Excelsior AI Manager previewFeatured
AI ProductLive

Excelsior AI Manager

A full team of AI agents working 24/7 — monitoring, selling, securing, and growing your business while you sleep.

The Problem

Hiring a full operations team is expensive, and most businesses run on disjointed tools that nobody watches after hours. Websites go down unnoticed, leads go cold, security threats go undetected, and content stops being published — because there is no one assigned to watch them around the clock.

The Solution

Excelsior AI Manager is a 24/7 team of eight AI agents — Operations, Sales, Security, SEO, Marketing, Developer, HR, and Content — that watch your systems, capture and follow up leads, block attacks, audit your site, track marketing, and plan content around the clock. Every agent reports in plain language, and nothing is sent or published without your approval. Built on your own infrastructure — no monthly SaaS fees.

AI ProductLive

Lex — Excelsior AI Assistant

Handles client inquiries 24/7. Zero staffing cost.

The Problem

Businesses lose leads after hours because no one is available to handle inquiries. Every unanswered message is a missed opportunity — but hiring someone just for initial qualification is not practical.

The Solution

Lex is a branded AI agent that lives on your website and handles client inquiries 24/7 — no staffing cost, no missed leads. It captures and scores every lead, saves the full conversation, and emails your team the moment a new inquiry comes in. Multilingual and always-on: it answers questions, qualifies visitors, and hands off hot prospects for a live conversation. Deployed on the Excelsior website with conversation history stored securely — built with React, Claude, Supabase, and Resend, available any time with no additional headcount.

SnipSnap — Screen Capture & Annotation previewFeatured
Internal ToolClient Build

SnipSnap — Screen Capture & Annotation

Personal screen capture and annotation tool — built for my own workflow, with commercial potential after full testing.

The Problem

I needed a capable screen capture and annotation tool for daily documentation and client work. The built-in Snipping Tool was too limited — no annotation depth, no window detection, no delay timer, no PDF output. Subscription tools like Snagit were overkill and added recurring cost for what should be a one-time build.

The Solution

Custom Electron desktop app built to my exact workflow: region, window, and full-screen capture with crosshair overlay, magnifier loupe, and automatic window detection. 15+ annotation tools including rectangle, ellipse, arrow, line, freehand pen, text, step counter, callout, highlight, stamp, blur, magnify, fill, eraser, and crop. Save as PNG, JPEG, or PDF. Copy to clipboard. Launcher window with delay timer (0/3/5/10s), system tray with hotkeys, and a portable EXE — no install, no cloud, no recurring cost. Once fully tested and revised, this may be released commercially.

WhatsApp Business Automation

WhatsApp Business Automation

Auto-reply system that handles lead inquiries on WhatsApp 24/7.

The Problem

Businesses miss leads on WhatsApp when messages go unanswered after hours. Manual responses are slow and inconsistent — no system exists to qualify prospects or route inquiries when the owner is unavailable.

The Solution

n8n workflow automation deployed on a self-managed Hetzner VPS behind Nginx + Let's Encrypt SSL. A custom Node.js proxy handles WhatsApp Cloud API authentication. Smart keyword detection auto-replies with service menus, booking links, and portfolio — 15+ keyword categories including Consultant, SEO, AI, Web Development, and Pricing. No monthly SaaS fees; everything runs on owned infrastructure.

The Solution

Full-stack course platform with 26 modules, 190+ lessons, and 130+ templates. Three-tier access system with authentication, progress tracking, and a community forum. Built entirely using an AI-assisted development approach.

Forex Traders Database

Custom internal platform for managing 100+ forex traders, MT4 accounts, VPS servers, and payment tracking.

The Problem

Managing 100+ forex traders, 170+ MT4 accounts, VPS servers, and payment records across an operation required too many manual spreadsheets with no central view, no payment tracking, and no way to send notices to traders.

The Solution

Built solo using AI-assisted development. Full Node.js + Express app with AES-256 encrypted MT4 credentials, session auth, and rate limiting. Migrated off Render to a self-owned Hetzner Linux VPS — provisioned from scratch with SSH, firewall, Nginx reverse proxy, PM2 process management, and Let's Encrypt SSL. SQLite database persisted on VPS disk.

Excelsior HR Advisor

AI-powered HR counsel for Philippine labor law — available 24/7.

The Problem

SMEs in the Philippines face real labor law compliance exposure but cannot afford retained HR counsel. A single wrong decision on termination, benefits, or contracts becomes a costly legal issue.

The Solution

AI-powered advisor covering 6 HR domains — Labor Law, Compensation, Recruitment, Performance, Employee Relations, and Compliance. Freemium SaaS model. Available any time, at a fraction of the cost of retained HR.

SEO Strategy & Implementation

Business ToolLive

SEO Strategy & Implementation

SEO strategy report, technical implementation, and performance monitoring — for any platform.

The Problem

Websites built on modern frameworks like Next.js lack SEO fundamentals out of the box: no sitemap, no per-page metadata, no structured data, and no social previews. The codebase needs a full implementation — sitemaps, metadata, structured data, and social tags — not just recommendations.

The Solution

A complete SEO service: strategy report delivered, approved strategies implemented. Sitemaps, metadata, structured data, social previews, and Search Console — all baked into your site and verified live.

Excelsior Financial Dashboard

Custom financial visibility — built for how the business actually works.

The Problem

Off-the-shelf financial SaaS costs $500–$1,200 per year and still doesn't fit how a consulting firm actually tracks revenue, expenses, and project-level P&L.

The Solution

Custom real-time financial dashboard with revenue tracking, sales reporting, expense management, and full P&L visibility. Multi-client and multi-user. Built specifically for Excelsior's reporting structure — replacing all SaaS spend.

hermes-ds-balance — Open-Source Hermes Plugin

Free ToolLive

hermes-ds-balance — Open-Source Hermes Plugin

A /balance slash command that shows your live DeepSeek account balance.

The Problem

Hermes (a Nous Research AI agent) tracks usage tokens but never fetches DeepSeek account balances — so anyone running DeepSeek models has no in-session view of what they have left. Checking meant leaving the session and hitting the API by hand.

The Solution

MIT-licensed open-source Hermes plugin that adds a /balance slash command — live DeepSeek balance at a glance, /balance warn for low-balance alerts with a custom threshold, and /balance raw for JSON. Reads the API key from the user's environment, pip-installable via the hermes_agent.plugins entry point, and published on GitHub so any Hermes user can install it.

RC Family Grocery Backoffice

Replacing the logbook — consistent BO item reporting for a Philippine grocery chain.

The Problem

RC Family Grocery's back office items were tracked through manual logbooks and loose references, making reports inconsistent and unreliable. Missing entries and unclear records meant management had no consistent view of BO item movement across branches.

The Solution

Custom web app that centralizes back office item reporting — eliminating the manual logbook and giving management a consistent, reliable reference for every BO item transaction. Built specifically for RC Family Grocery's operational structure.

Excelsior Messenger Bot

Multilingual AI on Facebook Messenger — Tagalog, English, Taglish, and Bisaya.

The Problem

Filipino users engaging with businesses on Facebook Messenger expect responses in their native language. Generic chatbots respond only in English and miss the code-switching (Taglish) and regional language (Bisaya) that Filipino users naturally use.

The Solution

Facebook Messenger bot with multilingual AI responding in Tagalog, English, Taglish, and Bisaya. Detects the user's language automatically and responds in kind. Integrated with the Excelsior brand and deployed as a live channel for business inquiries.

Southroads Auto Website

Dark luxury web presence for a Cebu auto services brand.

The Problem

Southroads — a Talisay, Cebu auto shop offering paint & body repair, detailing, and car display — had no digital presence. Walk-in traffic alone cannot scale a premium auto services brand; a compelling website is the front door.

The Solution

Custom single-page website built from scratch with a dark luxury visual direction: black, red, and gold palette, Montserrat and Cormorant Garamond typography, custom cursor, smooth scroll animations, and a page loader. No framework dependencies — pure HTML, CSS, and JavaScript for maximum performance and zero build overhead.

Secure AI Agent Operations previewFeatured
Internal ToolLive

Secure AI Agent Operations

Give autonomous AI agents the ability to perform real VPS and application operations without unrestricted root access.

The Problem

AI agents can perform increasingly complex infrastructure tasks, but giving an autonomous agent root-level access creates unnecessary risk. A compromised or misdirected agent could potentially access sensitive applications, credentials, databases, or system configuration.

The Solution

Designed and implemented a least-privilege AI operations environment using a dedicated non-root agent account, allowlisted operations, controlled Docker access, protected credentials, restricted deployments, and security validation. The agent can perform approved diagnostics, application management, and controlled deployments while protected systems—including a sensitive FX database—remain outside its authorized operational boundary. Implemented and tested on a production Hetzner VPS: 40+ protected-resource isolation tests passed, 36/36 approved functionality tests passed.

Real Business Problems

My AI-Assisted Coding
Methodology

How I build real software without memorizing syntax. Updated 2026.

“I design the systems that run your business. Then I build them.”

Most developers start from the code. I start from the business problem. With over 20 years of business and HR practice behind every decision, I diagnose the operation, design the system, and use AI as the execution layer.

The result is software that actually fits how a business works.

“You don't need to know everything to build something real. You need clarity, structure, and the discipline to keep iterating.”

My Workflow

Git BashClaudeLocalhost TestSupabase / NeonVercel Deploycron.org
01

Propose Before You Build

No code until the plan is clear. Scope, architecture, and sequence come first. Wasted cycles are eliminated before they start.

02

Feature Branches, Always

Every feature lives on its own branch. Nothing touches master until tested and stable. Production is always protected.

03

Real Database From Day One

Supabase or Neon from the start. No JSON workarounds, no shortcuts. Data structure is the foundation, not an afterthought.

04

Localhost First, Deploy Last

Every correction is tested locally before pushing to Vercel. Nothing goes live until I approve it. The pipeline stays clean and intentional.

05

One AI, Fully Mastered

Standardized on Claude across architecture, code, copy, and strategy. Deep fluency with one tool beats shallow use of many.

06

Document as You Go

Changelogs, architecture notes, and SOPs are built alongside the product. Documentation grows with the work, not after it.

07

Iteration Is the Real Skill

Clear communication and precise problem framing produce better software than memorized syntax. The first output is always a starting point.

08

Security by Default

Every deployment passes a security review before release. Environment variables, database rules, and dependencies are all checked without being asked.

09

Structured Project Memory

Every project carries a CLAUDE.md: a living brief that holds conventions, stack details, branch rules, and session context. Claude Code reads it automatically.

10

Conventional Commits

Every commit follows a structured format: feat, fix, docs, security, refactor. This feeds the changelog automatically and keeps history readable.
