BIO

The Story Behind the Journey

Engineering philosophy, specialization & context

FULL-STACK · AI / RAG · DATA

Software engineer with a full-stack background and a track record of building secure, enterprise-grade web applications. I graduated from HBO-ICT Software Engineering at the Hogeschool van Amsterdam, where I specialised across full-stack web, mobile, big data and AI, completing my degree with a RAG/LLM integration proof of concept at DEVENTit. I worked on the multi-tenant Atlantis platform until August 2026, contributing to feature development and maintenance.

From fundamentals to full stack

My degree started with programming fundamentals, object-oriented design and databases, then moved into full-stack team projects each semester: a matching platform built with HTML, CSS and JavaScript (Fasten Your Seatbelts), a Node.js and Express application with MySQL and an MVC-style architecture (PAD), and a greenhouse management application built with Angular and Spring Boot and secured with JWT (Climate Cleanup, EWA).

Specialising: mobile, data and AI

In the later stage of the programme I specialised further: an Android Mobile Development semester with Kotlin and Jetpack Compose, a Big Data minor building a production-oriented analytics platform with an external company (Arkive) using Flask, Dash and Docker, and a Software Engineering specialisation semester covering design patterns, testing and containerised CI/CD.

Graduation: secure RAG integration

My graduation project at DEVENTit investigated how to securely integrate a large language model into Atlantis, a multi-tenant collection management system, without bypassing its strict role-based access control. I designed an indexing pipeline and a hybrid retrieval pipeline combining dense vector embeddings with BM25 keyword search, delivering a proof of concept where the RAG service interprets questions and retrieves candidates while Atlantis remains responsible for authorizing results.

Today

My experience includes working as a software engineer at DEVENTit until August 2026, earlier part-time engineering and internships on the same product, and a cross-platform application development internship using .NET MAUI at FacilityApps.
