Full-stack web developer in Vienna
I'm Daniel Granzer, a full-stack web developer in Vienna. By day I own the jewellery-focused web portfolio at NCA NewConcept Agentur as web developer & team lead – by night my own platforms and passion projects keep growing.
From frontend to backend to AI integration, I build with attention to detail – ideally in the JavaScript ecosystem. And if you have a project that sparks my interest, I'd love to hear from you.

What I work on
Four layers that make up my days right now – from the job at NCA to what gets built in the evenings.

Web Developer & Team Lead – NCA NewConcept Agentur
Since September 2025 I've been building the Experten platform at NCA NewConcept Agentur with Next.js and Payload CMS. Alongside that I maintain 10+ WordPress-based jewellery websites connected to a central Pimcore PIM – including direct customer contact, from first request to delivery.

Architect of the Experten platform
At NCA I design and build the Experten platform: one central Payload CMS as the brain behind Goldexperten, Verlobungsring-, Trauring- and Uhrenexperten plus Juwelierfinder – including the jeweller hub, lead funnels (GEX/VEX/TEX) and production AI pipelines.

The building continues after hours
Learning doesn't stop at the day job: two of my own products are already live: MunchMatch, where you swipe together to decide what's for dinner, and Pike, a private 90-day fitness league for friends. A new platform for the Austrian market is in the works too. Which is exactly why I stay open to interesting projects – do reach out.

The road here
Bilingual computer science at HTL Spengergasse, a web development diploma from SAE Institute Vienna, then banking IT at Euram Bank – I've been at home between code and systems for several years.

How I work
Directly with me
From the first request to ongoing support you talk to the person who builds your project – no hand-offs, no middle layer.
Writing first, then a call
Requests come in writing first. That way I can judge honestly whether I'm the right fit for your project before we get on a call.
Design and code from one hand
I design and develop myself. What you approve in the design is what goes live in the end.
Clear packages, clear prices
You know what your project costs up front. Any extensions are discussed openly before they come up.
Sounds like the right fit?
With me you talk to the person who builds your website, from the first sentence to the launch.

From banking IT to web development – the stations at a glance. The full details are in my CV.

Strengths & stack
An honest self-assessment and the tools I work with every day.
Self-assessment, not a benchmark.
Selected work
Every project individually designed – from a multi-brand system to an online store.
Juwelierfinder.com
Juwelierfinder is the newest and largest expansion of the Experten platform: instead of a single niche it bundles all Experten directories – gold, engagement rings, wedding rings, watches – into one search engine for jeweller services. Users find the right jeweller by request and region; the next stage is a multi-tenant marketplace where jewellers sell watches and jewellery directly.
MunchMatch.me
MunchMatch ends the endless “what are we eating tonight?”. Up to ten people join a room with a five-letter code, everyone swipes the same deck on their own phone – and the first dish all of them like wins. Nothing to install, no account, free. And it keeps going from there: step-by-step cooking mode, shopping list, a week plan for the household.
Pike90.app
Pike turns 90 days of training with friends into a league. It scores how much each person improves against their own Day-1 numbers – beginners and long-time lifters compete on equal terms. Add a voxel gladiator that grows with your numbers, a weekly quota, a trash-talk feed where proof is mandatory and a full workout tracker. Built for a handful of friends, not for followers.
Experten-Plattform
Multi-brand platform for the jewellery industry in Germany and Austria: one central Payload CMS feeds the brand frontends Goldexperten, Verlobungsringexperten, Trauringexperten, Uhrenexperten and Juwelierfinder from the same data set. Jewellers maintain their profiles through a dedicated hub, brand-specific funnels (GEX, VEX, TEX) turn visitors into warm leads for partner jewellers – and AI pipelines accelerate editorial work and data intake.
Diegoldexperten.com
Diegoldexperten.com was the first brand frontend of the Experten platform: an SEO-strong niche site around gold buying. Live precious-metal prices flow into calculators and charts via cron, sellers find vetted buyers in their region – and the GEX funnel qualifies enquiries step by step into warm leads for partner jewellers.
Dreamcare.at
Shopify e-commerce with a custom theme: integrated payments, flexible variant management and multilingual support. Responsive design for every device.
AI that works inside the product
No buzzword bingo: AI speeds up my development and creates measurable value in my clients' products.
Developing with AI
AI-assisted tooling significantly shortens my iteration cycles – more time for architecture, detail and quality. The result stays hand-checked: every line goes through review, every decision stays mine.
Integrating AI into products
Three AI subsystems run in production on the Experten platform – from a researching content pipeline to data intake. With clear principles: verifiable sources, structured output instead of free-form text, cost tracking per generation, and nothing goes live without human approval.
Content pipeline
Keyword research, web research with real sources, schema-forced article drafts straight into the CMS.
Data intake
Google Maps URL in, verified structured profile draft out – hours become a single review click.
