Wat

Web Development

Bij het merendeel van de projecten heb ik een rol van full-stack developer en maak ik dynamische webapplicaties op maat basis van specificaties van de klant. Webprojecten zijn divers, maar omvatten meerdere projecten van een grote oliemaatschappij, een bestelplatform voor restaurants, een marktplaats voor kunstenaars, een community met facturatie, een poppodium met ticketing, een (loyalty) card programma, evenement promotie, deelnemer registratie, etc.

Grafisch ontwerp

Met een essentiële set vaardigheden en de juiste software, zoals Photoshop, Illustrator en InDesign kan bijna alles worden ontwikkeld in print en online. Mijn ervaring omvat het publiceren van boeken, magazines, posters, flyers, gepersonaliseerde prints (uitnodigingen / badges / direct mailings), instore displays, magazine- en krantadvertenties, logo ontwerpen, technische tekeningen, etc.

Digitale media / AV

Digitale media verwijst vaak naar websites, maar is wat breder en omvat ook congres presentaties, narrow casting en outdoor advertising. Ik heb uitgebreide ervaring met het maken van Powerpoint presentaties voor internationale bedrijfsevenementen, zowel voor medewerkers als externe klanten. Ik kan assisteren bij het vormgeven van presentaties en bijvoorbeeld helpen met het maken van video animaties en bewerken van audio.




Technische skills

Hieronder staan technologieën en talen die ik vaak gebruik. Omdat de mogelijkheden breder zijn dan de applicaties waarvoor ik ze heb gebruikt, is geen enkele vaardigheid 100%. Praktisch gezien echter, als een project functionaliteit vereist die ik nog niet eerder heb gebouwd, ben ik er vrij zeker van dat ik erachter kan komen. Vanuit praktisch oogpunt kan ik aan de diverse wensen en eisen voldoen die langskomen bij de onwtikkeling van webapplicaties .

Design Skills

DTP en grafisch ontwerp hebben weinig geheimen, het is wat ik al jaren doe. Als onderdeel van webdesigns, desktop publishing en digitale presentaties. Zo nu en dan eveneens wat videobewerking, dus ik kan een logo animeren of een After Effects-template bewerken om een mooie videopresentatie of webpromo te maken, maar ik ben geen videospecialist.

Interested to know more?

My recent portfolio is the tip of the iceberg of what I've made over the years, but I hope it serves as a first impression. Basically I work every day on a variety of projects and I do not update my portfolio that frequently. So if you're interested to know more or have something special in mind, I can be more specific and perhaps show more recent projects of ones with more relevance.

Yes, I would like to know more

Side-experience and projects

Not necessarilly relevant but I do have side-experience and projects. E.g. trading goods and running an adminstration, helping a cardboard box company and an artist with their Wordpress sites, shipping packages, generating and scanning barcodes (KIX, EAN-18, etc), QRC and RFID/NFC tags, stocktrading and fetching/analyzing live data from NASDAQ / NYSE stocks, narrowcasting and I happen to have a modular 25mm tube system for constructing stuff and a variety of promotional displays for creating presentations during trade shows.

The things above are probably off topic to mention, but perhaps nice-to-know, it may very well become handy or spark an idea ... just feel free to drop me a line.

The benefit of 20+ years experience

As one of the benefits of experience I maintain an ever growing code library for repetitive or common tasks. E.g. generating POCO/OOP Classes and Methods based on database schemas and tables using reflection, scraping all e-mail adresses or product data from URLs, copying via FTP, Regex input validations, user authentication, invoicing, exception handling, API integrations, string manipulations, file/image uploading and manipulations such as format conversions and resizing, creating cronjobs / scheduled tasks, migrating and converting between data-formats such as SQL Server/MySQL/XML/JSON/Excel/CSV. Just to name of few examples.

Some projects and scripts took a lot of time and resources, debugging and incremental steps and fine-tuning to build. Expensive stuff if you consider the time spent and some scripts are really quite elegant for being generic and optimized, object oriented and scalable. Perhaps to time-consuming to even consider building from scratch for an individual project, but quite a nice powerful cart of tools to have ready to work with.

Yes, I want to benefit from experience

Flexible, satisfied and loyal

In terms of working together and contracts I am pretty flexible. My current part-time (0.55 fte) job actually started as a freelance assignment and after completing the webapplication I was simply offered a permanent contract. I was happy to accept the offer, 14 years ago and have been happy since. If you look at my work experience, you can also see my other job lasted 20 years. So I am pretty loyal and basically clients and employers have always been statisfied with the work I do. I have references to support that if you would like them.

My ambition is to work 50% as an employee (current job) and 50% as a freelancer and besides work on side-projects and invest part of the proceeds in a sustainability non-profit.
