What I'm looking for

I’m looking to build scalable, reliable backend systems where I can solve complex business logic, improve performance, design robust APIs, and deepen my work in system design and distributed systems.

I build scalable, reliable, high-performance backend systems and choose technologies based on the problem rather than a single stack.

At PT Swamedia Informatika, I work on backend development using Laravel, Node.js, Express.js, Spring Boot, PHP, Python, PostgreSQL, MySQL, and Oracle Database.

I’ve also delivered backend work for S8LLS using Go, Python, TypeScript, and PostgreSQL, and built course applications at Intelligo ID. As Intelligo ID’s CTO, I managed developer members and contributed to technology management and IT strategy.

I focus on backend architecture, robust APIs, complex business logic, batch and parallel processing, query optimization, and service integration. I’m deepening my work in system design, distributed systems, and performance optimization while prioritizing clean, maintainable code.
