Fig 1.1 — During Maisie's tenure at Credit Suisse, her work was to diagnose issues with high-frequency trading systems to ensure accurate quotation of various equity and commodity positions. The window demonstrates a Bloomberg Terminal's DLIB<GO> function, displaying a local-volatility (LVLC) implied-vol surface for USD/SGD whose ATM term structure is bootstrapped from the annualized standard deviation of ECB daily log-return. The strike-axis smile, risk-reversal skews, and equities/commodity data are simulated ticks.

Fig 2.1 — During Maisie's tenure at Grab, vetting the third-party binaries that ship inside the company's mobile apps became an integral part of her job. The window demonstrates radare2 isolating parts of a notional anti-tamper solution, triggering the B.EQ at 0x3a2c to branch to the reject/log path at 0x3a44. Patching 0x540000c0 → 0x540000c1 flips the condition to B.NE, causing a failed verification (w0 == 0) to fall through to TRUST_OK and bypasses the anti-tamper check with a single-byte opcode mutation.

Fig 3.1 — During Maisie's tenure at Traveloka, responding to incidents such as the CrowdStrike outage in 2024 became an integral part of her job. The window shows a disassembly of CrowdStrike's kernel-mode driver (CSAgent.sys) using IDA Pro, where the graph view demonstrates an out-of-bounds array index (R8 = [RAX + R11*8], R11 = 0x14) that resolves to an unmapped kernel address and faults on dereference, the page-fault pattern behind a ring-0 bugcheck.

Fig 4.1 — Maisie's hobby with cameras, especially the Leica M8, led her to interesting places. Through reverse engineering the Fujitsu Softune REALOS-based firmware, she was able to uncover a secret 16-bit DNG mode that allowed for pictures with more dynamic range, colour accuracy, and low-light performance. The m8tool was never released publicly due to a significant risk of people permanently bricking their Leica M8 cameras.
