Summary
👤
SeniorArief Syaifuddin is a pragmatic back-end developer with 9 years of experience building revenue-driving services and integrations across finance, telco, and consumer event platforms. Self-taught since age 10, he brings a low-level curiosity born from reverse-engineering games to modern stack choices like Java/Quarkus and PostgreSQL, while also fluently using Node.js/TypeScript and Go. He focuses on maintainability and observability—applying tools like Jacoco, Valkey caching, and pragmatic indexing (pg_trgm) to solve performance and concurrency issues. His recent work centralizes intercompany transactions and designs dynamic master-data ERDs, with a strong knack for bridging technical and communication challenges when integrating disparate teams. Comfortable operating in production-critical environments (on-prem/cloud replication, events with intermittent connectivity), he consistently delivers reliable services that support business operations. Based in Kudus, Indonesia, he pairs engineering discipline with quick learning and a willingness to tackle messy legacy systems.
