Muhammad Faizin

I build Golang and Python backend systems for document extraction, AI integration, and SaaS products for small and medium businesses. At PT Sxored Veritas, I build REST APIs for extracting transaction data from bank statements and Python microservices for text-based and scanned PDF extraction.

I created pdf-extractor, a lightweight Python library, CLI, and FastAPI REST API that extracts text from native and scanned PDFs, document photos, and images on small CPU-only VPS instances. I designed its hybrid PyMuPDF and PaddleOCR approach to keep resource usage efficient under limited RAM.

I also build independent SaaS products from architecture planning through go-to-market, including an AI-based invoicing system with WhatsApp Cloud API, Claude API, PDF generation, and Flip for Business payments. I built and marketed Toko Senang, a POS and inventory SaaS for Indonesian small businesses.

Previously, I maintained React Native mobile applications and Node.js backends at PT Jaya Nusantara Teknova, including education-sector and Indonesian diaspora applications. I’m available to contribute full-time remotely.
