About
I'm an Information Technology graduate from Cebu Institute of Technology University, now a software developer consultant at Oltek Solutions Corp. I build real production systems, not demo apps — frontend, backend, cloud infrastructure, deployment pipelines, and the performance work in between.
I've shipped deployed systems used by real people — including my own SaaS platform, EstabWeb, which lets small businesses launch a managed website in a day or two. The approach is the same every time: build fast, build reliably, and deploy so it doesn't break in the real world.

Testimonials
What partners and stakeholders say about working together.
As team lead, I relied on Danrave to ship StudyBoost features fast and keep releases on track. He owned the stack, unblocked teammates, and delivered production-ready code without handholding.
Danrave turned my portfolio vision into a polished site that loads fast and works flawlessly for my clients. He iterated quickly on feedback and treated the launch like it was his own brand.
For our Mass Communication Wildcats Radio project, he handled streaming, backend, and UI under tight deadlines. When blockers appeared, he solved them without drama and kept the team moving.
