I will build a secure full stack web application using mern nextjs or python flask
Omar Malik
About this gig
Are you building a product that needs to be both powerful and secure not one or the other?
I'm a Senior Full Stack Developer and Cybersecurity Specialist with hands-on experience building production-grade web applications using MERN Stack, Next.js, and Python Flask with real AI integration, not just wrappers. What sets my work apart is that every application I build is also hardened against real-world attacks. My security background means your codebase is vetted against the OWASP Top 10 from day one not patched after deployment.
What I can build for you:
Full stack web apps (MERN, Next.js, Python Flask)
AI-powered features using OpenAI, Gemini, or custom pipelines
Secure REST APIs with JWT authentication and RBAC
Database-driven applications (MongoDB, PostgreSQL, Redis)
SaaS dashboards with admin panels and audit logs
Production deployment on Vercel, Railway, or your own VPS
Recent work includes an AI-driven SEO auditor (Next.js + Gemini + Redis + Puppeteer) and a secure document portal with AES-256 encryption, 2FA, and full audit logging.
Before we start, I'll ask a few scoping questions to give you an accurate timeline and quote. For custom projects, feel free to send a message.

FAQ
What do you need from me to get started?
A clear description of your project goals, any design references or wireframes you have, your preferred tech stack (if any), and access credentials for third-party services you want integrated. I'll send a short requirements questionnaire after you place an order.
Can you handle larger or more complex projects?
Absolutely. My packages are starting points. Send me a message with your project details and I'll put together a custom offer with a realistic timeline and scope.
What does "OWASP-hardened" mean in practice?
It means your code is reviewed and built to prevent the top 10 most critical web security risks, including SQL injection, XSS, broken authentication, insecure data exposure, and more. As a penetration tester, I know exactly what attackers look for.
Will the app be deployed and ready to use?
Standard and Premium packages include deployment to a production environment (Vercel, Railway, or a server of your choice). I'll hand over the live URL and all source code.
Do you provide ongoing support after delivery?
I offer 3 days of free post-delivery revisions on all packages. For ongoing maintenance or feature additions, we can discuss a separate arrangement.
