FrenzelTech Shop — Own E-Commerce Software
FrenzelTech Shop is FrenzelTech's own e-commerce software, developed on the Vendure backend with an Angular storefront. The customer runs the software on-premise on their own server: storefront in up to six languages with SSR and SEO, Stripe checkout with cards and TWINT, customer accounts, PDF invoices and an admin UI for products, orders and promotions. FrenzelTech installs and configures the software, the customer fills the shop with their products and uses the software under a recurring licence fee. All data stays on the customer's server.
- FrenzelTech's own software built on Vendure
- Runs on-premise on the customer's server
- Stripe with cards & TWINT, multilingual with SSR & SEO
- Licence model instead of a SaaS plan with revenue share

A good fit if
- your project is clearly scoped and doable in 20 to 60 hours
- the collaboration can run fully remote
- one person on your side can make decisions quickly
- you can provide access and test data at kick-off
Not a fit if
- you are looking for a long-running full-time or staffing engagement
- on-site presence is required
- the scope is meant to stay open and keep growing
- you want to outsource 24/7 operations and on-call duty
All prices exclude VAT and are “from” guide prices. After a free intro call you receive a binding fixed-price quote. Delivery time counts from kick-off, provided access and feedback arrive on time. I take on larger projects when they can be split into stages of this size.
AI & Automation
From clever prompts to production AI systems.
I don't just plug in ChatGPT and call it innovation. I build agents, retrieval systems, evals and guardrails that actually work in production — and I measure the result.
Autonomous AI Agents
Goal-driven agents that plan, use tools, retrieve context and complete real tasks — across CRM, email, internal systems.
Workflow Automation
End-to-end automation: from a Slack message or webhook to a fully orchestrated, AI-assisted business process.
Voice AI Agents
Natural-sounding voice bots that book appointments, qualify leads and handle support — connected to your stack.
AI Video Pipelines
Generate, localize and render brand-consistent video at scale — perfect for marketing, sales enablement and training.
MCP Server Engineering
Expose your tools and data through the Model Context Protocol — securely integrate with Claude, ChatGPT and any modern LLM client.
RAG & Knowledge Systems
Vector search, hybrid retrieval and grounded answers — so your LLMs reason over your data, not hallucinations.
Have a workflow you'd love to automate?
Tell me about the manual process. I'll tell you what an AI agent or n8n workflow can do about it.
Technology
A stack I trust, picked for the job
I use battle-tested tools and modern frameworks. No hype — only what I'd put behind my own name in production.

How I work
Four steps from idea to production
A lean, transparent process. No buzzwords, no theatre — just engineering with clear milestones.
01
Discover
I listen, audit your stack, identify the highest-leverage opportunities and define success metrics.
02
Design
Architecture, data flow, models, UX. I design for clarity, observability and a graceful path to scale.
03
Build
Weekly demos, clean code, real tests. You see progress every week and I ship in tight iterations.
04
Launch & Operate
Deploy, monitor, hand over. You get a system you fully own — including source code and documentation.
Ready when you are
Let's build something serious.
Bring me a workflow, an idea or a pile of legacy code. I'll bring engineering and AI experience.
