Hi, I’m a Senior MERN Stack Developer specializing in React, Next.js, Node.js, Express, MongoDB, and TypeScript.
I work mainly with startups and businesses building SaaS products, web applications, CRMs, dashboards, admin panels, and REST APIs. I can help whether you’re starting something from scratch, adding new features to an existing product, or working with a codebase that needs cleanup and improvement.
At Mammoth-AI, I worked as the Lead Developer on a WhatsApp-based CRM used by 20,000+ active users. I worked across the frontend and backend, including messaging workflows, automation, dashboards, analytics, APIs, and a Chrome extension. This gave me strong hands-on experience with performance, real-time workflows, database optimization, and building applications that can handle growing usage.
I’ve also contributed to Tournated, a sports SaaS platform, working on real-time features, team management, and scalable APIs.
I can help with:
• SaaS applications and MVPs
• MERN & Next.js web applications
• CRM and business management systems
• Dashboards and admin panels
• REST APIs and backend development
• Authentication and role-based systems
• Real-time features and messaging
• MongoDB database design and optimization
• Third-party API and payment integrations
• Bug fixing, refactoring, and performance improvements
• AWS, Vercel, DigitalOcean, Docker and CI/CD
My main stack includes React.js, Next.js, Node.js, Express.js, MongoDB, Mongoose, TypeScript, JavaScript, Redux, Tailwind CSS, REST APIs, Docker and Git.
I care about writing code that is clean, understandable, and easy to maintain. When working on an existing project, I prefer to understand the current architecture first and then make changes without creating more technical debt.
If you’re building a SaaS product, launching an MVP, or improving an existing React/Node.js application, send me the details. I’ll take a look and we can discuss the best way forward.

- Integrate APIs
- Add authentication
- Build and test backend code
- Deploy applications to the cloud

I build and ship working software fast, often in 72 hours. SaaS MVPs, AI receptionists, and lead-response systems, live on a real URL for a fixed price.
Non-technical founders and busy business owners don't need a co-founder or a six-week agency engagement. You need a working product in front of users this week.
What you get with an MVP build:
- A deployed Next.js app on Vercel or your host
- Stripe subscription billing, wired and tested
- A database (Postgres / Supabase)
- The one core flow that makes your product work
- Full source code, transferred to your GitHub
- A handoff walkthrough and one week of bug-fix support
I also build AI receptionists and chatbots that answer, qualify, and book leads 24/7 over web chat and SMS, so businesses stop losing the leads they currently miss. Recent build: LeadsLockAI, an AI lead-response system for home-service businesses that texts missed callers back within 30 seconds, qualifies them, and books the job (Next.js, Supabase, Twilio, Vercel).
Need something smaller? I also build single landing pages, multi-page business websites, and one-off bug fixes, all at flat fixed prices.
I've shipped production SaaS products with Stripe billing, real-time dashboards, multi-tenant platforms, AI chatbots, and automation tools across Next.js, React, FastAPI, Flask, and Node. I move fast with modern tooling without cutting corners on auth, payments, or data.
Not sure where to start? Book a 297 dollar audit: a 24-hour technical review and build plan that credits toward a full build.
Tell me what you're building and I'll tell you exactly how I'd ship it.
