I am Melek Moalla, an AI engineering student at ESPRIT in Tunisia, building projects in machine learning, deep learning, computer vision, reinforcement learning, and software engineering.
I build intelligent software systems that connect machine learning, backend engineering, and product-facing interfaces into one coherent experience.
- 🧠 Applied ML & deep learning — plant genomics, disease detection, explainable surrogate models
- 👁️ Computer vision — real-time hand tracking, gesture recognition and AR interaction
- ⚡ Real-time systems — WebSocket streaming, Redis, observability dashboards
- 🧩 Full-stack AI products — FastAPI / Django backends with React and Flutter frontends
- 📚 RAG & NLP — knowledge-grounded assistants and workflow automation
- 🎮 Reinforcement learning — PPO agents, reward design and honest evaluation of what agents actually learn
- 🤖 Agent tooling — orchestrating Claude Code and Codex CLI agents side by side
I care about systems that are technically credible and actually usable: clean APIs, interpretable ML, and interfaces that make complex outputs feel actionable.

Activity, streaks, stats, languages, project cards and profile views refresh hourly and after profile updates. Contributions use UTC dates; today can still be completed without resetting the current streak. Live contribution calendar · Snapshot data. GitHub may take time to count new commits. Profile views retain the last good value if the counter is unavailable.
- Currently improving Reward Goblin, my reinforcement-learning playground for exploring reward hacking with real PPO agents and separate task-success evaluation
- Smarter RAG-driven experiences with strong retrieval quality and practical UX
- AI-first full-stack applications where backend intelligence directly shapes the interface
- Real-time computer vision and streaming systems that run reliably outside the notebook
- NLP and HR Tech workflows that automate real business decisions
- Evaluation tooling that checks what AI agents actually do, not just the score they report
