Project Concept

This project is an AI platform that lets teachers create their own “AI twin” using Amazon Bedrock models, n8n workflows, and a Spring Boot backend.
Teachers interact with specialized agents — Profile Configuration, Materials Configuration, Methodology Improvement, and FAQ — which update their profile, organize teaching materials, and build a reusable knowledge base. Uploaded PDFs/images are stored, OCR’d via Bedrock through n8n, chunked, embedded, and stored in PostgreSQL with pgvector for semantic search. Later, students will talk to a teacher-specific agent that answers using that teacher’s profile, materials, and FAQ.

Dan-Stefan MARTIN Team Lead RSVP Approved

Full-Stack Developer at CleanCode Solutions

Team Lead, Full-Stack Developer

I’m Martin, a full-stack developer with a strong front-end background and a Robotics student in Brașov. I work with Java, Spring Boot, React, TypeScript, Next.js and AI tooling to build modular, maintainable web apps. I’ve shipped production features used by thousands of users in healthcare and education and I like turning fuzzy requirements into clean, documented, testable systems. I’m especially drawn to e-learning, developer tooling and AI-driven products. I run on coffee, late-night refactors and long runs, and I’m currently in an arms race with AI agents that never have quite as much context length as I’d like.

I’m exploring robust prompt engineering and AI guardrails, especially ways to protect LLM agents from prompt injection and drift. I want to design patterns and evaluation loops that keep agents reliable, scoped, and auditable, and to connect with others tackling secure, deterministic AI systems.

I’m building a gamified e-learning platform for students—a multidisciplinary hub that turns skill development into an interactive, quest-driven experience. I’m experimenting with progression systems, soft-skill tracks, and light AI assistance to keep learners motivated and accountable.

Stefania Breazu RSVP Approved

UX/UI Designer at CleanCode Solutions

UI/UX Designer

I’m Stefania Breazu, a graphic designer and UX/UI designer passionate about creating visual identities and digital experiences that blend aesthetics, functionality, and the logic of thoughtful design. I work in branding, packaging, web design, and mobile interface design, and my approach always starts with a deep understanding of users and the real needs of the brands I collaborate with.

I love learning about marketing psychology, business models, and growth strategies. I’m interested in working with marketers, founders, or creative entrepreneurs who want to develop brands through strategic design and compelling storytelling. I’m passionate about understanding how design thinking can transform businesses and improve product-market fit. I enjoy collaborating with people who build innovative solutions and want to explore new problem-solving approaches.

I’m designing a full mobile experience focused on helping users eat healthier, save time, reduce food waste, and plan meals more efficiently. The project includes user research, UX flows, UI design (light & dark mode), and an upcoming prototype for a live demo. I’m continuing a personal series of custom car posters for automotive enthusiasts, exploring composition, depth, lighting, and texture to create visually striking artwork.
