I build production software: APIs, web apps, SaaS products, automations, and AI features. Hands-on across the stack — from the first commit to something that holds up in production.
Computer Engineer with 10+ years writing software that runs in production. I work as a senior software engineer: backend, frontend, cloud, integrations, and applied AI. I have led teams when the product needed it, but the work I enjoy — and what I take on freelance — is building. I currently ship products at Mentores Tech (including Zeli Medic), where I also do consulting and freelance development. Every project on this site is software I designed and developed.
Products I designed and developed. Open a project for screenshots, demos, and how it was built.
Building SaaS products, internal tools, automations, and AI-assisted platforms for education, healthcare, and companies. Shipped new features for a medical-center SaaS (scheduling, financial operations, patient care) and an internal hands-on training platform; improved the SDLC with agents and AI tools.
