Work Experience

IoT Software Engineer – Python Developer at Pi
September 1, 2023 - September 1, 2025
Delivered and deployed a real-time data pipeline for acoustic parameter capture and audio recordings using Python asyncio and NSRT-mk4 via a serial interface. Architected a modular, event-driven data collection system with automatic logging and cloud-compatible formatting, and integrated continuous data flow into a central MongoDB Atlas instance for long-term storage, visualization, and reporting. Ensured 24/7 uptime with automated service recovery and health checks via Bash-based deployment scripts for unattended operation on Raspberry Pi. Reduced hardware costs from €20,000 to ~€500 per unit by designing a cost-effective NSRT-mk4 sensor pipeline.
IoT Software Engineer – Python Developer at Pi
January 1, 2023 - January 1, 2023
Developed a sensor-to-cloud data pipeline capturing continuous audio, spectral, and acoustic data from the BK2255 Class 1 SLM via Open Interface API. Logged high-resolution data locally to MariaDB with cloud data migration to MongoDB for remote access and long-term retention. Automated deployment using Bash scripts. Optimized queries for historical acoustic datasets, reducing retrieval time by ~40%.
Full-Stack Python Developer at Enviro Consult Bucharest
January 1, 2023 - January 1, 2023
Built a full-stack platform for real-time and historical acoustic data visualization. Implemented RESTful APIs using Quart, secured via JWT authentication with granular role-based access control. Rendered dynamic frontend views using vanilla JavaScript, Chart.js, and Leaflet.js for live map tracking and dashboards. Fully deployed on a private cloud server.
Software Development Intern at Enviro Consult Bucharest
March 1, 2022 - May 1, 2022
Contributed to a real-time data acquisition project involving audio and video capture triggered by environmental input. Gained experience with sensor-based automation, data stream control, and system integration, which later influenced Python-based data logging and monitoring projects.
