costs by 40% with better architecture Migrated legacy PHP/Python systems without downtime Stabilized systems that worked locally but failed in production My development style: No cowboy coding I understand the system before changing it I prefer safe, incremental improvements over risky rewrites I document important decisions so you are not dependent on one developer I build with production, security, maintainability, and cost in mind If you need AI integrated into a real business system — or you need a backend, SaaS product, MVP, or full-stack application that can actually scale — I can help.
