About Me

Passionate Developer & Problem Solver

I'm Tanjila Akter, a passionate and results-driven Senior Software Engineer with over 5 years of experience in building scalable, modern web applications. I specialize in React.js, Next.js, Node.js, TypeScript, and have a strong command over full-stack development using the MERN stack.

I've worked across diverse industries, delivering high-performance applications and collaborating closely with cross-functional teams. With a strong foundation in problem-solving (500+ problems solved), UI/UX design, and a keen eye for detail, I focus on building elegant, responsive, and efficient web solutions.

I'm currently working at Cosmos Tech Labs where I focus on system design, real-time features, and advanced Next.js-based architectures. I'm also actively learning Python, Django, and AWS.
