About Didik M.

I’m a Senior Full-Stack Software Engineer with 8+ years of experience building scalable web applications, AI-enabled workflows, fintech platforms, logistics systems, and SaaS products for companies in the United States, Australia, and Indonesia. My recent work focuses on AI-native business automation, including LLM-powered document extraction, financial transaction categorization, contact prediction, accounting workflow integration, human-in-the-loop review systems, token usage tracking, and production observability. I have hands-on experience across the full product lifecycle: designing architecture, building backend APIs, developing frontend applications, integrating third-party services, improving system reliability, debugging production issues, and collaborating directly with founders and product teams. Technically, I work mainly with React, Next.js, Node.js, NestJS, Golang, PostgreSQL, MongoDB, Redis, and Google Cloud Platform. I also work with AI tools and platforms such as Gemini, Vertex AI, Google Document AI, OpenAI API, n8n, and OpenClaw. Some areas I’ve worked on include- AI finance automation and accounting workflows - OCR and financial document extraction - Xero/accounting integration - AI project management automation - Fintech and wealth management products - Logistics tracking platforms - Cloud infrastructure and production debugging - Grafana/Prometheus observability I’m especially interested in building reliable AI-native software systems that solve real business problems, not just simple chatbot wrappers. I enjoy working on products where backend architecture, AI workflows, integrations, and production reliability all matter. I’m open to international opportunities, especially in AI, fintech, SaaS, backend engineering, automation, and Saudi/GCC remote or relocation roles.
