Most MVPs fail not because the code is bad, but because the wrong things get built. I help startup founders avoid that and ship a launch-ready MVP in 4–8 weeks that users adopt and investors take seriously. I'm Top Rated Plus on Upwork with a 100% Job Success Score, and I've helped founders go from idea → MVP → funding, with apps that have scaled past 100,000 users. What you get when we work together: A structured MVP roadmap (not a feature wishlist) Production-ready iOS + Android apps, built to scale Honest pushback when a feature, framework, or AI integration doesn't earn its place Clear communication designed for non-technical founders 🚀 What I build On-demand platforms (Uber-style), SaaS and productivity tools, marketplaces and e-commerce, fintech and wallet apps, social and content platforms. 🛠 Tech stack React Native, Flutter, Swift, Kotlin, Node.js, Firebase, Supabase, AWS, PostgreSQL, MongoDB, REST and GraphQL APIs. 🤖 On AI I integrate AI when it genuinely improves the product — smart recommendations, chat, automation, voice/text processing. If it doesn't make your MVP better, I'll tell you. 🎯 Best fit Founders at the idea-to-MVP stage, non-technical founders who want a technical partner (not just a coder), and teams launching their first product. 💬 Next step Send me a message with a few sentences about your idea. Within 24 hours, I'll reply with initial thoughts on scope, timeline, and whether I'm the right fit. If I'm not, I'll usually point you to someone who is.

A Full Stack AI Developer who builds production-ready, AI-powered web applications that hold up under real-world use. My work sits at the intersection of Full Stack Developer and AI Developer, pairing modern LLM features with clean React frontends and reliable Node.js & Python backends, so you get one engineer who can own a product end-to-end instead of splitting it across a separate React developer, backend developer, and AI specialist. As an AI Developer, I help founders and teams add intelligence to their products that actually works in production not throwaway demos. I build LLM-powered features, RAG chatbots, AI Automations using tools like N8N, Zapier, Make and Claude and AI agents using the OpenAI and Claude APIs, LangChain, and Custom GPT integrations, with a focus on systems that are reliable, observable, and cost-controlled. Recently I designed and shipped AI automation and Custom GPT workflows that streamlined real business operations, and I supervised the launch of a B2B SaaS AI platform through architecture and code review work my clients rated 5 stars. As a Full Stack Developer, I take ownership of the whole system. My frontend work is React and Next.js with TypeScript and Tailwind CSS; my backend work is Node.js, Express, NestJS and Python, exposing clean REST and GraphQL APIs. This end-to-end ownership is why clients bring me in as a Full Stack AI Developer rather than coordinating three roles. I keep the architecture coherent from database to UI, and I make sure AI features integrate cleanly into the product instead of sitting bolted on the side. A large part of my work involves turning an idea or a rough prototype into a stable, scalable platform: multi-role dashboards, admin panels, subscription and authentication systems, and the API layer that ties LLM and AI agent features into the product. I've built SaaS platforms serving thousands of users and shipped crypto wallets that handle real transactions, so I'm comfortable with the parts of a product where data integrity, security, and performance genuinely matter.

𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤: I think like a product owner, not just a coder. Before writing code, I align on the business outcome who the user is, what they pay for, and where the product needs to be in six months. Then I ship in clear weekly milestones, communicate proactively, and stay available for fast turnaround. The result is a 100% Job Success score and clients who come back for their next build.

With 18+ years of hands-on experience, I specialize in designing and building scalable, secure, and production-grade web & mobile applications for startups, enterprises, and growing businesses. I’ve worked across full product lifecycles, from idea validation and architecture to deployment, scaling, and long-term maintenance. Over the years, I’ve successfully delivered complex SaaS platforms, enterprise dashboards, marketplaces, AI-powered systems, ERP modules, and high-performance web applications. My strength lies in understanding business logic first, then building clean, scalable, and maintainable solutions. I don’t just build features, I help architect long-term products. Core Expertise: Full Stack Development - PHP, Node.js, Laravel, Nest.js, Express.js - React.js, Next.js, Angular, Vue.js - HTML5, CSS3, Tailwind, Bootstrap - TypeScript, JavaScript (ES6+) Database & Architecture - MySQL, PostgreSQL, MongoDB - Redis, Elasticsearch - Multi-tenant SaaS architecture - Microservices & API-first development Cloud - AWS (EC2, S3, Lambda, RDS, CloudFront) - DigitalOcean, VPS deployments - Docker, CI/CD, GitHub Actions - Performance optimization & scaling Mobile Development - React Native - Cross-platform mobile apps - API-driven mobile architectures API & Integration Expertise - REST APIs & GraphQL - Payment Gateways (Stripe, PayPal, etc.) - Third-party SaaS integrations - CRM, ERP, and Accounting integrations - AI & automation integrations Types of Applications I've Built: - SaaS Platforms - CRM & ERP Systems - AI-Powered Applications - Marketplace Platforms - Booking & Scheduling Systems - Financial & Accounting Systems - Real-time Chat Applications - Multi-tenant SaaS Platforms - Analytics Dashboards - Healthcare Platforms - EdTech Platforms - On-Demand Platforms - Property & Rental Platforms - E-commerce Platforms - Enterprise Internal Tools I focus on building production-ready systems, not quick temporary solutions. If you're looking for a senior developer who understands both technology and business, I’d be glad to collaborate.
