Top Rated Full-Stack Developer specializing in Next.js, Supabase, and AI-powered web applications. I build products that are fast, scalable, and ready to grow with your business. Over the past several years, I've helped startups and growing businesses turn complex ideas into polished, production-ready apps — using modern tools like Next.js, Supabase, PostgreSQL, and AI automation that actually make a difference to your bottom line. Whether you need a customer-facing SaaS platform, an internal dashboard, or an intelligent workflow built on GPT or Claude, I know how to get it shipped cleanly and on time. Here's what working with me looks like in practice: You get a codebase that won't fight you later. I build with TypeScript and clean architecture patterns so your team can maintain and extend the app without needing a full rewrite six months down the line. You get real-time features without the complexity headache. Supabase is one of my core tools — I use it to handle authentication, row-level security, and live data so you're not stitching together five different services. You get AI that's actually integrated, not bolted on. I've connected GPT-4, Claude, and custom ML models into full-stack apps — from document processing pipelines to smart search, recommendation engines, and automated workflows that save teams hours every week. You get a developer who communicates. No ghosting, no vague updates. I write clear documentation, send regular progress notes, and flag issues early rather than late. What I work with: → Frontend: Next.js (App Router), React, Tailwind CSS, TypeScript → Backend: Node.js, Express, REST & tRPC APIs, MERN Stack → Database: PostgreSQL, Supabase, MongoDB, Prisma ORM → AI & Automation: OpenAI, Anthropic Claude, LangChain, n8n, Zapier integrations → DevOps: Vercel, Railway, Docker, CI/CD pipelines Whether you're launching your first product or scaling an existing one, I bring the same level of care and precision to every project. As a Top Rated freelancer, my clients know they're getting someone who shows up, delivers, and treats their budget like it matters. Ready to build something great? Click "Hire Now" or send me a message — I typically respond within a few hours and am happy to jump on a quick call to talk through your project.

I build SaaS products, AI-powered applications and business systems that are designed to work reliably in production not just look good in a demo. Give me something meaningful to build, and I will work to turn it into a reliable product that works for your business, not just a collection of features. You have my word. If you send me an invitation or message, I will take the time to understand what you are building and can share a personalized Loom walkthrough of how I would approach it. Over the past 4+ years, I have contributed to 100+ websites, SaaS platforms, backend APIs, and web & mobile applications for startups and growing businesses across healthcare, education, AI integration, automation and internal business systems. Building software is not usually the difficult part. The decisions made before development starts are often what determine whether a product stays maintainable six months later. That's where I try to add the most value. I work with founders and growing businesses to design and build SaaS products, AI-powered applications, backend systems and business automation that solve real operational problems, not just deliver features. Before writing code, I like to understand how users move through the product, how data flows between services, where responsibilities belong, and which technical decisions will become expensive to change later. That approach helps me build software that is easier to maintain, easier to extend, and less painful to scale. ### What I usually build ⦿ SaaS Platforms & MVPs ⦿ AI-Powered Applications & AI Integrations ⦿ Backend APIs & System Architecture ⦿ Multi-Tenant Architectures | Multi-Tenant SaaS Systems ⦿ Authentication & Role-Based Permissions ⦿ Business Workflow Automation ⦿ Internal Dashboards & Admin Portals ⦿ API & Third-Party Integrations ⦿ AI Integration & Automation: OpenAI API, AI-powered features, custom API development ⦿ Mobile Apps: React Native (iOS & Android), Redux, Expo, Firebase, API Integrations ⦿ Automation Flows: Zapier, n8n, Make, API integrations, AI workflows ⦿ Full Stack Development: MERN Stack, Next.js, Nest.js React.js, Node.js, Express.js, MongoDB, MySQL, Prisma, Wordpress & more ⦿ Performance Optimization, Refactoring.

If you are building a SaaS product, AI-powered application, automation system or modern web platform and want an engineer who can think through both the product and the technical side, I would be happy to learn what you are building. Send me an invitation or message, and I will take the time to understand the problem before suggesting an approach.
