About Stefan Kostenko

Me llamo Stefan, soy apasionado de la tecnología desde muy pequeño. Siempre me han gustado los juegos y por eso me llamó tanto la atención estudiar el mundo de la informática. 💻🎮Luego vi que podía crear sitios web y hacerlos a mi gusto y es por eso que me decanté por el mundo del desarrollo. 💕A día de hoy, he finalizado mis estudios como desarrollador web y trabajo como junior ‘full-stack developer’. Pero, aparte del desarrollo web, me entusiasma mucho el mundo de la ciberseguridad 🔒 y siempre intento aprender cosas nuevas. 💡
