About
Hi, I'm Bayu Wijaya, a dedicated and results-driven Software Engineer with 8+ years of experience specializing in robust mobile application development. My career journey, which began with a strong foundation in Informatics Engineering (Universitas Komputer Indonesia) and active development work at the Codelabs Division, has always been marked by continuous learning and a commitment to excellence.
I thrive on building user-centric applications and solving complex technical challenges. Most recently, I successfully transitioned my expertise from Android to become an iOS Developer at Maybank, and I have since expanded into AI Engineering, building automation pipelines and LLM-powered workflows using tools like n8n, OpenAI, and LangChain — including integrating Faster-Whisper for real-time speech-to-text on video conferences and using Ollama to generate automated meeting summaries. I am now focused on combining modern mobile architecture with practical AI integrations to deliver high-performance, secure, and intelligent digital products.
