};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.

What Clients Say
Businesses that run their daily operations on systems I built.
"Before DentalReach, patient records were scattered across logbooks and my front desk spent hours on scheduling and billing. Now appointments, treatment history, and invoices live in one screen — admin work is noticeably lighter and patients get seen on time."
"Checkout used to mean handwritten receipts, and closing time meant an hour of tallying. With the POS, we scan, print the receipt, and the end-of-day sales report is ready in minutes — I finally trust my numbers."
"Payroll used to eat my whole week. Now attendance, leave requests, and SSS/PhilHealth/Pag-IBIG deductions are computed automatically and pay slips print in seconds. It paid for itself in the first payroll run."
