Profile
I am a Full-Stack Developer with over 2 years of commercial experience, specializing in building modern,
responsive, and interactive web applications with React, TypeScript, and Node.js. I have commercial
experience developing and maintaining web applications, working across both front-end and back-end,
from building reusable UI components to implementing APIs and database functionality. My main expertise
includes React, Next.js, TypeScript, Node.js, Express.js, NestJS, PostgreSQL, MongoDB, and Prisma
ORM. I also have experience building interactive 3D web experiences using Three.js, React Three Fiber,
and GSAP, as well as deploying and maintaining applications using Docker, Nginx, and PM2.
I am comfortable working on existing codebases, developing new features, debugging production issues,
refactoring code, and improving application performance and scalability. I also have previous experience
with C#, .NET Core, Microsoft SQL Server, and Entity Framework Core.
