GLOBE-CoP: Data Space Online Learning Platform
A cloud-native, Udemy-style learning marketplace (instructors publish HD courses and live webinars, learners get recommendations, forums and progress dashboards) deployed on Kubernetes (EKS/GKE) with full CI/CD and observability.
- Built the responsive frontend (ES6+, SASS, Flexbox/Grid) with search, enrolment, playlists and in-browser HLS video playback.
- Designed the backend: Node/Express REST APIs plus Flask micro-services for auth, Stripe/PayPal payments and recommendations, secured with JWT; RBAC for Admin/Instructor/Student.
- Dockerised every service and deployed with Helm to EKS/GKE; GitHub Actions and Jenkins pipelines build, scan and test (Jest, pytest, Selenium) and push signed images.
GREENUS: Ambassador learning & certification platform
A Udemy-style platform dedicated to training, evaluating and certifying Greenus ambassadors: on-demand courses, live webinars, structured certification paths, assessments, digital badges and a community layer.
- Architected and implemented the platform: on-demand video courses, live webinars, certification paths, assessments, digital badges and certificates.
- Built the responsive frontend (ES6+, HTML5, CSS3/SASS) and the backend: Node.js/Express REST APIs plus Flask micro-services for authentication, certification management, payments and recommendations, secured with JWT.
- Modelled data across PostgreSQL/MySQL and MongoDB for profiles, certification progress, content, community interactions and audit logs.
MoonBOT: energy-market signals and imbalance prediction
A trading-signal and monitoring platform for the Romanian intraday and imbalance energy markets. Live market data, generation-mix outage detection, automated client reports and an ML pipeline that predicts the system imbalance for the next intervals.
- Developed the Flask platform and its admin dashboard, including market-trend tables, live positions, client auto-reports and a notification centre.
- Built the generation-mix outage monitor on Transelectrica data and the ENTSO-E unit-unavailability feed, with alerts in the dashboard.
- Worked on the Imbalance Watch pipeline that trains and compares LightGBM, XGBoost, CatBoost, scikit-learn and neural-network models, plus a stacked ensemble.
ROSPIN-SAT-1: CubeSat on-board computer (ESA Fly Your Satellite!)
Software, infrastructure and quality strategy for a CubeSat OBC under ESA's Fly Your Satellite! Design Booster: layered RTOS firmware with CCSDS telemetry, an embedded CI/CD lattice, hardware-in-the-loop benches and telemetry anomaly detection.
- Designed the layered firmware architecture and tuned FreeRTOS/Zephyr scheduling, multi-bus I/O (I²C, SPI, UART, CAN) and packet-based CCSDS TM/TC with error detection, retries and configurable timeouts.
- Containerised ARM cross-compilation and built Jenkins + GitLab CI pipelines: static analysis (Cppcheck, Clang-Tidy), unit tests (Unity, Google Test), coverage (gcov/lcov), nightly builds, auto-deploy to remote benches via Ansible with rollback.
- Provisioned Debian/Fedora build farms, staging networks and VPN gateways with Terraform + Ansible; hardened with image scans (Trivy/Clair), key-only SSH, SELinux/AppArmor, nftables and VPN/VLAN segmentation.
