I’m a software developer in training with a strong focus on backend systems, scalable architectures, and real-world product development.

My background in HR, recruitment, and business analysis gives me a strong edge: I understand users, requirements, and trade-offs — and I build software that solves actual problems, not just technical ones.

Right now, I’m building production-ready applications using Java, Next.js 16, Supabase, React Native, and advanced SQL, with a growing emphasis on backend architecture and system design.

• Backend architecture & data modeling
• Clean API design and authorization patterns
• Scalable, maintainable full-stack systems
• Bridging business requirements with technical solutions
