Systems & Embedded Cybersecurity Engineer · Fountain Pen Enthusiast


The Philosophy: Ink × Silicon

In an era saturated by disposable software, ephemeral notifications, and synthetic text, Pixelated Penmanship exists as an intentional counterbalance.

By day, I explore systems engineering, embedded cybersecurity, and resilient computing environments—working with low-level Linux primitives, hardware roots of trust (TPM 2.0, ARM TrustZone), and safety-critical standards.

Off-screen, I study mechanical writing instruments—fountain pens, capillary feed dynamics, filling architectures, and archival ink formulation. The common thread is craftsmanship: whether writing a bare-metal driver or tuning a gold nib on micro-mesh, true quality requires discipline, patience, and attention to tactile detail.


The Dual Arsenal

A side-by-side inventory of the digital toolchain and the analog desk setup:

Digital Toolchain & Systems

  • Core Languages: C, Python, Bash, Shell scripting
  • Systems & Security: Embedded Linux, Yocto, ARM TrustZone, TPM 2.0, AppArmor, cgroups, IEC-62443
  • Environment: Linux (Debian/Ubuntu, Arch), Git, Neovim, Tmux
  • Workstation: Custom mechanical keyboards, dual calibrated displays, Obsidian for knowledge management

Analog Rotation & Paper

  • Primary Workhorse: PenBBS 355 Bulkfiller (Tuned Fine-Medium)
  • Artisanal Ebonite: Mohi Moonrise & PLP Jumbo (Indian hand-turned ebonite)
  • Vintage Favorite: Sheaffer Imperial Touchdown Filler
  • Daily Inks: Pilot Iroshizuku (Tsukiyo / Kon-peki), Pelikan 4001 Brilliant Black
  • Paper Stock: Tomoe River 68gsm, Midori MD Cotton, Rhodia 80gsm

  • Embedded Security Study Roadmap
