Every product begins with understanding how people work. I turn complex business processes into scalable software, combining thoughtful architecture, reliable engineering, and practical solutions that move from concept to production.

Rusbyte Studio
Founder of Rusbyte — my independent studio, delivering client software from relational schema through to production.
My Journey
How I build, and where I've been.
Most of my work starts the same way: a business is running something critical on spreadsheets, paper, or half a dozen disconnected tools, and it has stopped scaling. I map how the operation actually works, model it properly in the database, and build the platform on top — the dispatch board, the offer ledger, the driver app. Logistics and real estate are where I've spent the most time.
The structural decisions are the ones I care about. A schema that reflects real business rules, permissions enforced on the server rather than hidden in the UI, and boundaries clear enough that the next developer can extend the system without breaking it. Software that works on launch day is the low bar; the harder goal is software still worth maintaining a year later.
I learn fastest by shipping and by explaining. As Web Development Assistant Lead for Google Developer Groups on Campus, I built and maintained the chapter site across the academic year while mentoring students through React and Node.js — teaching a concept is the quickest way to find out how well you actually understand it.
Timeline
Experience & Milestones
Chief Technology Officer (CTO)
LeadershipAWS Student Builder Group – National University Baliwag
2026 – Present
Set the technical direction for the chapter and build the programs that get members from tutorial-following to shipping real projects.
- Own the chapter's technical direction, from which technologies members learn to how projects are structured and reviewed.
- Mentor members through software engineering and cloud fundamentals, with an emphasis on why architectural decisions are made rather than which commands to run.
- Design and run workshops, collaborative builds, and live coding sessions that give members production-shaped experience before graduation.
- Drive adoption of AWS and industry practices across the group, giving members skills that carry directly into technical interviews.
Founder & Full-Stack Developer
WorkRusbyte — Independent Software Development Studio
Present
Founded and run an independent studio delivering custom business platforms end to end — scoping the problem with the client, modelling it in the database, building the product, and owning it in production. Clients across the Philippines, Australia, and the UAE.
- Own client engagements end to end: translating how a business actually operates into a schema and a product, then staying responsible for it after launch.
- Design normalized relational schemas and the REST APIs on top of them, with authentication and role-based access control enforced server-side.
- Build reporting dashboards that give operators a live view of their business instead of a weekly spreadsheet export.
- Run deployment pipelines, server configuration, and hosting so clients ship updates without downtime or a dedicated ops hire.
Full-Stack Developer
WorkOakford Realty
Real estate company operating in Australia · Feb 2026 – Mar 2026
Built core platform features for an Australian agency managing listings, client history, and daily operations — focused on the data layer and the permission model protecting client records.
- Designed the relational schema behind property records and agent assignments, giving the platform a consistent source of truth for listing ownership.
- Built the backend API routes and the listings administration dashboard agents use day to day.
- Implemented authentication and role-based permissions so client contract documents are only reachable by the agents entitled to them.
- Consolidated property records and active transaction logs into single dashboard views, removing the need to cross-reference separate systems.
- Profiled and optimized slow queries and refactored core components, measurably improving dashboard load times.
Web Development Assistant Lead
LeadershipGoogle Developer Groups on Campus
AY 2024 – 2025
Owned the chapter's web presence for the full academic year and mentored students through their first real builds.
- Built and maintained the chapter website end to end, owning both the front-end implementation and content through the academic year.
- Mentored students on React, Node.js, and Firebase in lab hours and live code reviews, working through their debugging rather than handing over answers.
- Helped coordinate campus tech events and developer bootcamps, turning attendance into students who had actually shipped something.
Self-Directed Software Journey & Open Source
WorkIndependent Builder
2020 – 2026
Taught myself the fundamentals the way they stick — by building. Computer science foundations, relational modelling, and backend architecture, worked out through projects that had to actually run.
- Built working fluency in JavaScript/TypeScript, Python, and C++ through projects rather than coursework alone.
- Wrote and deployed automation tools for workflow management and data processing, several released as open source.
- Worked through relational database design in PostgreSQL and MySQL sandboxes — normalization, indexing, and query planning — which became the foundation for the client systems that followed.

Independent Studio
Founder & Full-Stack Developer
Custom business platforms, mobile tools, and database architecture.
I started Rusbyte to work with businesses directly, without the layers that usually sit between a company and the person building its software. One point of accountability from the first scoping conversation through to production. The studio builds web platforms, mobile tools, and the relational backends underneath them — shaped around how each client actually operates rather than a template they have to adapt to.
