About Johnbert

The person behind the code

AI Solutions Developer, Full Stack Engineer, and WordPress Expert based in the Philippines. I build software that works in production.

The Journey
2018Foundation

WordPress Solutions Architect

Launched career building custom WordPress themes, WooCommerce stores, and plugin ecosystems for local businesses. Learned fast that clients care about outcomes, not code.

2020Scale

Full Stack Developer

Expanded into React, TypeScript, Node.js, and modern SaaS architecture. Delivered 20+ production web apps for clients in the US, UK, and Australia.

2025Intelligence

AI Solutions Developer

Pivoted into AI engineering — LLMs, RAG pipelines, vector databases, and custom agents. Built AI-native products that reduced manual work by 60–80% for clients.

NowPresent

Independent Developer + Consultant

Consulting with startups and SMEs globally. Scope, build, and ship intelligent products end-to-end — from strategy to production-ready deployment.

Philosophy

How I think about building software

I started as a WordPress developer in 2018 — not because WordPress was trendy, but because clients needed working products fast. That grounding taught me something most engineers skip: business outcomes matter more than elegant abstractions.

The evolution to full-stack and then AI wasn't a pivot. It was depth building on depth. Every layer — PHP to TypeScript, REST to GraphQL, static to AI-native — made me a sharper problem-solver. I now bring that full-stack lens to every AI engagement: understanding the business model first, then picking the right tools.

I'm based in the Philippines, fully remote, and have shipped production products for clients in the US, UK, Australia, and Southeast Asia. Async-first by default, with synchronous availability across timezones on request.

What I Believe

Three principles I never compromise

01
Principle 01

Ship fast, iterate smart

A working product in production beats a perfect product in planning. I move with urgency and refine in cycles. Velocity isn't recklessness — it's discipline applied correctly.

Done > perfect.
02
Principle 02Tool, not crutch.

AI is a multiplier, not a replacement

I use AI to amplify craftsmanship — faster builds, smarter solutions, but always with human judgment at the core.

03
Principle 03Truth, then execution.

Clients deserve honesty over hype

I won't tell you what you want to hear. I'll tell you what will actually work — then build it.
