For startups and businesses that need real software fast, I build AI SaaS products that are ready to ship and built to grow. Give me an idea and I'll build it into a product real customers will pay for. That's my promise. If you send me a message or invite me to your job, I'll personally review your project and reply with a Loom video walking through exactly how I'd build it before we start. A little more about me. I build full-stack products for startups that need more than a basic website. Whether it's an AI SaaS MVP, a stuck project that needs rescuing, or a full platform with auth, payments, and dashboards ready on day one, I focus on systems that are clean, maintainable, and ready to scale. Some recent results: → Architected a Next.js and Node.js platform on AWS serving 10,000+ users at 99.9% uptime, with Stripe billing and a full admin dashboard. → Shipped a live AI bill-dispute SaaS with document analysis and role-based access that's serving paying users today. → Built an n8n automation with Twilio and OpenAI that cut a client's response time from hours to under two minutes. What separates me from a lot of freelancers is that I build real production systems, not quick prototypes that fall apart at scale. I ask sharp questions upfront so we avoid scope creep, I communicate daily so you always know where the project stands, and I recommend the architecture that saves you money long-term not the one that pads my hours. I work across the full stack: Next.js, React, and TypeScript on the frontend; Node.js, FastAPI, and Django on the backend; PostgreSQL and Supabase for data; OpenAI, Claude, RAG, and LangGraph for AI; and AWS, Docker, and GitHub Actions for deployment. I integrate Stripe, SendGrid, Twilio, Google APIs, and 400+ tools through n8n. If you're looking for someone who can properly build your product from start to finish or rescue one that's stuck, send me a message and let's talk.

I help SaaS companies build and fix the backend systems that are critical to their product — billing, APIs, and integrations. Most SaaS platforms run into the same issues as they grow: billing logic becomes messy, integrations start breaking, and data stops syncing properly. I focus on solving these problems by building systems that are stable, scalable, and easy to maintain. With 10+ years of experience, I’ve worked on production systems involving payments, affiliate tracking, CRM integrations, and complex API workflows. What I Can Help You With • SaaS backend development (Laravel, Django, Node.js) • API development & integrations (REST, webhooks, third-party services) • Subscription & billing systems (Stripe, usage-based, hybrid models) • Webhook systems & event-driven architecture • Automation and data synchronization across platforms • Debugging and fixing unstable backend systems Experience Highlights • Built and maintained API-driven systems handling real-time data and integrations • Implemented Stripe billing systems including subscriptions, webhooks, and usage tracking • Developed affiliate tracking and commission logic for SaaS platforms • Integrated multiple systems (payments, CRM, third-party APIs) into unified workflows How I Work I focus on clean architecture, reliability, and long-term scalability — not quick fixes. I communicate clearly, think through edge cases, and build systems that won’t break as your product grows. If your SaaS depends on billing, APIs, or multiple systems working together, I can help you build it right or fix what’s already there.

I help founders and businesses turn 𝐀𝐈 𝐒𝐚𝐚𝐒 𝐢𝐝𝐞𝐚𝐬 into 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧-𝐫𝐞𝐚𝐝𝐲 products, not prototypes, not demos, but scalable applications used by real customers. After 120+ founder conversations, one thing is clear, most teams spend months building features before validating what users actually need. In many cases, this leads to delayed launches, wasted development budgets, and products that never gain traction. The issue isn't the idea, it's building too much before proving what works. Most SaaS projects fail because they try to launch everything at once, I don't. I focus on identifying the core value, shipping an MVP fast, and scaling it into a production-ready product. Most teams overbuild early. I focus on getting products in users' hands early. 📊 𝐖𝐡𝐚𝐭 𝐓𝐡𝐢𝐬 𝐋𝐨𝐨𝐤𝐬 𝐋𝐢𝐤𝐞 𝐢𝐧 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞 Built AI SaaS products from idea to launch in 4–6 weeks Developed AI-powered platforms serving real users and customers Integrated LLMs to power intelligent product experiences Designed scalable architectures that support growth beyond MVP stage Delivered production-ready systems focused on speed, reliability, and usability 🤖 𝐀𝐈 𝐒𝐚𝐚𝐒 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 AI SaaS development (LLM-powered platforms) SaaS MVP development for startups and founders AI Agent development OpenAI, Claude, and Gemini integrations RAG-powered applications AI features inside existing SaaS products Multi-tenant SaaS applications Custom AI-powered products ⚙️ 𝐏𝐫𝐨𝐝𝐮𝐜𝐭 & 𝐏𝐥𝐚𝐭𝐟𝐨𝐫𝐦 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 Full-stack SaaS development Web application development Dashboard and admin portal development SaaS architecture and system design Authentication, user management, and permissions Product validation and MVP execution 🧠 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 & 𝐁𝐚𝐜𝐤𝐞𝐧𝐝 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫𝐢𝐧𝐠 Full-stack development (React, Next.js, Node.js) Backend development using NestJS & Express REST API development & integrations Scalable architecture and database design PostgreSQL, MongoDB, and Supabase Performance-focused backend systems 💳 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧𝐬 & 𝐒𝐚𝐚𝐒 𝐒𝐲𝐬𝐭𝐞𝐦𝐬 Stripe integration & subscription systems Usage-based billing implementation Payment gateway integrations Third-party API integrations CRM and external platform integrations 🧰 𝐓𝐞𝐜𝐡 𝐒𝐭𝐚𝐜𝐤 𝐅𝐫𝐨𝐧𝐭𝐞𝐧𝐝: React.js, Next.js, TypeScript, Tailwind CSS, ShadCN UI 𝐁𝐚𝐜𝐤𝐞𝐧𝐝: Node.js, NestJS, Express.js, Python, FastAPI 𝐀𝐈 𝐌𝐨𝐝𝐞𝐥𝐬: OpenAI (GPT-4o), Claude, Gemini, Llama, DeepSeek, Mistral 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭𝐬 & 𝐅𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤𝐬: LangChain, LangGraph, OpenAI Agents SDK, CrewAI, AutoGen, Vercel AI SDK, MCP 𝐑𝐀𝐆 & 𝐕𝐞𝐜𝐭𝐨𝐫 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞𝐬: Pinecone, Weaviate, Qdrant, ChromaDB, Semantic Search, Embeddings 𝐃𝐚𝐭𝐚𝐛𝐚𝐬𝐞𝐬: PostgreSQL, MongoDB, Supabase, Redis 𝐒𝐚𝐚𝐒 𝐒𝐲𝐬𝐭𝐞𝐦𝐬: Stripe Billing, Subscription Management, Multi-Tenant Architecture, Authentication, RBAC, Webhooks 𝐂𝐥𝐨𝐮𝐝 & 𝐃𝐞𝐯𝐎𝐩𝐬: AWS, Vercel, Docker, CI/CD, GitHub Actions 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧𝐬: REST APIs, GraphQL, Third-Party APIs, CRM Integrations 🎯 𝐖𝐡𝐞𝐫𝐞 𝐈 𝐅𝐢𝐭 𝐁𝐞𝐬𝐭 Founders building AI SaaS products Startups launching MVPs quickly Teams adding AI capabilities to existing products Companies building AI-powered customer experiences Businesses looking for scalable SaaS architecture from day one 🤝 𝐖𝐡𝐚𝐭 𝐈𝐭’𝐬 𝐋𝐢𝐤𝐞 𝐖𝐨𝐫𝐤𝐢𝐧𝐠 𝐖𝐢𝐭𝐡 𝐌𝐞 Clear scope from day one — no guesswork, no surprises MVPs launched quickly without unnecessary complexity Replies within 30–60 minutes (unless I'm asleep) I'll tell you what NOT to build as much as what to build (believe me, it matters a lot) 🤝 𝐋𝐞𝐭’𝐬 𝐖𝐨𝐫𝐤 𝐓𝐨𝐠𝐞𝐭𝐡𝐞𝐫 If you're serious about building an AI SaaS product, launching an MVP, or adding AI capabilities to your platform, send me a message.
