I’m a full-stack web developer, scraper and AI engineer with over 6 years of experience building scalable, production-ready web applications and SaaS platforms. I specialize in modern frontend frameworks like React and Next.js, and backend systems using FastAPI, Node.js, and NestJS.
I design and build secure APIs, multi-tenant SaaS architectures, background workers, and automation systems with clean data flows and strong performance. My work often includes user authentication, subscriptions, dashboards, role-based access, and real-time features.

FAQ
What do you need from me to get started?
Just a clear idea of your project (or a rough one, we will refine it together). If you have wireframes, Figma/XD designs, feature lists, or sample sites you like, send those too.
Can you build the full app from scratch?
Yes, I handle complete full-stack development. I can build the frontend with React or Next.js and the backend using Node.js, Flask, or Django, along with database setup and API integration.
Do you build AI tools or agents using LangChain or OpenAI?
Yes. I can set up LangChain or LangGraph agents connected to GPT, Claude, or Mistral via APIs, including memory, tools, and custom workflows.
Will the app be mobile responsive?
Absolutely. I use Tailwind CSS to create clean, responsive UIs that work across all devices, including mobile, tablet, and desktop.
Can you connect Stripe or other third-party APIs?
Yes. I can integrate payment gateways like Stripe and connect any third-party service that offers an API, including CRMs, email services, or databases.
Do you provide deployment support?
Yes. I can deploy your project to services like Vercel, Render, Railway, or your own VPS using Docker or FastAPI servers.
Can you work on an existing project or only new builds?
I can do both. If you have an existing project, I can audit it, fix bugs, or add new features as needed.

I hired Masab to scrape product data, expecting a basic script that would output a JSON file and call it done. What I got instead was a full production-grade FastAPI backend service with SQLite persistence, REST endpoints, and APScheduler-driven automatic re-scraping every 6 hours. the real surprise...
