About

Hi there! 👋 I'm Sarthak. I'm a software engineer with over three years of experience in JavaScript, TypeScript, React and Preact, currently working @ Cyberhaven! My work focuses on creating effective, user-centered web applications. My experience includes in-depth knowledge of web development, and I also have a solid grounding in unit testing with frameworks like Jest and React Testing Library. Beyond work, I enjoy studying computing concepts like Theory of Computation, Finite State Automata, Computer Graphics, Shaders, Operating Systems, Compiler Design, and Programming Languages. I love to work with C++ to build on this interest, and also enjoy writing shaders and making all sorts of cool stuff from those. I've completed my Bachelor's and Masters in Computer Science & Engineering from National Institute of Technology Hamirpur. I'm always curious and excited to learn about new tools & technology especially web and video games related stuff, so feel free to hit me up anytime for collaborations or for a quick talk. I love playing video games 🎮, listening to music 🎶, playing 🎸and watching movies 🎥. Hope you've a lovely day ahead.🌞 My Portfolio - https://www.itslaz.com/ GitHub - https://github.com/TheLazarus Email - sarthak.laz@gmail.com Skills: React, Preact, Javascript, Typescript, Webpack, Node, Jest, React Testing Library, C++, C#, .NET, Jira, Git, Linux
