Change Data collects and combines data on hairdresser appointments, sales, employee schedules, leave, absence, etc. This is combined with machine learning to classify customers, predict churn, and recommend a new appointment with the customer's favorite hairdresser. My task was the maintenance (bug fixes, solving performance issues) and the development of new features of the application. The application consisted of a large set of Azure triggers that scrape external data sources via API calls. The retrieved data was validated and upserted in a MSSQL database. Technologies: Azure, C#, .NET, MSSQL

Ratho BV | May 2013 - Jul 2018

Senior Software Engineer - C# - SQL - Mentoring (Part time side job < 10%)

Ratho beheert de ICT voor onderwijs en mkb. Een van de producten is de 'Ratho Manager' die de gebruikers, groepen, rechten in de lokale Active Directory van de klanten gebruikersvriendelijk en gecontroleerd laat beheren. Technisch gebeurt dat door de gegevens uit Active Directory te halen, te bewerken via de Ratho Manager, en weer terug te zetten in Active Directory. Momenteel coach/mentor ik de (lead) software engineer die de Ratho Manager doorontwikkelt. Voorheen heb ik bijvoorbeeld de specificaties geschreven om product development naar India te outsourcen. Het outsourcen liet te wensen over, vandaar dat een junior software engineer lokaal werd aangenomen. Sindsdien coach en mentor ik hem. In eerste instantie voor technische ondersteuning, later meer in het opzetten van volwassen software ontwikkel processen, en uiteindelijk ook in het coachen en begeleiden van stagiairs. Tool/methods: Active Directory, C#, ASP.NET, MVC, Visual Studio Online, TDD, WCF, Agile/ Scrum, Coaching, Planning, Subversion, Outsourcing.

K3 Retail Nederland | Apr 2017 - Oct 2017

Software Engineer - C# - SQL - REST/API

Terwijl K3 Retail op zoek was naar een of twee vaste medewerkers heb ik een tijdelijk capaciteitsprobleem opgelost. Tot oktober, toen de eerste van de twee was gevonden. K3 Retail maakt kassasystemen met een MSSQL backend, waarin de kassatransacties, maar ook inkoop, voorraad, logistieke processtappen opgeslagen worden. Typische taken waren het schrijven, aanpassen, optimaliseren en debuggen van C# code en SQL queries en het schrijven van web interfaces (met Swagger) zodat we met externe partijen als webshops over winkelvoorraden konden praten en bestellingen konden plaatsen. Soms algemeen, soms klantspecifiek. Daarnaast heb ik onder meer nog het build systeem verbeterd en verbeteringen in het software proces tot stand helpen komen. Mijn volgende beschrijving van een dag uit mijn voormalig Engelstalige profiel laat ik graag staan: 'For instance, in one actual day, I worked on submitting requests to the web interface of an external party, interrupted to help my colleague to debug a legacy C++ application. Then I wrote some exception logging classes in C#. In the afternoon, I wrote some queries to the SQL database and added the results as attributes to a selection dropdown on a html page. With Javascript and jQuery, I created some functions that could update a web form client side based on a newly selected value from the dropdown box.'

ASML | Jul 2013 - Aug 2014

Software Designer

Development for various out-sourced ASML projects, including but not limited to: * V3 reticle introduction, change the reticle marker layouts for many (100+) recipes for various machine types. * QBL sync SBC2 Focus, migrate a delayed project from one strayed software branch to the qualified baseline. 9 months of software development from a different team had 8 weeks delay. Using clever test automation I executed a controlled migration of changes. * TOP-RC2: this project was stagnated in the test phase, because no reliable test results could be created, before I was added to the project. By clarifying the test plan and expected outcomes we progressed in the testing, found and fixed some issues, and finally delivered the project with limited delay. C++, Matlab, Solaris, TDD, ClearCase.

Philips Healthcare | Jan 2011 - Apr 2012

Software Designer - C++ - C#

In XperCT team develop software for medical purposes, especially 'Ablation', to treat cancer and cardiovascular diseases. By injecting needles whose tips can be either frozen or heated, some malign tissues can be eliminated. I helped to create 3D isotherm visualizations of expected temperatures around the needle tip to help the surgeon determine if the right amount of tissue was eliminated. Not too much to keep healthy tissue, not too little to fully eliminate the disease. Technically I used OpenGL 3D libraries where the view could be rotated and I applied sliders for the opacity (transparency) of the ablation zones. Tools and methodologies: C++, OpenGL, C#/.NET, TDD, Agile/Scrum, MFC/UI Design.
