Hi, I'm Erfan 👋

17-year-old developer from Tabriz, Iran, focused on aerospace software, systems programming, and cybersecurity. I build simulations and learning projects around spacecraft software, guidance systems, and network security — most of these are ongoing, self-directed projects rather than production systems.

  • 🇮🇷 Based in Tabriz, Iran
  • 🚀 Interested in: flight software, GNC (guidance/navigation/control), embedded systems, and cybersecurity
  • 🌱 Currently learning: RTOS concepts, Ada, and satellite communication protocols (CCSDS)
  • 📫 Reach me on Telegram: @Kali_xu

🔧 Featured Projects

Project Language Description
Web Application Firewall Go A Layer 7 WAF with rate limiting, IP reputation, SQL injection/XSS filtering, and a custom rule engine.
Simorgh Flight Software C A bare-metal flight software stack for small satellites, inspired by NASA's F Prime and cFE frameworks — command handling, telemetry, and CCSDS-style messaging.
Lunar Ascent Python A 6-DOF launch vehicle guidance/navigation/control simulation, built to learn the fundamentals of ascent trajectory modeling.
StarConsensus Ada An experimental Byzantine fault-tolerant consensus protocol, exploring how satellite constellations could stay in sync despite node failures or GPS denial.
QuantumCommRelay Python An educational simulation of quantum key distribution (BB84 protocol) with entanglement swapping and decoherence effects.
SpaceGreenhouse Python A concept project for autonomous plant monitoring using computer vision — disease detection and health tracking, aimed at long-duration space missions.
Hermes Flight Comm C A prototype intercom system concept for EVA suits.
Wandering Being Python An experiment with spiking neural networks (~100K neurons, STDP) exploring predictive processing — a research toy, not a claim of consciousness.

Some of these are early-stage or exploratory — check individual repos for current status and README details.
