Software connected to reality

A portfolio of projects where applications work with real data, physical devices, manufacturing processes or operational workflows. From operator interfaces for industrial machines and real-time video analytics to automating technical processes with AI.

What interests me most in these projects is turning a complex technical problem into a solution that works reliably in real-world operations — not just in a design or with demo data.

Mycronic Pick-and-Place Operator Interface

Real-time touchscreen application used directly by operators on Mycronic PCB assembly machines. I led the frontend delivery and UI/UX direction for a production interface that turns high-frequency machine data into a clear, reliable operating workflow.

We built the entire system from scratch — from designing components in the browser, through testing on the real machine by our team and experienced operators, incorporating their feedback, and finally deploying the application to the machine's Linux environment.

Role: Team Leader · Senior Frontend Engineer · Lead UX/UI
Problem: Make a complex high-speed industrial process understandable and safely operable on a machine-mounted touchscreen.
Solution: Event-driven real-time UI, reusable design system, operator-focused workflows and visualizations for machine state, production batches, PCB flow, feeders, materials and alerts.
Result: Production-ready interface delivered for real hardware and demonstrated publicly on operating machines at Productronica.

Independent platform · 2025–present

NEXIS — Technical Workflow Automation

NEXIS is my platform for automating technical workflows: it ingests source material, extracts and organises information, flags missing context and prepares a verifiable output for the next decision. Under the hood it connects product applications, shared packages, CI/CD and AI-agent orchestration.

The project also required building a complete component design system, connecting multiple dependency layers and establishing component testing so the system could remain consistent and reliably extensible.

Role: Architect · Full-stack / Platform Engineer
Problem: Technical inputs arrive from multiple sources, and manually sorting them, checking completeness and moving context between steps is slow and error-prone.
Solution: I designed a controlled workflow from intake through extraction and context enrichment to output validation and explicit human decision points, backed by monorepo/package architecture, CI/CD, a data layer and reusable UI.
Result: The result is a reproducible system that reduces manual transcription, keeps sources and uncertainty traceable, and prepares material for downstream work without removing human control.

Conecterm — product data and catalogue automation

A production e-commerce platform connected to business data and a print workflow. Product data is transferred automatically from Money S3 through XML into the .NET CMS and then into the React frontend; sales staff can build print catalogues directly from current e-commerce data.

Role: Frontend Developer
Problem: Manually re-entering product data and assembling catalogues duplicated work, increased the risk of outdated information and made every catalogue dependent on technical or graphic-production work.
Solution: We connected an automated XML export from Money S3 to the CMS and product website. Sales staff can select the categories they need and generate a catalogue directly from current product data; my work also included layout and CSS styling for PDF and print output.
Result: A single product-data source now serves both the e-commerce site and printed catalogues. Sales staff can choose the required categories and create an up-to-date print output without manually assembling it.

Browser rendering experiment · 2023–2024

Color Player

A technical experiment focused on the limits of browser rendering, the event loop and performance when processing audio and graphics concurrently. It combines the Web Audio and Canvas APIs in an interactive application where smooth rendering, proper memory management and minimising main-thread blocking are essential.

Role: Frontend Engineer · Technical Experimenter
Problem: Explore browser rendering, graphics and audio interaction beyond conventional application and form-based UI.
Solution: Built an interactive browser experience with Canvas, WebAudio and performance-sensitive browser APIs.
Result: A live technical showcase demonstrating low-level rendering and media work in an interactive application.
