I’m a Software Engineer with 7+ years of experience building and optimizing scalable, user-focused web applications. With a strong foundation in frontend engineering (React, Next.js, Angular, Tailwind CSS) and backend systems (Node.js, NestJS, PostgreSQL, MongoDB, Java/Spring Boot), I deliver end-to-end solutions that balance performance, usability, and scalability.

I’ve worked with both startups and enterprise companies, building apps that serve thousands to millions of users. From sleek frontend interfaces to robust backend infrastructures, I bring a holistic approach to development. My expertise includes:

- Frontend
- React, Next.js, Angular, Redux, Tailwind CSS
- Building dynamic, responsive, and accessible UIs
- Optimizing load times and performance

- Backend
- Node.js, NestJS, Express, PostgreSQL, MongoDB
- RESTful API design, authentication (JWT, OAuth2), and integrations
- Java & Spring Boot for enterprise-grade systems

- Fullstack Delivery
- Designing and deploying complete web applications from scratch
- Debugging and optimizing existing systems (frontend + backend)
- Deployments with Vercel, Netlify, Heroku, and CI/CD pipelines

What I’ve achieved for past clients/companies:
- Improved application load speed by 20%, enhancing user retention across 50K+ sessions.
- Boosted mobile engagement by 37% with responsive UI engineering.
- Modernized legacy architectures, increasing system scalability by 75%.
- Reduced system bugs by 86% through proactive debugging and testing.
- Delivered high-performance enterprise apps serving millions of identity verification requests.

Whether you need a frontend-heavy developer to craft an intuitive UI, a backend engineer to design robust APIs, or a fullstack partner to take your idea from concept to deployment, I can help.

If you’re looking for someone who can own the full development cycle, let’s connect. I’d love to help bring your vision to life.
