DeCiTeL: Democratic Citizenship Teaching & Learning platform
The digital platform of the DeCiTeL Erasmus+ Teacher Academy for democratic citizenship education. A React and NestJS application with a resource repository, communities of practice and virtual exchanges, shipped through QA and production pipelines.
- Developed the web application (React 19, TypeScript, Vite, Tailwind CSS) on top of a NestJS, Prisma and PostgreSQL API with JWT authentication and Swagger documentation.
- Built the delivery pipeline in GitHub Actions; every push to main deploys to QA and every RELEASE commit promotes to production over Tailscale SSH.
- Wrote the Terraform for the Cloudflare Tunnel, DNS, Access and SSL settings that serve the production domain, and the Tailscale Funnel tunnels used for QA.

TerraformGLOBE-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.
HRS4R@UPB: Human Resources Strategy for Researchers
The website of POLITEHNICA Bucharest's Human Resources Strategy for Researchers (HRS4R), presenting how the university supports and develops its academic and administrative staff.
- Took over the existing PHP platform and updated it: code clean-up, dependency and security updates, and fixes across the site
- Redesigned the interface: a modern, responsive layout and clearer navigation, consistent on desktop and mobile
- Deployed and run it on the university's private cloud, with Docker and an Nginx reverse proxy on Linux

MySQLMoonBOT: 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.

PostgreSQLSIMPATIC: participant file and e-signature platform
A web platform where participants in the SIMPATIC training programmes check their data, sign their annexes electronically, upload an ID document and then download their continuing-education certificate, with an admin panel for the project team.
- Built the React and TypeScript frontend and the Express API with JWT authentication, SQLite storage and PDF generation.
- Implemented the signing flow (drawn signature applied to every annex, re-signing after changes, GDPR consent with its own PDF) and the final confirmation that unlocks the certificate.
- Built the admin panel with filters, editable participant files, issue tracking and streamed ZIP archives.
Performance Pay Platform for POLITEHNICA Bucharest
A web platform where POLITEHNICA Bucharest's teaching and research staff submit, and the university verifies and approves, applications for performance-based salary increases, fully online and with an audit trail.
- End-to-end delivery: React and Angular front ends in TypeScript and JavaScript, NestJS and Express APIs, cloud infrastructure on AWS and Azure with Kubernetes and Terraform, GitOps and GitHub Actions CI/CD, and the automations that run the process
- Electronic application flow: sign-in restricted to eligible staff, an application form built from the criteria each person selects, required-field checks and a unique registration number on submission
- Automatic verification: matching declared publications and patents against the university's reference lists and pre-filling their details, so applicants do not retype them
