About

As a passionate Software Engineer with 3 years of industry experience, I thrive at the intersection of scalable backend systems and impactful product development. Over the past few years, I’ve contributed to high-growth tech companies like OLX Indonesia, Oliv India, and Fi, driving initiatives that improved system performance, product features, and operational efficiency. My experience spans building and optimizing backend services using Java, Spring Boot, Golang, gRPC, Kafka, Redis, and PostgreSQL, among others. I have worked extensively on distributed systems, microservices architecture, and API development, delivering solutions that have directly impacted revenue and system stability. Beyond coding, I enjoy working on complex system migrations, designing resilient infrastructure, improving test coverage, and leading root cause analysis for critical issues. I'm passionate about writing clean, maintainable code and collaborating cross-functionally to create seamless user experiences. Always eager to learn, adapt, and tackle new challenges, I'm excited about building products that scale and solve real-world problems.
