About Me:

Software Developer with a Master’s degree and 3 years of front-end experience. I am passionate about client-side software development, having built over 20 projects in React, TS, JS, HTML, CSS.
My experience spans multiple projects, including custom web apps, e-commerce platforms, and even mini-games, where I’ve integrated APIs, optimized front-end designs and adapted it for various web and mobile versions.
Each project has deepened my understanding of how great design and cutting-edge technology can intersect to create something truly memorable.
Beyond that, my software development work is based on clean, modular code that is both efficient and maintainable. My current research includes extending into React, which is a natural progression as I continue to search for better tools for building scalable, robust web applications.

Languages and tools

Code examples:

Is a number prime? Define a function that takes an integer argument and returns a logical value true or false depending on if the integer is a prime.

const isPrime = num => {
    for(let i = 2, s = Math.sqrt(num); i <= s; i++) {
        if(num % i === 0) return false;
    }
    return num > 1;
}

console.log(isPrime(1)) //false
console.log(isPrime(2)) //true
console.log(isPrime(-1)) //false

RGB To Hex Conversion The rgb function is incomplete. Complete it so that passing in RGB decimal values will result in a hexadecimal representation being returned. Valid decimal values for RGB are 0 - 255. Any values that fall out of that range must be rounded to the closest valid value.

function rgb(r, g, b) {
  let str = '';
  if (r < 0) r = 0;
  if (g < 0) g = 0;
  if (b < 0) b = 0;
  if (r > 255) r = 255;
  if (g > 255) g = 255;
  if (b > 255) b = 255;
  str = `${('0' + r.toString(16)).slice(-2)}${('0' + g.toString(16)).slice(-2)}${('0' + b.toString(16)).slice(-2)}`
  return str.toUpperCase();
}

console.log(rgb(255, 255, 255)) //"FFFFFF"
console.log(rgb(255, 255, 300)) //"FFFFFF"
console.log(rgb(0, 0, 0)) //"000000"
console.log(rgb(148, 0, 211)) //"9400D3"
