Ryan Vince Castillo · Remote developer for business owners

Build software that saves your business time and money.

Ryan Vince Castillo (Ryan Castillo) — a full-stack and AI developer who helps business owners replace manual work, cut tool costs, and ship custom systems without agency overhead.

How I help

Software that pays for itself — in time saved and costs cut.

I work with business owners who are tired of duct-taping tools together or paying for software that almost fits. I build lean systems that remove friction from daily operations.

How engagements work

Simple process. No surprises.

  1. Step 01

    Understand the bottleneck

    We map what's costing you time or money today — manual steps, tool sprawl, or workarounds your team built out of necessity.

  2. Step 02

    Scope something shippable

    I propose a focused first version with a clear price and timeline. No open-ended discovery that burns budget before anything ships.

  3. Step 03

    Build, launch, iterate

    You get working software in your hands early. We refine based on real use — not slide decks.

RYNXPLAY

Run your PisoNet shop from one dashboard.

RYNXPLAY is a multi-tenant SaaS platform for coin-operated device rental shops in the Philippines. Shop owners manage PCs, phones, and tablets from one command center — coin drops credit sessions automatically, devices lock and unlock in real time, and every peso is tracked across branches.

  • Live device control across Windows, Android & web
  • Coin acceptors credit sessions automatically
  • Multi-branch ops with staff roles & reports

Business outcome: Shop owners replace manual timers and paper logs with automated coin-to-session tracking, live floor visibility, and branch-level sales reports — reducing revenue leakage and scaling without hiring more floor staff.

  • Shopify-ready architecture for future web checkout

About

A developer who speaks business, not just code.

I'm Ryan Vince Castillo, based in Davao City, Philippines and working remotely with business owners worldwide. Most of my clients aren't technical — they care about outcomes: less admin, fewer mistakes, lower software bills, and systems that actually match how their team works.

I handle everything from customer-facing websites to internal tools, automations, and AI-assisted workflows — including RYNXPLAY, a SaaS platform built for PisoNet and device rental shops. You get one person who can design, build, deploy, and maintain — which typically costs far less than hiring an agency or juggling multiple freelancers.

  • Built to reduce cost

    I focus on what removes manual work or replaces expensive tools — not features that look good in a demo but never get used.

  • Shipped on honest timelines

    Clear scope, regular updates, working software early. You always know where things stand and what you're paying for.

  • One person, end to end

    You work directly with the developer — no account managers, no handoffs. Faster decisions, fewer misunderstandings.
