### Introduction

I'm Rodruey (rod-ri) 👋
I design and build AI solutions. And I create my own products and share them online!

Applied AI Engineer · AI Implementation · AI Automation Specialist
Based in the Philippines, working with people all over the world.

### 01 — Who I am

I'm a problem solver, and I'm really good at it.

I can walk into a business, spot where AI can make a difference, and turn it into results, whether that's time saved, efficiency, growth, and so much more.

My story is the greatest asset I have. I started in civil engineering, moved into data, then automation, then AI, and that stacked path lets me look at problems from angles others can't see. I can explain complex AI concepts in simple terms, and I keep honing my craft, my knowledge, and my skills so I can be someone you can trust.

Above all, I just love what I do!

Six DataCamp certifications in data and AI, a degree in civil engineering, a published research paper, and courses in marketing, e-commerce, and more. The rest is on the resume (https://rodrueysimbul.com/resume/).

### 02 — What I build

Mostly, three kinds of things.

- **AI solutions for teams and businesses.** AI applications, automation, and software that take hours of manual work off a team, with AI doing the judgment someone used to do by hand.
- **Products of my own.** Some free, some paid, some built just to learn how.
- **Personal learning.** Content creation, storytelling, design engineering, and really just expanding my skill set and growing as a person.

### 03 — What I've built

Everything here shipped, is still running, or taught me something.

#### AI solutions for teams and businesses

**Production Dashboard Suite** — Five live dashboards on a factory floor.
A manufacturing client's numbers sat locked inside a legacy ERP nobody could see into. Now the data gets pulled out, cleaned up, and put on 40-inch 4K screens across the office, machine shop, assembly, finishing, and vehicle tracking. A system nobody can see is a system people keep checking by hand. One Next.js codebase. Live ERP integration runs six reports in parallel with `Promise.allSettled`, with mutex-protected token refresh and automatic retry. A custom circle-packing layout for the office view, and a single CSS-transform scaling system that keeps every layout exact from 4K down to tablet. Each dashboard ships with a `CLAUDE.md` documenting its architecture, data flow, and invariants.
When: 2025 to now. Built with: Next.js, TypeScript, React-Leaflet, ERP API, Claude Code.

**Strategic Digital Infrastructure** — One internal app in place of a pile of manual workflows.
A cross-platform internal app for a design firm, on iOS, Android, and desktop, replacing fragmented manual workflows. Offline-first with ERP sync, full CI/CD pipelines, and careful data cleaning and request handling underneath.
When: October 2025 to now. Built with: Cross-platform, CI/CD, ERP API, Claude Code.

**HubSpot AI Automation** — Days of prospect research, down to fifteen minutes.
Prospect research that used to take a team several days, started with two clicks inside HubSpot. A generative AI pipeline delivers a structured brief the same morning it's asked for. Result: several days down to under 15 minutes per brief.
When: July to August 2025. Built with: n8n, HubSpot, Slack.

**Email Handler AI System** — Email that handles itself, with a person still in charge.
A multi-agent system that watches a Gmail inbox and runs triage, drafting, and execution in sequence. Three layers of AI verification run before a draft reaches anyone, and nothing sends until a person approves it from their phone on Telegram. Result: zero emails sent without a person approving first.
When: September 2025. Built with: n8n, multi-agent, Gmail, Telegram.

**Integrated AI Workflow** — Three tools that didn't talk, designed into one system.
A content agency ran on Google Workspace, Trello, and Slack, and none of them talked to each other. I designed the system that connects them, with a phased rollout and a forecast of what each phase pays back, so they could approve it one stage at a time. No vendor lock-in, so it survives whatever they switch to next.
When: August 2025. Built with: n8n, Google Workspace, Trello, Slack.

**AI Judge** — Prompt development as a process, not trial and error.
Three specialised agents: one refines a prompt, one attacks it with adversarial stress tests, one validates what survives. Trial-and-error prompt work becomes a structured, automated loop with feedback you can measure.
When: August to September 2025. Built with: Multi-agent, red teaming, n8n.

#### Products of my own

**LawMatch** — Find the Philippine law that protects you.
A free, open-source tool for Filipinos. Describe your legal problem in plain language and get matched to the exact statute. Not a hallucinated summary: the law itself, with section and citations. Result: 16,000+ statutes indexed across 140,000+ searchable sections. Hybrid BM25 and semantic search across Republic Acts, Presidential Decrees, Executive Orders, Batas Pambansa, and Commonwealth Acts. No login. Free forever. The thesis is simple: laws are public data, every country publishes them, we just make them findable.
When: 2026 to now. Built with: Python, SQLite FTS5, Next.js, Docker, Hugging Face.

**FreelanceDesk** — Invoices, proposals, and contracts in under two minutes.
A Chrome extension that lets freelancers make professional invoices, proposals, contracts, NDAs, and quotes with no signup, no backend, and no data leaving the browser. Result: one-time $49, in place of $200 to $400 a year in subscriptions. Offline-first with local AES-256 encryption. Five document types with nine visual styles each, 45 templates, and a Brand Kit that puts your logo, colors, and fonts on everything. Built with Claude Code across the whole lifecycle, plus a companion content site that brings in organic traffic.
When: 2025 to now. Built with: Chrome Extension, Next.js, Tailwind, Claude Code.
Site: https://freelancedesk.online

**Locked-In Café** — A speed bump for distraction, not a wall.
A calm anti-distraction tool that catches the reflex instead of walling it off. Type a distracting site and you land on a near-black page asking if this is where you meant to go. One keystroke and you're back to work. A short reflective prompt grants a timed pass, then it quietly re-blocks. An honest focus dashboard shows measured stats: resist rate, time on caught sites, the reasons you typed. Everything stays on your machine. No accounts, no servers, no tracking.
Built with: Manifest V3, declarativeNetRequest, Claude Code.
Chrome Web Store: https://chromewebstore.google.com/detail/aofmceegegcdifbiapflannblpadekbi

**Claude Intelligence Ecosystem** — Lead generation and outreach, end to end, as Claude skills.
A suite of connected Claude skills. One drives Playwright through MCP across YouTube, Google Maps, and websites, extracting only verified contact information from public URLs. No email guessing, and full deduplication across runs. Another turns those leads into personalised Gmail drafts, with a person reviewing before anything sends.
When: 2025 to now. Built with: Claude Code, MCP, Playwright, Gmail, n8n.

**Claude Blog Production** — One command ships a verified, indexed blog post.
Six coordinated Claude skills covering a seven-day content strategy, keyword research, MDX writing, SEO and E-E-A-T quality gates, and auto-indexing through the Google Indexing API and Bing IndexNow on every deploy.
When: 2025 to now. Built with: Claude Code, MDX, SEO.

**PriceFlow** — A pricing engine for short-term rental hosts.
A full-stack SaaS that pairs a deterministic rules engine with AI market intelligence (events, weather, holidays, occupancy trends) to recommend nightly prices across a 60-day horizon. Built solo as a deep dive into hybrid pricing architecture. Not for sale. A sub-50ms rules engine with weekly AI insights per market, seven pricing factors, and min and max guardrails. Better Auth, Stripe subscriptions, Drizzle ORM on Neon Postgres, and a mock Airbnb integration.
Built with: Next.js, Postgres, Stripe, Drizzle.
Demo: https://youtu.be/6l3XGmwahrQ

**Million Dollar Chickens** — My income streams, racing to a million.
A gamified income tracker. Each chicken is an income stream, active or passive, racing toward $1M on a side-scrolling pixel track. Around it: to-dos, a Pomodoro timer, daily goals, streaks, and a journal with a time capsule. Built solo as a motivation engine. Canvas pixel art with a particle engine and chicken moods, the timer in a web worker, push notifications through Vercel cron, and Supabase Postgres with row-level security. 12,460 lines across five phases.
Built with: Next.js, Supabase, Canvas, Zustand.

**AI Video Processing System** — Long videos into short clips, automatically.
An end-to-end system that turns long-form video into short-form clips. Whisper for speech, TransNetV2 for shot boundaries, and custom adaptive weighting with fuzzy logic deciding what makes the cut. Result: 35 to 40 minutes instead of 2 to 3 hours, with 70 to 80% of picks matching a human editor's.
When: October 2024 to January 2025. Built with: Python, Whisper, TransNetV2.

The code lives on GitHub (https://github.com/raiyara), open models and demos on Hugging Face (https://huggingface.co/Raiyara), launches on Product Hunt (https://www.producthunt.com/@rodruey_simbul).

### 04 — How I got here

None of it was planned. But every step was preparing me for the next one. I just didn't know it at the time.

**Civil engineering** — Where I discovered my passion for teaching and found my edge: I learn insanely fast, I can apply what I learn right away, and I look at problems from different angles. Plus a lot of math and problem solving.
BS Civil Engineering, Don Honorio Ventura State University, 2020 to 2025. Led and published a study on soil permeability.

**Data** — I realized I wasn't cut out for structures. I was drawn to insights, and there's something almost mystifying about data. It's also the foundation of all AI work. In civil engineering I worked with foundations in the physical world. Data turned out to be the digital one. So I learned everything I could…
Certified by DataCamp: Data Literacy (2024), SQL Associate (2024), Data Analyst Associate (2024), Python Data Associate (2025).

**AI** — This is where I found my calling. I needed to automate a process in my own business, stumbled into AI automation, and from there things just snowballed. I built all kinds of projects, then advised on and built AI solutions for businesses: strategic plans, roadmaps, audits, RAG systems, AI applications, and so much more. And the one thread running through all of it? A solution to a problem.
Certified by DataCamp: AI Fundamentals (2024), AI Engineer for Data Scientists Associate (2025).

**Software and products** — AI changes fast, and for a lot of it there's no clear roadmap. I wanted to be the best at this and deliver solutions and products I could be proud of. So I learned proper software development by building actual software: evaluation and reliability practices, full-stack development, APIs and databases, CI/CD and deployment, authentication and payments, and documentation the next person can pick up.
FreelanceDesk, Locked-In Café, LawMatch, and software for clients. 2025 to now.

**AI solutions** — Now I use the entirety of my skill set to design and build AI solutions for businesses, with a focus on evaluation and reliability. 2026.

**Building in public** — I also document the work and teach it, and I want to keep growing as a speaker and build a bigger presence online. In short, I want to turn my five-star social skills into ten stars! YouTube, LinkedIn, and X.

### 05 — What I'm doing now (updated September 2026)

- Building: Business infrastructure on n8n.
- Learning: Mathematics for Machine Learning.
- Reading: *AI Engineering*, by Chip Huyen.
- Open to: New projects. If you have an AI solution you want built for your business, email rodruey@rodrueysimbul.com.

### 06 — Off the keyboard

- Music: I play five different instruments. The "86" soundtrack is my favorite playlist. I love orchestral music.
- Games: Mobile games — Wuthering Waves, and mostly Wild Rift.
- Books: I read tons of them. Favorite genre: Eastern fantasy.
- Staying active: I run, bike, swim, lift, and a lot more.

### 07 — Where I'm going

More products of my own, more skills (going deeper into design engineering), a deeper understanding of AI engineering, and getting better at content creation. And above all, to be worthy of the trust people give me when we work together.

I build. I learn. I experiment. I ship. I document. I share. I keep moving.
