Field notes / 2026

Useful experiments, shipped with intent.

I’m Tasfiya Tabassum (@Quincunx33) — a security researcher and systems developer from Khulna, Bangladesh. I explore the seam between low-level systems, offensive security tooling, Linux virtualization, and experimental web interfaces.

About the Maker

Systems should feel useful before they feel impressive. Tasfiya’s work spans TypeScript, Python, real-time applications, browser APIs, userland x86 emulation, Linux kernel packaging, and responsible security research.
