AProfile

Building practical software, end to end.

I'm Yannis Bertels, a Belgium-based developer based in Turnhout. I work end-to-end across full-stack web, mobile and internal tooling, with a soft spot for the parts of software that are usually invisible — automations, migrations, internal CLIs and the quiet plumbing that makes a system reliable in the long run.

Most of what I build lives behind the scenes. Hospital pharmacy tooling. Migration pipelines. AD-bound licence utilities. The kind of software measured by whether someone notices it less over time. AZEC Digital is the umbrella for that work — my personal studio identity for the things I build, ship and keep iterating on.

On the product side, I lean into AI integrations, voice interfaces and sport / climbing technology — the projects I keep coming back to in my own time. They're how I keep my edges sharp on the parts of the stack the day job doesn't always touch.

BRelevant background

Work that shaped how I build.

Three roles, very different worlds — what each one actually taught me, not what fits on a CV line.

Software Engineering Internship

AZ Turnhout — regional hospital

Internship in the pharmacy department at AZ Turnhout. End-to-end build of the internal tooling around their bereidings-logboek — a SQL Server back-end with a repository layer of stored procedures, a Next.js front-end for daily use, a Python pipeline that migrated the legacy FileMaker data into the new schema, and a small PowerShell tool for AD-bound Microsoft 365 licence management.

What it actually taught me: how internal software is used in practice. Non-technical users, fragile existing workflows, and a strong need for idempotent migrations, audit-friendly logging and a UI that maps onto the paper rhythm people already trust. Most of the value was in the unglamorous parts — making the flow not break, not in shipping new features.

  • 2023 — 2024Support

    First Line Support

    CMC

    First-line IT support — diagnosing incidents, walking non-technical users through fixes, and translating vague problem reports into clear next steps. Where I learned to listen first and reach for the keyboard second.

  • SeasonalCoaching

    Snowboard Instructor · Animator

    Ski & Snowboard Kempen

    Teaching snowboard groups across all levels. Reading a room, breaking complex movements into steps, keeping a group calm and confident. The same soft skills that show up later when explaining a refactor or migration to a non-technical stakeholder.

CEducation

Foundations and fundamentals.

Software engineering training — programming, data, full-stack web and mobile, with applied real-world projects.

  • 2022 — 2025

    Associate Degree · Programmeren

    Thomas More — Geel

    Three-year associate programme focused on software development: object-oriented programming, databases, REST APIs, full-stack web and mobile, and applied real-world projects. Foundation for everything in the studio today.

DTechnical stack

What I actually use.

Five buckets, mapped to the work the studio takes on day-to-day.

01/05Languages

Comfortable across compiled and scripted stacks — typed where it pays off, fast where it doesn't.

  • C#
  • Python
  • TypeScript
  • JavaScript
  • SQL
02/05Frontend

Modern React on web and mobile. Component-driven, responsive by default, accessible where it matters.

  • React
  • Next.js
  • React Native
  • Tailwind
  • TypeScript
03/05Backend & Databases

Relational data models, clean APIs and the wiring that holds them together — from .NET services to Node-backed Next.js routes.

  • .NET
  • Entity Framework
  • SQL Server
  • PostgreSQL
  • Prisma ORM
  • REST APIs
04/05Automation & Tooling

Small scripts, internal CLIs and the quiet infrastructure that compounds — Git workflows, PowerShell utilities, idempotent migrations.

  • PowerShell
  • Git / GitHub
  • CLI scripts
  • Migrations
05/05AI & APIs

LLM-powered features shipped into real products — structured tool use, voice agents, prompt design and the glue around third-party APIs.

  • OpenAI API
  • LLM tool use
  • Voice agents
  • Prompt design
EProject shelf

Things I've built.

Pulled live from the project index — swipe through to see every case, internal and personal. New entries land here automatically.

FFocus

Where I gravitate.

The corners of the stack the work keeps pulling me back to.

01

Internal tooling

Domain-shaped apps that map onto the real workflow of the people using them — not generic admin panels.

02

Automation

Small CLIs, idempotent migrations, scheduled jobs. The quiet leverage that pays compounding returns.

03

AI integrations

LLM tool use, voice agents and assistants wired into actual products — not chat demos.

04

Polished interfaces

Editorial UI, strong typography, restrained motion. The details that decide whether software feels professional.

05

Sport & climbing tech

Personal projects in bouldering, training and movement — the corner of the stack I keep returning to for fun.
