Hi, my name is Samil Abud
I'm a Full-Stack Web Developer!
About me
I'm a Senior Full-Stack & AI Engineer with 10+ years building production web applications — from auth and dashboards to real-time messaging, payments, and, more recently, AI-powered systems. I like owning things end-to-end, whether that's an LLM integration or the platform around it.
Right now, I'm building the multi-tenant platform behind Evercred, a healthcare credentialing SaaS — physician, enterprise, and admin portals, plus an AI-powered document-processing pipeline: Python/Django handles preprocessing, then Claude's vision capability extracts structured data directly from document images. I also fixed a real accuracy bug — extraction was only ~70% correct on certain formats, so I added a validation step that cross-checks the result against the PDF's embedded text layer, raising accuracy to ~100%. I'm also actively freelancing on Upwork, and I still enjoy building software from scratch, hunting down bugs, and collaborating to ship great products.
