Building a SaaS product, AI-powered application, or custom business platform? I help startups, founders, agencies, and growing businesses design, build, and scale modern web applications using Next.js, React, Node.js, TypeScript, PostgreSQL, MongoDB, and AI technologies. My focus isn't just writing code. I build software that solves real business problems, automates workflows, improves user experience, and scales as your business grows. Whether you're launching a new MVP, expanding an existing SaaS platform, integrating AI into your product, or improving an existing application, I deliver production-ready solutions that are secure, maintainable, and built for long-term success. ━━━━━━━━━━━━━━━━━━ What I Can Build ━━━━━━━━━━━━━━━━━━ ✔ SaaS Platforms ✔ Startup MVPs ✔ AI-Powered Web Applications ✔ Custom Business Software ✔ Admin Dashboards & Internal Tools ✔ Marketplace Platforms ✔ Booking & Scheduling Systems ✔ Workflow Automation Platforms ✔ Payment & Subscription Systems ━━━━━━━━━━━━━━━━━━ Core Expertise ━━━━━━━━━━━━━━━━━━ Frontend • Next.js • React.js • TypeScript • JavaScript • Tailwind CSS • HTML5 • CSS3 Backend • Node.js • Express.js • REST API Development • Authentication • Authorization • API Development • Webhooks • Background Jobs Databases • PostgreSQL • MongoDB • Supabase • Firebase Cloud & Deployment • Docker • Vercel • Render • Railway • Git • GitHub AI Development • OpenAI API • AI Chatbots • AI Assistants • AI Workflow Automation • Retrieval-Augmented Generation (RAG) • Prompt Engineering • AI Business Applications • LLM Integrations ━━━━━━━━━━━━━━━━━━ Modern AI Development Workflow ━━━━━━━━━━━━━━━━━━ I actively use modern AI-assisted development tools to deliver features faster while maintaining production-quality code.

If you're looking for a developer who understands both technology and business, I'd be happy to help build, improve, or scale your product. Let's discuss your project and build software that's reliable, scalable, and ready for real users.

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.

𝟖+ 𝐲𝐞𝐚𝐫𝐬 | 𝐀𝐈 𝐄𝐧𝐠𝐢𝐧𝐞𝐞𝐫 | 𝐓𝐨𝐩 𝐫𝐚𝐭𝐞𝐝 | 𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐞𝐫 | 𝐍𝐨𝐝𝐞.𝐣𝐬, 𝐑𝐞𝐚𝐜𝐭.𝐣𝐬 | 𝟏𝟎𝟎% 𝐣𝐬𝐬 I build production-ready Web apps, SaaS platforms, internal tools, and ecommerce systems as a Full Stack Developer who owns the entire stack, from database design through deployment on AWS. Over 8+ years, I've delivered SaaS products where I led technical direction end-to-end as a Full Stack Developer. My work typically involves designing backend architecture in Node.js and Express, building scalable APIs, and pairing them with clean React.js, Next.js or Angular frontends. I don't split roles, I architect, build, test and ship complete systems myself. What I focus on as a Full Stack Developer: My day-to-day as a Full Stack Developer means thinking about both layers simultaneously. A robust backend doesn't matter if the frontend can't consume it cleanly. A beautiful interface breaks if the API doesn't scale. So I design backwards from user workflows and forwards from infrastructure constraints. When you hire a Full Stack Developer like me, you're not paying for coverage across two domains, you're getting someone who treats the entire system as one cohesive problem. That changes how I approach every decision, from schema design to component architecture. Core strengths as a Full Stack Developer: I regularly work on Full Stack Developer projects that require: Multi-tenant SaaS architectures with role-based access and permissions Complex internal dashboards and workflow tools for teams Ecommerce platforms and custom Shopify app builds Payment integrations, ledger systems, and financial workflows Third-party API integrations and real-time data sync pipelines AI-powered backend features, not just prompt wrappers, but thoughtful integration into actual product workflows Scalable query logic and database optimization from a Full Stack Developer perspective On the backend side, where most of my time sits as a Full Stack Developer, I design services in Node.js and Express, manage PostgreSQL and MongoDB databases, handle background jobs and async workflows, and deploy everything on AWS infrastructure (EC2, S3, CloudFront, Route 53). TypeScript is standard across my Full Stack Developer work. I approach backend design the way a Full Stack Developer should: not in isolation, but thinking about how frontend code will consume it, how operations teams will monitor it, and how it'll perform under real load. On the frontend side, as part of being a Full Stack Developer, I build interfaces in React.js, Next.js or Angular depending on what the product needs. I prioritize performance, accessibility and maintainability over trendy patterns. Working as a Full Stack Developer on the frontend means understanding that component choices cascade into backend implications.
