Tired of dealing with messy data, unreliable automation, or systems that don’t scale? I help companies build production-ready systems that automate complex workflows, process messy data (PDFs, APIs, databases), and stay reliable as they grow. Hi, I’m Fauzan 👋 Software Engineer + AI/ML Engineer with 8+ years of experience, mostly in energy and industrial systems (AU & ID markets). I’ve solved problems like: - Automated energy procurement workflows (reduced months/weeks → days/hours) - Built IDP pipelines to extract data from highly variable energy bills (PDF/Excel) - Designed end-to-end billing systems (ingestion → validation → invoicing → Xero) - Delivered energy analytics dashboards for cost optimization and operational insights - Enabled emissions reporting using structured energy data and emission factors - Deployed production ML systems (semantic search, document AI) What I can help you with: - Automation & Data Pipelines → extract, validate, and process data from PDFs, APIs, and databases into reliable workflows - Document AI (IDP) → OCR + Vision LLM pipelines to turn complex documents (invoices, bills) into structured data - Energy Data & Reporting → consumption analysis, cost tracking, dashboards, and emissions reporting (with correct factors) - AI / ML Systems → semantic search, forecasting, and production-ready ML pipelines (MLflow, deployment, monitoring) - Backend Systems → scalable Python services (FastAPI, Django), async processing (Celery, Redis) - Frontend & Admin Interfaces → React, Next.js, and mobile apps (Flutter) for actionable insights - Infrastructure & Scaling → CI/CD, Docker, AWS/Azure, monitoring with Grafana & Prometheus Tech I use (when it actually matters) - Backend: Python, FastAPI, Django, Flask - Frontend/Mobile: NextJS/React, Flutter (Mobile) - Data & ML: Pandas, NumPy, MLflow, NLP pipelines, Scikit-Learn - AI Stack: LLMs (GPT-4o/Vision), vector search (Milvus) - Infra: Docker, AWS, Azure, Celery, Redis - Database: PostgreSQL, MongoDB How I work I focus on delivering working systems, not just code: - Break down messy problems into structured systems - I move fast using spec-driven + AI-assisted development - I design systems that are simple, reliable, and maintainable - I avoid over-engineering — every component must justify its cost I take on projects I’m 100% confident I can deliver. If you need someone who can take a complex, messy problem and turn it into a clean, scalable system — let’s talk. If you’d like to discuss your project, just send me a message. We’ll review your requirements together and make sure the solution is tailored exactly to what you need. 🚀📊
