};What You Actually Get
Not just a developer — a registered engineer who has shipped real systems used by real businesses. Here's the difference that matters when you're putting your money on the line.
End-to-End System Delivery
You don't need to hire a separate frontend dev, backend dev, and DBA. I design, build, and deploy the entire stack — from database schema to user interface — so your system ships coherent, not stitched together.
Delivered: POS, Payroll, HRIS, LMS, Clinic SystemsSME-Priced, Enterprise-Quality
Most enterprise-grade software is priced out of reach for Philippine SMEs and local businesses. I build production systems at freelance rates — without cutting corners on security, structure, or scalability.
Real systems. Real deployment. Fair rates.Electronics Engineer + Developer
With a BS in Electronics Engineering and real-world hardware background, I bridge the gap between physical systems and software — ideal for automation, IoT, POS integrations, and embedded-connected applications.
Registered ECE • Class of 2012 • USLTYou Own Your System
I build on open, documented stacks — no vendor lock-in, no proprietary black boxes. When the project is done, your team can maintain, extend, and scale it without always calling me back for every change.
Clean code. Full handover. Proper documentation.Web + Mobile from One Freelancer
Need a web system and a mobile app? I cover both — React/Next.js for web, Flutter or React Native for mobile — so you get a unified product from a single point of accountability, not two teams pointing fingers.
Flutter, React Native, PWA — all in scopeDirect Communication. No Middlemen.
You talk directly to the person writing your code. No account managers, no outsourcing to strangers. I give you honest timelines, real progress updates, and say no to scope that will hurt your project — not just take your money.
