ERP & product data support for manufacturers

Cover image for Dutch Website Translation & Technical

Dutch Website Translation & Technical Content Translating website copy, product descriptions, and technical documentation from English into Dutch for an international client operating in the technology sector. The work requires more than language skills alone — understanding the underlying product, its technical context, and the target audience is essential to producing translations that are accurate, natural, and usable. Generic machine output doesn't cut it here; the client needs a native speaker who can think along. What this project covers: Website UI copy and product pages Technical documentation and support content Ongoing collaboration on an hourly basis — not a one-off, but a sustained working relationship Good fit for clients who need: Native Dutch, not translated Dutch Someone who understands what they're translating, not just the words Reliable turnaround and consistent terminology across deliverables Hourly — ongoing availability.

Cover image for Validating and correcting PII annotations

Validating and correcting PII annotations in synthetically generated Dutch-language conversations, covering both nl-NL and nl-BE (Flemish) locales. The work goes beyond simple labelling. Each conversation is reviewed for missing or incorrect entity spans, offset accuracy, and whether every instance of a PII entity is consistently tagged across turns. On top of that, the Dutch language quality is assessed — grammar, naturalness, locale-appropriateness, and conversation coherence — with corrections and explanations provided where needed. PII entity types covered include names, addresses, phone numbers, email addresses, IBANs, ID numbers, dates, usernames, and passwords, each validated against the correct Dutch or Belgian format. Quality targets: inter-annotator agreement above 95%, full locale validity, and self-QC accuracy of 98% or higher. Native Dutch speaker covering both standard Dutch and Flemish — not two separate skill sets, but one annotator who knows the difference.

Cover image for Transcribing and annotating Dutch-language audio

Transcribing and annotating Dutch-language audio for AI speech recognition training at Deepgram, one of the leading speech AI companies. Work involves listening carefully, producing accurate transcripts, and applying consistent annotation according to strict quality guidelines. This is specialist work — not bulk transcription, but quality-controlled annotation used directly to train production speech models. Accuracy and consistency matter more than speed. Native Dutch speaker with genuine familiarity with regional speech patterns, accents, and edge cases that a non-native annotator would likely miss or flag incorrectly.

Cover image for In collaboration with Tektor, ARCh

In collaboration with Tektor, ARCh oversaw cadastral reorganisation and technical drawing updates for three WZH hospital sites in The Hague. The main Sammersbrug site covers 16,000 m², ranking among the largest hospital complexes in Europe. Work included floor plan revision, fire escape redesign, and identification of high-risk zones. A second assignment at Bezuidenhout required historical reconstruction from archival documents. A third commission followed at Nieuw Berkendael, a 7,000 m² facility, confirming WZH's trust in our methodology.

Cover image for This high school in Djilakh

This high school in Djilakh is more than an educational complex. It is a flexible community hub without rigid boundaries. Seven buildings surround a central plaza with a stage and vocational zones open to all residents. Each building features adobe walls, a 7x9m interior, and a shaded porch with the Guna Vault: interlocking terracotta cones forming a barrel vault that reduces interior temperature by 10°C. Local materials ensure sustainability, low maintenance, and a lifespan of over fifty years.

Cover image for Commissioned by De Twee Pauwen

Commissioned by De Twee Pauwen gallery in The Hague, Sedia da Conversazione was conceived for the gallery's upstairs Conversational Room. More than a piece of furniture, it is a spatial essay: a dual seat without visible separation allowing two people to sit side by side while facing different directions, connected by a silent dialogue deepened by an integrated bookshelf beneath the seat. Presented at Dutch Design Week 2025 as part of the Forward Furniture exhibition and featured by Il Sole 24 Ore, it was also introduced to the BNI during their Bike Tour at DDW 2025.

Cover image for I built a Python automation

I built a Python automation tool for logistics that processes shipment Excel files and tracks delivery status automatically. The tool reads tracking numbers from different carriers (DHL eCommerce, DHL Spain, DHL Freight), checks shipment status through APIs or Selenium when APIs are not available, downloads POD documents, and stores them locally. After that, the system uploads POD files to Google Drive and generates a report showing which shipments are delivered, pending, or already uploaded.
