Professional work first. Side projects on the side.

RYNXPLAY, SUGOLA, ADe Garage, TruPeople HR, and Reynalyn Grace are business-facing work. The rest are personal apps I built for fun and learning.

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.

  • Food, grocery, pharmacy, courier & custom errands
  • Riders accept orders directly — no chat operator
  • Serving Sto. Tomas since 2021

Business outcome: A barangay-scale alternative to national delivery apps — instant booking, local riders who know the area, and live tracking for 3K+ customers since 2021.

ADe Garage

Thai concept motorcycle parts — browse online, order where you shop.

ADe Garage is a multi-channel brand hub for a motorcycle parts shop in Tagum City — Yasaki, RCB, SuperKips, and genuine OEM parts for Raider, Ninja, and underbone builds. Riders browse the catalog on the site, then order on Shopee, TikTok Shop, or Messenger without paying for a monthly storefront.

  • Catalog hub linking Shopee, TikTok Shop & Messenger
  • Shopify-ready architecture for future web checkout
  • Logo-aligned cyan theme with animated product cards

Business outcome: The shop gets a professional web presence that drives orders to the channels it already uses — nationwide shipping messaging, fitment help on Messenger, and room to add Lazada when it launches.

TruPeople HR

From clock-in to payslip — HR for Philippine small businesses.

TruPeople HR is a multi-tenant SaaS for sari-sari stores, cafés, and growing teams across the Philippines. Staff clock in from any phone, DTR tallies automatically, payslips go out by email, and a group-wide people registry lets owners check rehire history before hiring again.

  • Clock-in, DTR, and emailed payslips from any phone
  • Multi-company ops with org chart & people registry
  • Rehire check across affiliated businesses

Business outcome: Owners replace spreadsheet payroll and paper DTR with one login across multiple companies — clock-in, leave, org chart, and rehire screening without enterprise HR bloat.

Personal projects

Side apps I built on my own time.

These are personal experiments — not client or commercial work. They show the range of what I can ship; my professional work is client and business builds.
