Selected work

2024 — 2026

AI Investment Platform

FinTech · Private beta

A multi-asset investment platform with AI-assisted analysis, real-time market intelligence, and professional-grade risk controls. Built for retail investors who want institutional-quality tooling. Live in private beta with an invited user base.

Real-Time Fact Checker

Civic Tech · Private

A mobile app for iOS and Android. Share any link or screenshot from any app via the system share sheet. Within seconds, on-device classification triages the claim, and a backend NLP + RAG pipeline checks it against trusted Philippine fact-checking sources. Verdicts come back as Green (verified), Red (debunked), or Gray (needs review), and verified results auto-publish as articles anyone can browse.

Autopilot Sales CRM

SaaS · Private

A modern CRM that takes over the boring parts of sales like cold outreach, drip sequences, and follow-ups, while your team focuses on closing. AI drafts personalized emails. Follow-ups stay in the same Gmail thread so prospects see one conversation, not five.

Voter Intelligence Platform

Civic Tech · In development

A platform that puts every Philippine politician's full track record in one place: bills they authored, controversies that follow them, family connections, and how they actually voted. Built on official records and fact-checked sources, so voters decide on data, not campaign jingles.

Sari-Sari Store POS

Retail · Desktop · Private

A point-of-sale system built specifically for Philippine sari-sari stores. Works through brownouts, turns any phone into a backup scanner, and is engineered to catch the cash that quietly disappears with discrepancy alerts, immutable logs, and daily snapshots that can't be edited away.

What I
do.

Four things, done properly. Every engagement ends with software running in production — not a slide deck.

(01)

AI-powered chatbots

Smart chatbots trained on your actual business — products, prices, policies. They answer accurately 24/7, then step aside the moment your team replies.

For businesses drowning in customer inquiries
(02)

Custom web platforms

Software built around how your team actually works — CRMs, dashboards, point-of-sale, internal tools. One platform instead of five subscriptions.

For teams tired of duct-taping tools together
(03)

Workflow automation

Reminders that send themselves. Payments that verify automatically. Approvals reduced to a single tap. Your people focus on real work.

For operations that waste hours on busywork
(04)

Multi-channel integration

WhatsApp, Messenger, Instagram, LINE, email — every customer message in one inbox. One screen for every conversation.

For businesses juggling five messaging apps

Experience

Full Stack Software Engineer

Control Flow Labs (Startup) · Singapore
  • Centralized AI Communication Hub: Developed a cross-platform interface unifying WhatsApp, Messenger, Instagram, and LINE into a single interface. Businesses manage every customer interaction without switching platforms, which streamlines support and sales workflows.
  • 24/7 Automation with Smart "Auto-Off" Logic: Built an AI-enabled system for 24/7 instant customer engagement. Implemented logic that automatically turns off the AI chatbot the moment a customer service representative starts replying, keeping the handoff from AI to human support seamless.
  • Automated Appointment Reminders: Engineered a background task system using Celery to send automated reminders to clients for booked appointments. Scheduling got tighter and fewer bookings slipped through.
  • AI Vision Payment Verification: Created an AI-integrated system that uses AI vision to scan receipt images for real-time payment validation. Verified payments are intelligently routed to the correct team members, cutting manual workload.
  • RAG Pipeline Implementation: Deployed Retrieval-Augmented Generation (RAG) to connect LLMs with external knowledge bases. This ensures the AI provides highly accurate, context-aware responses to user inquiries.
  • Workflow Automation & CRM Development: Led the end-to-end development of a centralized CRM, focusing on operational efficiency, replacing complex manual processes with simplified one-click workflows for approvals and denials that need minimal input and speed up daily tasks.
  • Platform Credit System: Designed a secure virtual currency and top-up system with voucher support for scalable transaction handling and promotions.
  • RFQ Workflow Automation: Built a 4-workflow n8n system orchestrating LangChain agents (Gemini + OpenAI), Microsoft Outlook, and Postgres to automate order intake, vendor reply classification, report generation, and scheduled fallback reporting, replacing manual triage with an autonomous loop.
