About Me

WHO I AM

What I Do

I build backend APIs with Java and Node.js, deploy them on AWS, and create full-stack SaaS applications with the MERN stack. GoMove, my fitness coaching platform, runs in production with paying clients on a monthly subscription.

Education

Technical degree in Software Development. Self-taught in cloud infrastructure, DevOps, and modern web development. Constantly learning and shipping — I believe the best education is building real products that people use and pay for.
