Santo Domingo, DRAbout me
I build full stack products at the intersection of engineering, product, and growth.
I’m a Full Stack Software Engineer building SaaS products, developer tools, and growth-oriented web systems.
My work sits at the intersection of engineering, product, and marketing: landing pages, internal tools, dashboards, content workflows, analytics-ready experiences, and the backend logic that makes them useful.
Lately, I’ve been building Qiknest, a modular business workspace for small teams where I explore product-led growth, CRM workflows, KPI dashboards, website building, store flows, and practical systems that help small businesses understand and grow their operations.
Growth Engineering
Building landing pages, conversion flows, product experiments, and useful web experiences that help people discover and try software.
Marketing Systems

Full Stack Product Work
Shipping frontend experiences, APIs, dashboards, data models, and backend logic across complete product flows.
Small Business SaaS
