John Micheal Acera - Backend-Focused Software Engineer

Background

How I Got Here

Foundation

Information Technology Degree

Graduated with a degree in IT. Like most people, survival came first — the degree was a starting point, not a shortcut.

Inside the system

Government Accounting

Interned in a government accounting department, then stayed as a casual employee for nearly a year. Saw firsthand how public offices actually operate — the approvals, the paperwork, the operational realities behind every process. That context lives in everything I now build for institutions.

At the human layer

Customer Service

Spent years in customer-facing work — constant, direct interaction with people solving real problems. Learned that clear systems and clear communication are not optional; they're what separates a process that works from one that doesn't.

Now

Software Engineering

Currently a software engineer at Sportality, a sports technology company in Sweden — six years building there. Alongside that, independent work back home: cooperative infrastructure and government platforms for local institutions in the Philippines. The earlier work wasn't a detour. It's why the software I write is designed for people, not just for developers.

Case Study
QR Attendance Tracker
Deployed

QR Attendance Tracker

A React Native attendance app for Bucas Grande Foundation College and the Division Schools Press Conference. Gate staff scan student QR codes to mark presence in real time, with offline capture and auto-sync when the connection returns — so attendance still works in low-signal school venues.

Case Study
MD Events and Services
Deployed

MD Events and Services

A tenant website built as part of the LocalWebVentures multi-tenant platform. It features real-time content management, booking system, and dashboard control for event services. Designed to help small businesses easily manage and present their offerings online.
