Full-Stack Developer | Custom LMS, CRM, SaaS & Web Apps | React, Next.js, Angular, Node.js, .NET + AI Integration

I build fast, scalable web applications from scratch — not templates or plugins. If you need a custom LMS, CRM, SaaS platform, business website, or a web app tailored to exactly how your business works, I turn your idea into a real, working product you fully own.

What I do:

Custom LMS platforms — course sales, student enrollment, live Google Meet classes, AI-powered quizzes, real-time chat, and payment integration (Stripe + manual)
Custom CRM software — lead management, sales pipelines, task automation, analytics dashboards, and AI lead scoring, built around your workflow
SaaS products & web apps — subscription billing, multi-tenant architecture, admin dashboards, REST APIs, and third-party integrations
Business websites & high-converting landing pages
AI integration — connecting your app to AI models (GPT, Claude, Gemini) and returning clean, structured data you can actually use

My tech stack:
Frontend: React, Next.js, Angular, TypeScript, JavaScript
Backend: Node.js, NestJS, Express, .NET, C#
Databases: PostgreSQL, Supabase, Firebase, DynamoDB
Cloud & tools: AWS (Lambda, Cognito), Stripe, WebSocket, Microservices

Selected projects:

Doctor Portal — a healthcare platform with online appointment booking (Next.js, Supabase)
AI Code Builder — an AI-powered development platform with real-time collaboration and Stripe billing (Angular, NestJS, WebSocket, PostgreSQL, Microservices)
LMS Platform — a full learning management system with course management and payments (Angular, C++ Drogon, PostgreSQL, Stripe)
POS System — a point-of-sale platform with real-time updates and payment processing (Next.js, NestJS, PostgreSQL, WebSocket, Stripe)
Booking Platform — a scheduling and reservation system (React, Firebase, Supabase)

Why work with me:

Everything is coded from scratch — clean, scalable, and maintainable, with full source code handed over to you
I test every integration against the real service (real Stripe payments, real AI responses, real APIs) — nothing mocked or faked
Clear communication, realistic timelines, and a focus on solving your actual problem — not just shipping code

I started with React Native, moved through full-stack web development, and now specialize in building AI-integrated applications. Whether you're a startup validating an idea, a business that's outgrown spreadsheets, or a founder ready to launch a SaaS product, I'd love to help you build it.
