HIRE AN AI FULL STACK DEVELOPER_
Nine-plus years shipping fintech, enterprise platforms and production AI systems — Metro Manila, Philippines, working with teams worldwide. These are the four things clients hire me for.
[02] AI AGENTS
AI AGENTS & WORKFLOW AUTOMATION
Autonomous multi-agent systems and n8n-based automation with real guardrails — the pattern behind Chatflowgate and the agent platforms I built for a Fortune 500 telco.
[ N8N & AUTOMATION CONSULTING → ][03] FULL STACK
FULL-STACK PRODUCT ENGINEERING
React, Next.js, Node and Java Spring Boot — server-rendered frontends and typed APIs, like the SSR migration that cut first paint 40% on a national-scale mobile wallet.
[ HOW THE 40% HAPPENED → ][04] CLOUD
CLOUD ARCHITECTURE & HARDENING
AWS, GCP, Kubernetes, serverless and identity — including AWS Lambda architecture and Okta SSO for 10,000+ enterprise users with ops cost down 25%.
// COMMON QUESTIONS
How do engagements work?
Contract and remote. Scoped projects (a pipeline, a migration, an integration) or an ongoing fractional role on your team — whichever fits the problem. Every engagement starts with a short call to define scope before anything is billed.
What timezone do you work in?
GMT+8 (Metro Manila, Philippines). That gives full overlap with APAC and Australia, mornings with Europe, and evenings with US time zones — I have shipped for North American teams (Telus International, Accenture) for years on that overlap.
What stack do you work with?
React, Next.js, Node.js, Java Spring Boot and Python on AWS, GCP and Kubernetes. On the AI side: LLM copilots, RAG pipelines, agent frameworks and n8n automation, wired into real products rather than demos.
How do I start?
Use the contact form or email [email protected] with a couple of lines about what you are shipping and where it hurts. I usually reply within 24 hours.
