Kunwar Vashistha Narayan Tyagi

👋 Hi, I’m Kunwar

I’m a Senior Full Stack Web Developer with 8.5+ years of professional experience building scalable, high-performance, production-ready web applications.

My primary expertise is React.js, Next.js, Node.js, TypeScript, JavaScript, MongoDB, and SQL, with strong experience across both frontend and backend development.

I don’t just focus on writing code—I focus on understanding the problem, designing the right solution, and delivering software that is scalable, maintainable, and built for the long term.

🚀 What I Can Bring to Your Project

Frontend Development

I have extensive experience building modern, responsive, and performance-focused applications using:

• React.js
• Next.js (App Router)
• TypeScript / JavaScript
• SSR, SSG & ISR
• Tailwind CSS
• Ant Design / MUI / Styled Components
• Redux Toolkit
• React Hook Form / Formik / Yup
• REST API & third-party API integrations
• Reusable component architecture
• SEO & performance optimization

I’m particularly experienced with Next.js applications where SSR, SSG, ISR, SEO, caching, Core Web Vitals, and scalability matter.

Backend Development

I can also handle the complete backend side of an application using:

• Node.js
• Nest.js
• REST API development
• Authentication & authorization
• Business logic
• MongoDB
• MySQL / SQL Server
• API integrations
• Error handling & validation
• Database design and optimization

This allows me to take ownership of features end-to-end—from database and API design to the final frontend implementation.

☁️ Enterprise & Production Experience

I’ve worked with enterprise-level applications and understand the difference between building a quick prototype and building something that needs to work reliably in production.

My experience includes:

• Docker
• Azure
• Azure App Service
• Azure Container Registry
• Azure DevOps
• CI/CD pipelines
• Git-based development workflows
• Automated testing
• Code quality & Sonar
• React Testing Library & Jest

I’m comfortable working within an existing engineering ecosystem and following established standards rather than forcing an entirely new approach.

🧠 I Think Beyond the Ticket

One of my biggest strengths is that I don’t treat development as simply:

“Give me a task → I write code → task completed.”

Before implementing something, I try to understand:

What problem are we solving?
Why are we solving it this way?
How will this behave at scale?
What happens when something fails?
Will this still be maintainable 6–12 months from now?
Can we make it faster, simpler, or more reliable?

That mindset has helped me work effectively on complex applications and make better technical decisions.

👨‍💻 Team Leadership & Code Quality

Along with hands-on development, I have experience leading developers, reviewing code, mentoring junior team members, breaking requirements into technical tasks, and maintaining development standards.

I pay close attention to:

• Clean & reusable code
• Component architecture
• Performance
• Security
• Error handling
• Testing
• Maintainability
• Scalability
• Code reviews
• Proper Git practices

I’m comfortable working independently, but I’m equally comfortable collaborating with designers, backend developers, QA engineers, product owners, and other stakeholders.

🎯 What You Can Expect From Me

If we work together, my goal is not simply to deliver the requested feature.

You can expect me to:

✅ Take ownership of the work
✅ Communicate clearly and proactively
✅ Ask the right questions before implementation
✅ Identify potential problems early
✅ Suggest better approaches when I see them
✅ Write maintainable, production-quality code
✅ Consider performance and scalability from the beginning
✅ Respect existing architecture and coding standards
✅ Deliver features end-to-end when required

🔥 Why I Could Be a Good Fit

If you’re looking for someone who can understand requirements, make technical decisions, work across frontend and backend, and take ownership of the complete feature, I believe my experience can add real value to your project.

I’m especially interested in projects where I can contribute beyond just implementation—architecture, performance, problem solving, technical decisions, and long-term maintainability.

If you share your project requirements, current tech stack, existing architecture/codebase, and the main challenge you’re trying to solve, I’d be happy to take a look and discuss how I would approach it.

I’d love to hear what you’re building. 🚀
