🤝 I work like a product partner, I own the technical decisions so you don't have to babysit them.
As a Full Stack Developer, I'm the person teams bring in when they need someone who can handle both ends of the stack without losing sight of the product. I've built fintech platforms handling 50,000+ daily requests, shipped an MVP from scratch to 1,000 users in 3 months, reduced API response times by 30%, and led engineering teams delivering production features across microservices.
