Computer Engineer specializing in conflict-resolution APIs, on-device neural networks, and cross-platform mobile apps.
Featured Work
Systems built across distributed APIs, edge computer vision, cross-platform mobile, and enterprise platforms.
n8n AI-Powered Email Processing Pipeline
Automated inbound Gmail ingestion using OpenAI to classify email categories, managing Gmail labels, logging senders to Google Sheets, and archiving attachments to Google Drive in parallel.
n8n Telegram Receipt Processing & Expense Logging Engine
Intercepts mobile receipt photos via Telegram Webhook, uses Google Gemini multimodal vision (temp=0) to extract merchant, amount, and date into Google Sheets, and archives timestamped receipts in Google Drive.
Enterprise Online Secured Payroll Web Application
A full-stack, enterprise-grade payroll web app with Next.js 14, FastAPI (Python), TailwindCSS, and PostgreSQL/SQLite. Automates BIR Withholding Tax calculations, statutory contribution tables (SSS 2025, PhilHealth 5%, Pag-IBIG Circular 460), AES-256 field encryption, and 1-payslip-per-page print exports.
LearnMate (Mobile-Based Android App)
An Android app to streamline remote learning with session booking, messaging, and video conferencing.
Wood Knot Detection App
An on-device, real-time app identifying wood knots using a YOLOv8 model trained on 10,000+ images, optimized via ONNX, and run on TensorFlow Lite.
Capstone: Braille Haptic Reader
An OCR-to-Braille translation pipeline on Raspberry Pi using YOLOv5 for visually impaired users.
Custom Payroll Management System
A bespoke desktop payroll system using Python and PyQt for precise, efficient financial management.
Work Experience
Engineering impact, system design achievements, and enterprise software deployments across industry roles.
- Delivered low-latency video and messaging for two user roles on LearnMate, a cross-platform tutoring app, by designing the Firebase data model, authentication and role-based access, and implementing WebRTC signalling. Dart, Flutter, Firebase.
- Achieved on-device inference for Wood Knot Detection as sole engineer, by training a YOLOv8 detector on a 12,000-image dataset and building the ONNX-to-TFLite pipeline. Python, TensorFlow Lite.
- Cut document and certificate reconciliation from three days to under four hours by designing a normalized PostgreSQL schema and building the tracking system that replaced a shared-spreadsheet process, with authentication and role-based access control across three user tiers.
- Removed 15+ hours of weekly manual data entry from a payroll cycle covering 50+ employees by building a payroll application end to end (Python, PyQt6), automating computation, statutory deductions and payslip generation.
- Shipped to production across two live systems with zero downtime by owning the full Git workflow — feature branching, code review and versioned releases.
- Kept court operations running for 10+ daily staff through repeated network outages by building an offline-first desktop client with automated cloud synchronization.
- Reconciled 1,000+ legal records after outages with zero data loss by engineering bi-directional sync with conflict resolution between offline clients and the live database.
