I help founders, startups, and growing businesses turn ideas into production-ready SaaS products, MVPs, dashboards, and scalable web applications. Most clients come to me when they need more than just coding. They need someone who can help plan the product, build the right features first, launch quickly, and create a stable technical foundation that supports real users, payments, admin workflows, automation, and future growth. Over the last 6+ years, I’ve worked across the full stack using React, Next.js, Node.js, Express.js, MongoDB, PostgreSQL, TypeScript, REST APIs, authentication systems, payment integrations, and cloud deployments. What I build: • SaaS Platforms • MVP Development • AI-Powered Web Apps • Admin Dashboards • Customer Portals • Subscription Systems • Internal Business Tools • API Integrations • Automation Workflows • Scalable Backend Systems I also specialize in fixing and scaling AI-generated or vibe-coded applications built with tools like Lovable, Bolt, Cursor, Replit, Same.dev, and v0. Many founders quickly discover these tools can generate UI fast — but production stability, architecture, scalability, authentication, payments, security, and maintainability still require an experienced engineer. I help transform those prototypes into clean, scalable, production-ready applications.

The system included: • Security pass applications • Job vacancy management • KPI tracking • Customer review management • Workflow automation This reduced manual operational work by 3+ hours per day and streamlined the company’s daily processes. My approach is business-focused, not just code-focused. Before development starts, I help identify: • What should be built first • Which features can wait • How to reduce unnecessary complexity • How to launch faster • How to structure the product for scaling When the project is complete, you receive: • Clean, maintainable code • Production-ready deployment • Organized project structure • API integrations • Technical documentation • Proper handover support I also provide long-term support for live products, including: • Bug fixing • Performance optimization • New feature development • Deployment support • Refactoring • Technical cleanup • Scaling improvements Tech Stack: React.js • Next.js • Node.js • Express.js • TypeScript • JavaScript • MongoDB • PostgreSQL • Tailwind CSS • REST APIs • Stripe • Authentication • Vercel • Netlify • AWS • Docker • Supabase If you’re building a SaaS product, MVP, startup platform, customer portal, AI-generated prototype, or internal business system, send me a message and I’ll help you find the fastest practical path to launch.
