// one engineer, the whole product

I build the Vue / React interfaces, run the Laravel and Postgres behind them, and wire in AI that survives production. Drag the seam below — same feature, both sides of my stack.

01 / What I do

Not a specialist you have to staff around. The whole build.

full_stack.ts

I own the whole build

Eloquent models on Monday. Vue components on Tuesday. Same head. No handoff to lose the intent.

AI that reaches production

RAG that cites its source. Claude, OpenAI, Gemini — plugged into real Laravel endpoints. Automation with guardrails, not vibes.

Interface

Vue 3 and Next.js UIs. Offline-ready PWAs. The layer users actually touch — and I care about how it feels.

Backend

Laravel that doesn't fall over at 100K users. 70% faster APIs. Tests that mean something.

Laravel · Octane · Horizon · Postgres

Infra & Delivery

Dockerised pipelines, Forge/Hetzner deploys, GitHub Actions CI, and the observability so it stays up.

03 / AI & automation

Grounded answers,
not hallucinations

I build retrieval pipelines that cite their source and fall back gracefully when confidence is low — then wrap them in clean Laravel endpoints with 80%+ test coverage.

Claude Code certified — Anthropic, Feb 2026
Retrieval with confidence thresholds — not confident? fall back gracefully instead of hallucinating.
RAG on Pinecone or pgvector, with citations users can actually click.
Agentic automation with n8n, Playwright, and MCP — real guardrails, not demos.
Then wrapped behind a Laravel API you can test like any other endpoint.

Bring me the part no one wants to own.

The API that buckles under load. The frontend that's fallen behind. The AI that only works in the demo. That's the work I like — and I've shipped it at 100K+ users, 99.9% uptime.
