🔬 About Me

I am an independent researcher and systems engineer working at the intersection of computational astrophysics, self-sovereign distributed infrastructure, reverse engineering, and applied AI orchestration.

  • 🔭 Solar Physics & Coronal Seismology: Developer of oscfit, an automated Bayesian framework and seismological inversion pipeline for decayless kink oscillations in solar coronal loops.
  • 🌐 Sovereign Infrastructure: Architect of the zero-cost-sovereign-computing cluster—an 11-node heterogeneous distributed topology operating across Cloud, Lab, Office, Home, and Nomadic segments on legacy and minimal-cost hardware with 20+ months of verified continuous uptime.
  • 📡 Biometrics & Protocol Reverse Engineering: Creator of pure-Python reference listeners, daemons, and command catalogs for biometric hardware terminals (ebkn-m61-protocol, zkteco-adms-server).
  • 🤖 Agentic Systems: Architect of openclaw, enabling WhatsApp-native multi-agent LLM orchestration for operational workflows.
  • 🎓 Academic Mastery: Completed 10 rigorous Computer Science tracks from Harvard University documented in the Harvard-CS50-Showcase.

🌟 Featured Open-Source Repositories

An Automated Bayesian Framework and Seismological Inversion Pipeline for Decayless Kink Oscillations in Solar Coronal Loops

  • Automated sub-pixel slit tracking, wavelet-based oscillation detection, and Bayesian MCMC fitting.
  • Direct seismological inversion of local plasma parameters and coronal magnetic field strength ($B$).
  • Submitted & in-review at the Journal of Open Source Software (JOSS) (Submission Status).

Reference Configuration for an 11-Node Heterogeneous Sovereign Compute Cluster

  • Version 2 release: 11 nodes spanning 5 segments (Cloud · Lab · Office · Home · Nomadic).
  • Invoice-verified marginal capital outlay of ₹51,525 (~USD 625) against historical acquisition cost ≥ USD 13,000.
  • Recurring cloud fees constrained to ≈ ₹300/month (~USD 3.60/month) across 20+ months continuous operation.
  • Multi-plane routing: mDNS local discovery → Headscale mesh VPN (100.64.0.0/10) → Cloudflare Tunnels → MCP federation.
  • Companion to publication: Zenodo 10.5281/zenodo.19654425.

Agentic LLM Orchestration Architecture for Operational Workflows

  • WhatsApp-native conversational dispatching for asynchronous tasks, inventory, and enterprise systems.
