I’m a backend software engineer with 4+ years of experience building and scaling high-traffic distributed systems, including search and recommendation platforms handling tens of millions of requests per day. I’ve worked across companies like Tokopedia and Carousell, focusing on performance optimization, system reliability, and microservices architecture. My technical strengths are in Go, distributed systems, and backend performance. I’ve spent a lot of time optimizing latency, designing caching strategies, and improving large-scale search systems using tools like Redis and Elasticsearch. I’m comfortable working on APIs, data pipelines, and systems that require high availability and scalability. When working with clients, I prefer clear and direct communication. I usually align early on requirements, break down tasks into manageable steps, and provide regular updates on progress. I’m comfortable using tools like Slack, Jira, Notion, and GitHub, and I try to keep communication async-friendly while still being responsive when needed. I’m based in Indonesia (UTC+7) and can overlap with most US time zones for a few hours each day. I use AI tools like Claude Code, ChatGPT and GitHub Copilot in my daily workflow to speed up development, explore solutions, and reduce context switching. I find them especially useful for drafting code, debugging, and summarizing technical concepts. At the same time, I’m careful about validating outputs, especially for production systems, to ensure correctness and reliability. Overall, I focus on building backend systems that are fast, reliable, and scalable, while keeping communication clear and collaborative.
