Technical Projects

FBG Interrogator

C#/.NET + C/FreeRTOS — Proximion AB

Collaborated in a 6-person cross-functional team (EE/CE) as one of the primary developers for the PC-host layers and MCU firmware. Architected a preemptive multithreaded system (FreeRTOS/RISC-V) using binary semaphores to synchronize high-priority ISRs. Engineered a ~$500 4-channel 90Hz prototype matching performance of $10,000+ industrial systems. Developed a C#/.NET host with USB Bulk Transfer for sub-ms sensor readout.

Closed Source (Industry R&D)
.NET Sales Catalog Generator

C#/.NET — Sevan AB

Developed a cross-platform desktop application using Avalonia UI, enabling unified deployment across Windows, Linux, and macOS. Built an ETL pipeline to ingest CSV datasets and render print-ready PDFs programmatically. Replaced manual design workflows, reducing production time from hours to <3 minutes.

Open source release coming soon
B2B Scan-to-Order

Android / Kotlin — Sevan AB

Architected a fault-tolerant Android application using Kotlin Coroutines for asynchronous concurrency. Engineered a distributed data synchronization engine with automatic failover strategies (Firestore/REST). Integrated Google ML Kit for on-device barcode inference to enable scanning in low-connectivity environments.
