What I'm looking for

I'm looking to build scalable, high-quality business applications with cross-functional teams, applying clean architecture, strong engineering practices, and continuous learning to solve complex product challenges.

I've built scalable enterprise applications at TechnoNext Software, including a Japanese inventory management system and an Online Travel Agency platform with flight, insurance, payment, and supplier integrations. I improved legacy API response times by approximately 40% through SOLID principles and Clean Architecture.

I lead engineers through standups, code reviews, and sprint planning while designing systems, databases, and business solutions for high-volume transactions. My work includes .NET 8, PostgreSQL, SQL Server, Kafka, Redis, JWT authentication, Angular, and high-throughput bulk inserts.

Previously, I delivered HR/Payroll, inventory, VAT, and ERP solutions at iBOS, Pakiza Technovation, and Genuine Technology & Research. I enjoy clean code, best practices, continuous learning, and building secure APIs that solve real business needs.
