👨‍💻 About Me

const john: SoftwareEngineer = {
  name:       "John Okyere",
  location:   "Ghana, West Africa 🇬🇭",
  role:       "Software Engineer",
  focus:      ["Blockchain", "Cloud Engineering", "Backend Systems", "Cybersecurity"],
  exploring:  ["Zero-Knowledge Proofs", "AI + Blockchain", "Microservice Architecture"],
  portfolio:  "https://johnokyere.xyz",
  available:  true, // Open to opportunities!
  funFact:    "There are 10 types of people — those who understand binary and those who don't.",
};

I'm a passionate software engineer building solutions that merge technology, innovation, and impact. From smart contracts on Ethereum to serverless APIs on AWS, I bridge the gap between cutting-edge research and real-world execution. I'm also a strong advocate for tech education and digital empowerment across Africa.
