You will get a custom full stack web application in Nodejs or FastAPI
Project details
Do you need a robust, scalable, and custom full-stack web application? I am here to build it.
I am a Full-Stack Software Engineer with experience developing secure web architectures. I combine modern frontend frameworks (React/Next.js) with powerful backend engines (Node.js/Express, FastAPI/Python) and databases (MongoDB, Firebase) to create complete custom web systems.
💻 What I Can Build For You:
• Custom SaaS Applications: Complete platforms with user roles and dashboards.
• Backend API Development: Secure RESTful or GraphQL APIs with JWT auth.
• Database Integration: Fast data reading/writing (MongoDB, Firebase).
• Payment Gateways: Seamless Stripe or PayPal subscription portals.
🛠️ Tech Stack:
• Frontend: Next.js, React, TypeScript, Tailwind CSS
• Backend: Node.js/Express, FastAPI, Python
• Database: MongoDB, Firebase, PostgreSQL
🌟 Why Choose Me?
• Clean, documented, and modular MVC architecture.
• Advanced security practices (password hashing, secure CORS).
• Production-ready deployment setup.
Let's build a powerful web system. (Please contact me first to discuss your technical specifications, database schema, and project goals.)

Full-Stack Software Engineer | React, NextJS & FastAPI Developer
Town Sripur, Bangladesh - 7:53 am local time
I am a Full-Stack Software Engineer and active Software Engineer Intern at Techdojo. I specialize in building fast, secure, and highly optimized web applications using React, NextJS, TypeScript, Tailwind CSS, NodeJS, and FastAPI. My focus is writing pixel-perfect frontend layouts and building robust backend systems that scale smoothly.
💻 Core Services I Provide:
1. 📐 Figma to React / NextJS Conversion
- Converting static design files (Figma, Adobe XD, Sketch, PSD) into interactive, clean code.
- Fully responsive, mobile-first design implementation using Tailwind CSS.
- Semantic HTML markup structure for SEO optimization.
- Interactive animations and UI transitions using Framer Motion.
2. 🔧 React Debugging, API Integration & Speed Optimization
- Debugging complex component rendering, state management glitches, and console errors.
- Integrating external RESTful and GraphQL APIs (Stripe, SendGrid, Firebase, auth gates).
- Performance tuning: lazy loading assets, optimizing image bundles, and achieving a 90+ Lighthouse/PageSpeed score.
3. 🤖 AI & OpenAI API integrations
- Connecting Large Language Models (LLMs) like OpenAI's GPT-4, Claude, and Gemini.
- Building custom conversational AI chatbots with system prompts and chat memory.
- Automating text summarization, data extraction, and content generation pipelines.
4. 💻 Full-Stack SaaS MVP Development
- Building secure, production-ready full-stack applications from scratch.
- Backend routing and controllers using Express and NodeJS or FastAPI and Python.
- Integrating databases (MongoDB, PostgreSQL, Firebase) with secure CRUD operations.
- User authentication implementations (JWT, bcrypt password hashing, session tokens).
