Über mich
Do you want a reliable and able developer who loves his work and can communicate clearly? Do you want someone who can make a great contribution to the betterment and prosperity of the company? My goal is to be your person. I am a professional web (React.js/React Native/Node.js) and mobile developer with 7+ years of experience. I prefer to code from scratch and create fully custom websites. My designs follow a minimalist approach and focus on simplistic powerful aesthetics. I have completed a wide range of projects for 7+ years. As a Software Developer, I constantly provide solutions for users’ problems. I can be working on the occasional quick fix as well as more complex strategic solutions. I consider myself creative, self-confident, and hardworking. I would greatly appreciate the opportunity to meet with you and further discuss my qualifications and your requirements in detail. Thank you for your consideration, and I look forward to speaking with you soon. Best Regards.
