MY STORY

One freelancer. One stack. A hundred tools.

I'm Jeroen. I build software with AI as a freelancer, under the name Alphega. This is why I work that way.

WHO I AM

Senior, solo, and deliberate about it

I've been shipping software for over twenty five years. In recent years I've noticed something shift: AI makes one senior engineer as productive as an entire team. For certain engagements, that opens up a different way of working — with short lines and direct contact with the client.

Alphega stands for excellence. To me that means: sharp problem, pragmatic solution, working software. No sprint poker, no handoffs, no account managers.

I prefer to work on one engagement at a time. It keeps focus sharp and delivery predictable.

APPROACH

Pragmatic, fast, transparent

01

Intro & scope

30-minute video call, no cost. We check fit. I'll be honest if it's not there.

02

Prototype in days

I use AI for discovery, prototyping, and code generation. What took weeks now stands in days.

03

Production with guarantees

Tests, CI/CD, documentation, monitoring. No 'vibe-coded' prototype pretending to be production code.

04

Hand-off or partnership

I don't trap clients. Codebase stays readable, tests run in your own CI, docs live in your repo.

WHAT I BELIEVE

Three convictions that drive my work

01

AI is leverage, not a replacement

AI accelerates a good engineer. It won't save a bad one. I use it as amplification of craft, not as a shortcut.

02

Page-aware AI becomes the default

In two years every user will expect a chatbot to understand what's on the page and which actions are possible. Early adopters win.

03

Solo > agency for scoped work

For scoped AI work, a senior freelancer almost always beats an agency. One contact, one invoice, no context loss.

PROOF

This site is my CV

Everything running here I built and operate myself. Go ahead, try it.

Page-aware chatbot

Knows which page you're on, uses the knowledge base, works in NL and EN, with voice.

RAG knowledge base

Upload, chunking, embeddings, cosine search. Admin UI for content and phonetic corrections.

Multi-provider AI routing

OpenAI, Anthropic and more — with fallback, token budgets, and monitoring.

Built entirely solo

Including Azure deploy, queues, scheduler, security headers, and CSP. One engineer, end to end.
