Philippine Fire and Marine Insurance Corp

About
I'm Mark Orosa. I build software that removes work.
I've been writing software professionally since 2010 — 15+ years across telecom, insurance, digital ventures, and managed cloud. Exiaph is the consultancy I built to put that work under one roof.

Why Exiaph exists
Most businesses I've worked with — at every size — have at least one manual workflow that shouldn't be manual. Someone copy-pasting between two systems. A "weekly report" that takes four hours. An approval chain that lives in email and routinely loses requests.
The frustrating part: the fix is almost always custom software. Not a bigger SaaS subscription, not "we should look into Zapier" — a real, scoped automation built once and run forever. But that requires a dev partner who understands business workflows, not just code.
Exiaph is that partner.
Stack
Day to day I work in Next.js, TypeScript, PHP (Yii2, Laravel), Python, Postgres, Supabase, and Vercel. Comfortable across AWS, Azure, Digital Ocean, and self-hosted Proxmox. I pick based on what the client already runs, not what's trendy.
How to work with me
- →Best fit: SMBs (PH or international) with a clear manual workflow that's eating measurable team time.
- →Engagement starts with a free 30-min discovery call, then a paid workflow audit that produces a real scoped proposal.
- →I don't take equity-only or "let's see how it goes" engagements.
- →Selective intake: Exiaph maintains three concurrent engagements. We add roughly one new client per quarter when bandwidth allows. Earliest standard intake: Q3 2026.
- →Based in San Pablo, Laguna — nine of the last fifteen years remote-to-Sydney, so timezone-spanning collaboration is the default mode, not an exception.
