About me
I build web applications, custom CRMs and business automations. My work covers requirements, development, testing and deployment.
I develop operations dashboards, API integrations and 3D configurators. I help teams connect existing tools and reduce manual data entry. I use AI for tasks that involve interpreting text or documents.
Projects include Frankie CRM, RoofPVCalculator, price monitoring, a store auditor, a rental dashboard and Bacteria Run. Screens use anonymized demo data. The Judler dashboard is labelled as a concept visualization.
Technologies: TypeScript, React, Next.js, Node.js, Python, FastAPI, Django, SQL and Docker.
We agree on the scope, price and outcome before each stage. The initial discussion and outline are free. When an existing tool or a simple integration is enough, I recommend it.

Portfolio
A custom CRM tailored to the company's workflows. It connects sales, inventory, quotes and invoicing. Automated data exchange supports order processing and reduces repetitive tasks, giving the team one place to manage daily operations.
An automated tool for reviewing online stores. It checks product pages, links and selected pricing and manufacturer information. A single report brings the findings together, reducing manual page checks and helping the team plan fixes.
A server-based system for supervising AI agents. It combines tasks, model selection, approvals and cost controls. Saved progress supports recovery after interruptions, reducing manual supervision. The image shows a concept for the dashboard.
An AI agent working directly in the VS Code terminal. It combines queued instructions, project tools and saved progress. Developers can adjust a task while it runs, without moving context between a separate chat and their development environment.
A tool that collects water quality reports from websites, PDFs and spreadsheets. It standardizes parameter names, units and dates, then combines results in one Excel file. Automated preparation reduces manual copying and makes comparisons easier.
A PV roof configurator built from scratch. Satellite mapping and a 3D editor let customers calculate roof area, material quantities and purchase costs. Automated calculations reduce quoting work for the sales team and help customers compare options.
A system for monitoring product prices across competing stores. It finds offers, checks product variants and records price changes. Reports and alerts replace repeated manual comparisons and give the sales team data for pricing decisions.
A browser game with custom movement physics, rankings and saved progress. Gameplay connects to a shop, vehicles and character customization. Earning coins and unlocking items gives players new goals and reasons to return.
A demonstration application for rental businesses. It brings together vehicles, customers, rentals and service dates. Shared availability and booking data helps staff plan handovers and returns without checking several separate records.
A website presenting my services and projects. Switchable screens show how the applications work, while a form helps clients describe their requirements. A custom generator and tests support updates. The site runs on my own server.
