Real products. Real users.

I design and build the whole thing — product, interface, and the code underneath.

GGU AdvisorDeck

Production CRM & Analytics OS for a Life Insurance Unit
A real production app with real users: 16 advisors and a unit manager at a Sun Life insurance unit log in daily — it replaced the team's spreadsheet operations end to end. A 12-stage client lifecycle, two-way Google Calendar sync, password-protected AHO Excel imports, award and ADCAN tracking, scheduled email digests, in-app tickets and nudges, a ⌘K command palette and dark mode — built on 110 numbered SQL migrations with row-level security and 163 test files. Screenshots show mock demo data — the unit's real book stays private.

PPVC Pulse

Kiosk-First Attendance, Payroll & Clinic Ops
Attendance and payroll for a working vet clinic. Staff clock in on the front-desk tablet with a face scan or PIN — the phone app can't clock in at all, so nobody punches in from bed and no one covers for a friend. Each teammate gets an illustrated pet sidekick that reacts to their attendance: on time and it's happy, late and it worries, on approved leave it just naps — it never guilt-trips an honest sick day. Behind the cute layer sits a 20-table Postgres backend with row-level security, schedules, leave, emergency callouts, crash-cart-level inventory — and payroll that computes OT, holiday, and night rates itself, then sends PDF payslips in one click: roughly 15 hours of timesheet-tallying and payslip-writing automated away every month (~180 hours a year). Screenshots show mock demo data.

Bayou Detail Co.

Mobile Car-Detailing Booking — Houston, TX
A single-page, mobile-first booking site for a Houston mobile car-detailing business that was taking bookings through a generic form and losing time on every one. Customers pass a ZIP gate, pick one of four flat-price services, pick an hourly slot in the next 7 days, and request a booking — no accounts, no payments. Built end to end in under 4 hours, with validation enforced in the database itself.

ELD Trip Planner

HOS-Compliant Trip Planning & FMCSA Log Generator
Takes a truck driver's trip details and generates a route map with required stops and filled-out FMCSA daily log sheets — fully compliant with federal Hours-of-Service rules (49 CFR §395). Driving time comes from real route durations, fuel and rest stops are snapped to real gas stations and truck stops, and the duty-status grid is hand-drawn as resolution-independent SVG.

Ship it. Watch it.
Fix it. Repeat.

The method
  1. 01Scope
  2. 02Build
  3. 03Ship
  4. 04Observe
  5. 05Iterate

Every project I take runs through the same five stages. Not because process is exciting, but because the stages are where the mistakes hide — and a client who runs a booking desk or a sales unit does not have time for mistakes.

The tools change; the loop doesn't. Build it, test it against a copy of production, watch what real people do with it, fix what the numbers point at.

  1. 01Scope

    Talk to the person who will actually use it.

    Before any code: the real workflow, the real edge cases, the boring spec. Most "features" die here, which is the point.

    OutputOne-page spec · data model · what we are NOT building

    Notebook, calls, a whiteboard
  2. 02Build

    The proven pattern, reshaped for this market.

    Next.js and Supabase for the product, Python and Flask where the logic is heavier. Adapt what already wins in production; skip the clever version.

    OutputWorking app · seeded demo data · README

  3. 03Ship

    Test against a copy of production first.

    Schema changes run through numbered migrations, tested on a local Docker copy of the database before they touch the live one. Recurring jobs and hand-offs go through n8n instead of cron scripts nobody remembers.

    OutputNumbered migrations · tests · n8n automations

  4. 04Observe

    Know what people do — and what breaks — before they tell me.

    PostHog shows which screens get used and where people drop. Sentry catches the exception with the stack trace, the user and the release, usually before the email arrives.

    OutputFunnels · error alerts · in-app bug reports

  5. 05Iterate

    Fix the thing the data points at. Repeat.

    The launch is the start. Weekly: read the numbers, pick the one change that matters, ship it the same way. Claude Code keeps the loop fast.

    OutputChangelog · next spec

Measured every week

Activation, the one funnel that matters for this client, error rate per release, and time from bug report to fix.

Never skipped

Seeded demo data, an empty state that explains itself, a README the next developer can follow, and a rollback path.

About

More than just the code.

I'm a Computer Science student at Emilio Aguinaldo College (DEP Scholar) who builds real products for real people — not just school projects. Outside the terminal, I sing with the college chorale, serve as JPCS Director of Membership — managing our students' memberships all the way up to nationals — and make short-form videos that actually get watched.

I believe the best developers ship things, own the outcome, and keep it honest.

What I reach for.

One flow, five layers. The same tools show up across every project — a small, current set I know well enough to ship on a deadline, from the phone screen to the database.
