Fennis

Full-stack developer with a strong MERN foundation, able to build solid websites, automation tools, and advanced Telegram bots. I work on trading systems end-to-end — converting Pine Script to Python, implementing strategies, and building custom analytics. Comfortable with NumPy, pandas, Matplotlib, and more for data handling, visualization, and modelling. If you need trading tools, bots, or full web solutions delivered cleanly and fast, I can handle the entire workflow from idea to deployment.
