Professional Software Engineer with 6+ years of experience building high-performance digital products. While my roots are in HTML5 & Vanilla JS, I specialize in the modern Node.js ecosystem, crafting scalable backends with Nest.JS and SEO-optimized frontends with Next.js & React.
I prioritize security by implementing robust authentication, data encryption, and protection against OWASP vulnerabilities. I help startups and global businesses launch robust, future-proof applications that are as secure as they are fast. Let’s build something exceptional!
My Portfolio
FAQ
Can you migrate my existing website to Next.js or React?
Absolutely. I can take your current site (whether it's in HTML/CSS, WordPress, or an older JS framework) and rebuild it using Next.js to significantly improve its performance, SEO, and scalability. I ensure all your existing data is safely migrated without any downtime.
How do you ensure the security of my application?
Security is my top priority. I follow OWASP guidelines and implement robust authentication using JWT (JSON Web Tokens) or NextAuth. On the backend with NestJS, I use Bcrypt for data encryption, guard against SQL injection, and implement secure CORS policies to protect your users' data.
Will the application be SEO-friendly and fast?
Yes. By using Next.js, I leverage Server-Side Rendering (SSR) and Static Site Generation (SSG), which are critical for Google indexing. I also optimize images, minimize code, and ensure your app achieves a 90+ Lighthouse score for maximum speed and search visibility.
Do you provide the UI design or work from my files?
I can do both! I am highly skilled at converting Figma, Adobe XD, or Sketch files into pixel-perfect, responsive React components. If you don't have a design yet, I can build a modern, professional UI using Tailwind CSS that aligns with your brand’s goals.
. What happens if I find a bug after the project is finished?
I believe in building long-term relationships. I offer a support period after delivery to fix any bugs or technical issues related to my code. My goal is to ensure your application runs smoothly and that you are 100% satisfied with the final product.
What does a custom website mean?
A custom website is a platform that is created from scratch according to your needs. All successful businesses need some form of online presence, which a custom website can provide. Custom website development has your interests in mind, tailoring each page to your needs.

Just wanted to say you did an amazing job with the fixes! The site is way faster now, the broken links are all sorted, and the forms work flawlessly. It looks great on mobile too, and everything feels really smooth especially the popups and carousel. Honestly, I couldn’t be happier with the result....

Great interaction with Mradul. He’s incredibly responsive, and highly professional. The quality of the work is top-tier, and even though I have been sidetracked on completion of this project, he agreed to work with me to finish the job outside of the Fivrr timeline. I would work with him again in a heartbeat
