I build full-stack web platforms, POS/CRM systems, and AI-driven product features.
PeruWhat I'm looking for
I've built and deployed production web platforms for clients, including Boom POS, a full point-of-sale and CRM system covering inventory, sales, and client management. I also delivered websites, admin dashboards, product catalogs, and backend-integrated platforms for local businesses.
For GEOTOP, I developed a cloud-based certificate management system with QR verification, digitizing certificate issuance and validation using Flask, Amazon S3, and Google Cloud. My work spans requirements gathering, technical proposals, architecture design, deployment, and post-launch support.
I use React, Next.js, Python, PostgreSQL, and MongoDB to turn business needs into scalable technical solutions. I've also applied edge inference, semantic search, and RAG pipelines to independent product prototypes.
